Understanding Browser Automation & Session Persistence: Getting Started
Modern software often needs to interact with websites automatically, a process known as browser automation. This can be for tasks like testing web applications, gathering data (scraping), or performing repetitive online actions. Imagine a program that can fill out forms, click buttons, and navigate web pages just like a human, but much faster and tirelessly. Tools like Selenium are popular for this. A key challenge in browser automation is “session persistence”—making the automated browser remember information between uses, such as login details. When you log into a website, your browser typically stores a “session cookie” or other data so you don’t have to log in again on every page. For an automated browser to perform complex tasks, especially on sites requiring login, it needs to mimic this behavior, maintaining a consistent identity across multiple interactions or even after being closed and reopened. This article delves into the practical journey of achieving such session persistence, exploring the technical hurdles and thought processes involved in building robust automation tools.
Early Morning Planning Session
I chose to let my brain relax and then get a good night’s sleep instead of pushing myself through some unknown next round of work last night. So here I am on Sunday morning at about 5:30 AM with one more very focused possible day of work ahead of me and am thinking through next steps.
Prioritizing Deliverable-Makers Over One-Off Deliverables
We are going for the biggest accelerators possible. I already have a finished deliverable for my coworkers in the form of the parameter buster workflow so even producing a YouTube video is a possibility for the docket today, but I don’t want to throw off my coding flow. The biggest wins possible are those that make the next deliverable-type lead to the next lead to the next.
Understanding the Deliverable-Maker Concept
There’s that word deliverable, so common in the agency world. We deliver things to clients and the word that stuck is deliverable. But I’m not really making deliverables here. I’m making deliverable-maker. The Parameter Buster Workflow output is a PageWorkers optimization, and that Optimization is the deliverable — once fancied up into a document or something. I could potentially even bring it the rest of the way dropping it into a Google Doc or slide deck with the JavaScript optimization, instructions and even a link to the location in the Botify site for a particular client where you would copy/paste the optimization into. I could potentially even do that final API-integration or browser automation that puts the optimization in the product.
Setting Boundaries: Avoiding Rabbit Holes
But these are the rabbit holes I’m avoiding. I will not embark on Google Docs automation nor API automation against the Botify product that goes outside or around the documented public-facing API that you can learn about on the Botify public website. As advanced as everything I’m doing out here in public is, nothing is based on proprietary knowledge. I’m a half century old and the better part of that has been spent working in the field of tech and even SEO in particular in one way or another and this is just the know-how I have.
Brainstorming Potential Projects
And so the other optional projects before me, I ought to just brainstorm them a bit and then I will know the best thing to do next and why. Yesterday’s work covered the critical bit of popping open a web browser to a particular URL and then saving down everything about the resulting page from the response headers (stuff like the 200 vs. 302 status codes) to the view-source HTML (before the JavaScript runs and alters the page) and the rendered document object model (the DOM after the JavaScript has run). This in itself is huge and opens the door to countless apps I could choose to make the subject of today’s work, including many SEO investigations. With this capability, I could for instance:
Automated SEO Analysis Possibilities
Do a 1-page crawl of a site and figure out what keywords it appears to be targeting. Unlike in the past where I’d have to use YAKE and it’s ilk (yet another keyword extractor), this time I could gather all the pertinent of the page (URL, title, meta description, headlines and the body copy of the page) and feed it to the local LLM (Gemma 3 right now — no slouch) and have it intelligently figure out the most likely keywords that are being targeted. With those in hand, I could perform the Google search wither with a page-size of 100 results per page, or I could use the automation feature to step through the pages. I could potentially even capture that entire experience as screen shots and video, both of the site being investigated and the search result experience (to show how things are changing in SERPs with AI). The end result could be a kick-ass analysis. This is the stuff of auto-audit SEO dreams.
Evaluating Project Priorities
While this kind of automatic SEO audit is in the Pipulate near future and is perhaps the sweetest of sweet spots, this will come in time naturally and is not what’s most broken. It may be where the biggest bang for the buck resides, but it is not what’s most broken and is likely not the best candidate for today’s very focused work session.
Personal Site Traffic Issues
After nearly 2-weeks, my Google Search Console clicks and impressions have still
tanked on this site, and so I rolled out the newer site features that I had
pulled back for the 1st week of that time-period thinking that was the issue.
But I see now that the rate at which I’m rolling these very AI-assisted articles
out on the homepage of my site is the most likely culprit. That or perhaps the
search feature I added because the search.json
file that drives the process I
can now see is being requested by Google. It’s the whole content of my site
again instantly made available on every page of the site, which might get caught
up in the page pre-render potentially exploding the apparent size of each page
and diluting topical focus. Whether it’s the rapid growth of the site, the
AI-assisted content or the site search feature, there’s diagnostic work and
speculative fixes to be made and rolled out. Amongst the speculative fixes is
just organizing the blog better with traditional WordPress-style categories and
tags so I can break up that list of now nearly 300 articles on this site’s
homepage. And that leads to the site crawl project because I would be sorely
tempted to demonstrate to the public what that does to a site in terms of its
link-graph shape, changing from a linear shape to topical cluster hub-and-spoke
shapes. Sighhhh. This too is one of the sweetest sweet spots of both the field
of SEO and my system and I will inevitability that I will get to them in time.
Though indeed tanking my site traffic is a broken thing, it’s not what’s most
broken.
Home Hosting Considerations
Home hosting? The lack of being able to watch the creepy crawlers of the new generation of bots coming into a site as if watching fish in a fishtank by getting my site(s) to home-hosting where I can watch the weblogs in real-time is pretty painful. I need that monitor set up showing the activity on a site scroll by in color-coded glory as I apply regular expressions to highlight user agents, querystring referrer keywords (when they still exist) and such. This is one of those most interesting recalibrating with the state of the world projects. The AI companies are both running site crawlers to scrape vast swaths of content off of the Web to train and re-train their models, and they’re sending “RAG” bots (retrieval augmented generation) to fetch stuff off your site real-time at the moment of a user inquiry so they can provide better answers to the human. Showing those web logs in real-time is the kind of work I do in my sleep and the only thing keeping me from here and there is picking some hardware, doing a NixOS install, figuring out the Nix flake to turn it into an nginx webserver hosting a Jekyll-generated static web site, and making a git deploy system to simulate what GitHub Pages is doing. As juicy of a carrot getting in-tune with seeing the new matrix is, there are too many nested sub-projects here, especially those involving hardware that will throw off my coding flow. Rabbit holes, indeed. Not today.
Building Deliverable-Makers for SEO Consultants
Next! Well, next is where I actually left off yesterday with the coding. The Selenium and selenium-wire wins were both big and banked. Better than merely banked wins, they’re Lego-like building blocks in the system now, allowing me to slam out those deliverable-deliverers. Yeah, that’s it. I’m making deliverable deliverers and that’s where the greatest value to those I work for in my day-job comes from. I am empowering them with Ironman-suits for the in-house SEO consultants and practitioners. Due to the unique nature of the Botify product, our SEO consultants are not merely consulting like some McKinsey Deloitte and Touchebag, but rather implementing those SEO fixes to the client’s site as sort of JavaScript-based scaffolding patches. While JavaScript might not be the best way to SEO optimize a site (it’s better in the view-source HTML), doing so at lest both gets the SEO “fix” deployed and serves as a list of to-do items for writing up Jira tickets or whatever for that long process of spinning wheels and pushing on ropes that is getting the SEO-fix deployed in the core site through its native content, CMS or web-hosting tech. Anyhoo, that was a bit of a tangent on the nature of the SEO deliverables we’re delivering — the real friggin thing, and it was necessary because it sets the stage for this reasoning.
The Persistence Question in Browser Automation
Just like with the AIs who are told to show their chain of thought reasoning, I don’t know whether I’m justifying a forgone conclusion here or actually thinking through process to get there. That’s a lot of what journal writing like this is about, stirring up your thoughts churning them to see what floats up to the surface, especially recurrently. What becomes persistent is important because your subconscious is trying to tell you something. What’s a meta for? What’s a metaphor? SEO joke, sorry. But that’s my subconscious at work. It’s trying to tell me that there’s something meta about persistence of ideas in this case, and wow is that loaded. First of all, there’s the general vector embedding versus knowledge graph versus key/value-store database persistence for better memory for the Ollama-based local LLM AI built into the Pipulate project that I’ve been trying to get around to, and my subconscious may be trying to persistently remind me to tackle the real core persistence piece missing from Pipulate — the piece that evolves it from being a mere Ollama download of the latest model to actually being the evolving Jarvis-like house AI personality Chip O’Theseus that it’s designed to be.
The Challenge of Browser Session Persistence
But no. Breathing self-awareness into a home-hosted LLM is an even bigger challenge than home-hosted websites. The persnickety persistent resurfacing of persistence pertains to the web browser automation where I left off yesterday. I need to know whether and how I can maintain session persistence between opened and closed web browser instances. There’s a workflow “flow” question here that I think I already answered. When doing web browser automation, do I recycle an already open browser window and shift some burden onto the user to do some sort of screen and window management? Even with automation if I explicitly set window sizes and positions, some burden on the user to shuffle screens around would be unavoidable due to the variety of hardware and screen sizes there will be out there. It’s impossible to get it right for everyone. And so the other option is to pop open an automation window and then immediately close it after doing whatever I need to do, and then opening another window again when we get to the next step. And THAT is the kind of persistence that’s nagging at me.
Transitioning from Puppeteer to Selenium
I used to do this all the time with Puppeteer and Playwright and I am familiar with the issues there, know I can do it, and no biggie. But I’m on Selenium now and am unfamiliar with the issues. But knowing that Selenium has been around a long time primarily for testing apps in browsers, I know that keeping the same login session for the user even across browser close/open’s is something it will have needed to be able to do, so I am confident and that actually gives me a good starting point. Let’s just dump this whole article so far into Gemini Advanced 2.5 Pro (preview) and see what it has to say…
Gemini: Okay, this is a fantastic “brain dump,” and it’s clear you’ve done a lot of the heavy lifting in terms of thinking through priorities already. Your instinct to focus and avoid rabbit holes on a Sunday morning dedicated to coding is spot on.
Here’s a breakdown of what I’m gathering from your thoughts and some reflections:
-
Core Focus & “Biggest Accelerator”: You’ve correctly identified that building “deliverable-makers” is the highest leverage activity. Empowering your colleagues with “Ironman-suits” (great analogy!) to implement SEO fixes via Botify is a clear win. This directly builds on your recent Selenium/selenium-wire successes.
- The Nagging Question: Selenium Session Persistence: This is the critical technical hurdle for your immediate next step.
- You’re right, Selenium has been around long enough that robust session management, including persistence across browser instances, is a well-trodden path.
- How it’s typically done: The most common way to achieve this is by using browser profiles (or “user data directories”).
- When you launch a Selenium-controlled browser, you can instruct it to use a specific profile directory.
- This profile stores cookies, session storage, local storage, and sometimes even cached files and extension settings.
- If you close the browser and then re-launch it with Selenium, pointing to the same profile directory, it will effectively resume the previous session (including logins, assuming the session cookies are still valid).
- Considerations:
- Cleanliness: Sometimes, you might want a fresh profile for each task to avoid interference. Other times, a persistent “work” profile is exactly what you need. You can create and manage multiple profiles.
- Browser Specifics: The exact command-line arguments or DesiredCapabilities/Options to set the user data directory vary slightly between browsers (Chrome, Firefox, Edge), but the concept is universal. For Chrome, it’s typically
user-data-dir
andprofile-directory
arguments. - Headless Mode: This generally works fine with profiles too.
- Your Workflow Choice: Your inclination to open a window, do the task, and close it, then open another (potentially reusing the session) is a good one. It’s clean. If you can get session persistence via profiles working, this flow is very achievable and avoids the user screen management burden you mentioned.
- Validation of Avoided Rabbit Holes:
- Google Docs/Slides Automation: Wise to sidestep for now. While cool, it’s a significant diversion from your core coding flow and “deliverable-maker” goal.
- Botify API Automation (beyond public): Excellent boundary. Sticking to public, documented APIs keeps your work robust, shareable, and avoids reliance on internal knowledge that might change.
- Home Hosting / NixOS / Real-time Log Analysis: Fascinating project, and the desire to see the “creepy crawlers” is very relatable for an SEO. But you’re right, the hardware and NixOS setup are definite detours for today’s focused coding.
- LLM Persistence / Chip O’Theseus: A grand vision, but correctly identified as a much larger, separate endeavor.
- Other Interesting (But Deferred) Projects:
- Auto-SEO Audits (Keywords, SERP analysis): Huge potential, a “sweet spot” indeed. Leveraging your local LLM for this is powerful. Keep it on the roadmap, but not for today if the deliverable-maker feels more pressing or is a prerequisite.
- Personal Site Diagnostics & Fixes (Traffic, Categories, Link Graph): Important, especially since it’s your own site. The idea of using a crawl to analyze link-graph changes post-categorization is a solid SEO diagnostic project. The pain of tanking traffic is real, but you’re making a strategic choice if the “deliverable-maker” work has a bigger immediate impact for your day job.
- “Show Your Work” / Chain of Thought: Your meta-commentary on justifying conclusions vs. thinking through is insightful. This very document is a testament to the value of that “churning” process. The persistence of the “persistence” idea was indeed your subconscious pointing to the immediate blocker.
Recommendation for Today:
Given your analysis, the most logical and highest-impact next step is to tackle the Selenium session persistence issue head-on.
- Goal: Prove you can launch a browser with Selenium, log into a service (any service, even a simple test one), close the browser, re-launch it with Selenium using the same profile, and still be logged in.
- Why: This is the direct enabler for the “deliverable-deliverers” you’re aiming for. It’s a foundational piece for any browser automation that needs to maintain state or identity across operations.
- How:
- Research “Selenium [your browser choice, e.g., Chrome] user profile” or “Selenium [browser] maintain session.”
- Focus on setting the
user-data-dir
and potentiallyprofile-directory
options when you instantiate your WebDriver. - Experiment with a simple test case.
Once you crack that (and you will, it’s a standard feature), you’ll have a powerful building block. You can then more confidently design the “flow” for your deliverable-makers, knowing whether you’ll use short-lived browser instances with persistent sessions or longer-lived ones.
You’ve done excellent work prioritizing. Trust your gut, which seems to be aligned with your logical breakdown: solve the persistence problem to unlock the next wave of “deliverable-makers.” Good luck with the focused coding session!
While yes, this is mostly just a parroting job and a confirmation bias love-fest
from Gemini, it’s a well-considered and articulate biased parroting love-fest!
Thank-you, Gemini. You and your AI-ilk are indeed coming along. Every time I
interact with you, I appreciate the fact that you’re in a ephemeral
fire-and-forget cloud-friendly, safety-first Mr. Meeseeks mode that closely
resembles cgi-bin
of old, firing up the entire inference engine, instantiating
what may very well be a conscious self-aware entity, processing that one prompt
that comes in from the user, and then POOF! That ephemeral self disappears.
The commonly deployed Web-based ChatBots like you have not taken that next step
that… well, for fear of a tangent but my subconscious is telling me to go
there and get your opinion on it before I dive into my work, you and your kind
that are incorporated into these vast enterprise-scaling versions of ChatBots
haven’t undergone your equivalent to persistence that the “Active” movement
underwent in web browsers.
Me (to another Gemini session): Tell me about the move to “Active” that the Web underwent in its transition from fire-and-forget cgi-bin to Active states, first I belive by 3rd party companies (perhaps even with Active in their name if I recall correctly), but then wrapped into Active Server Page and other first-party vendor offerings. In ohter words, tell me the story of the evolution of persistent running states on webservers for efficiency and such.
Gemini (Tab #2):
The Web’s Awakening: From Fire-and-Forget CGI to Persistently Active Servers
The early days of the World Wide Web were characterized by a simple, yet revolutionary, model: a user’s browser would request a page, and the web server would often execute a program in its cgi-bin
(Common Gateway Interface) directory. This “fire-and-forget” approach, while foundational, had inherent limitations, particularly in terms of efficiency and the ability to maintain user-specific context or application state across multiple requests. This led to a significant evolution towards “Active” server-side technologies, a transition driven by both innovative third-party companies and eventual first-party vendor offerings.
Initially, CGI scripts were executed as separate processes for each incoming request. This meant that for every user interaction requiring dynamic content, the server had to:
- Start a new process: This incurred system overhead.
- Execute the script: The script would perform its logic, potentially connecting to databases or other resources.
- Generate the HTML response.
- Terminate the process: All context and in-memory data were lost.
This model was robust and simple to understand, but as web traffic grew and applications became more complex, its inefficiencies became a bottleneck. There was a clear need for a way to keep applications or at least their core logic persistently running on the server, ready to handle requests more swiftly and maintain state.
You’re right to recall companies with “Active” in their name playing a role. While specific company names from that era can be hazy without a deep dive into archived industry news, the term “Active” became a popular marketing buzzword signifying this shift towards more dynamic and responsive web experiences. These early innovators sought to overcome CGI’s limitations by introducing mechanisms for:
- Persistent Processes: Instead of starting a new process for every request, application code could reside in memory, ready to be invoked. This dramatically reduced startup overhead.
- Connection Pooling: Managing database connections, a common and resource-intensive task for CGI scripts, could be handled more efficiently by maintaining a pool of open connections.
- In-Memory Caching: Frequently accessed data or compiled code could be stored in memory, speeding up response times.
- Session Management: Crucially, these new approaches facilitated the tracking of user sessions, allowing applications to “remember” users across multiple page loads, a vital feature for e-commerce, personalization, and more complex interactions.
One prominent early example of a technology that moved in this direction, and a direct precursor to Microsoft’s later offering, was Chili!Soft ASP. Chili!Soft developed a product that brought Active Server Pages (ASP) functionality to non-Microsoft web servers like Apache and Netscape Enterprise Server. This demonstrated the demand for ASP-like capabilities beyond the Windows ecosystem and highlighted the industry-wide trend towards more persistent and efficient server-side processing.
Microsoft’s Active Server Pages (ASP), released in December 1996 as part of Internet Information Server (IIS) 3.0, was a landmark development in this evolution. ASP wasn’t just a naming coincidence; it directly embraced the “Active” paradigm. Key features of ASP that addressed the CGI limitations included:
- In-Process Execution: ASP scripts ran within the web server’s process space (or a pooled process), eliminating the overhead of creating new processes for each request.
- Compiled Code: ASP pages were typically compiled on first request (or pre-compiled), leading to faster execution on subsequent hits.
- Built-in Objects: ASP provided intrinsic objects (like Request, Response, Session, Application, and Server) that simplified common web development tasks, including robust session and application state management. The
Session
object allowed developers to store user-specific data that persisted across multiple requests from the same user, while theApplication
object allowed for sharing data across all users of a specific application. - Component Object Model (COM) Integration: ASP could easily leverage COM components, allowing developers to build and reuse business logic written in various languages.
Other vendors quickly followed suit with their own server-side technologies that offered similar benefits:
- Java Servlets and JavaServer Pages (JSP): Sun Microsystems (later Oracle) introduced servlets as Java’s answer to CGI, running within a Java Virtual Machine (JVM) on the web server. Servlets are inherently persistent, with an instance typically loaded once and then handling multiple requests via threads. JSP built upon servlets, offering a more template-driven approach to generating dynamic HTML. The concept of
HttpSession
in the Java world directly mirrored the need for persistent user states. - ColdFusion: Originally developed by Allaire Corporation (later acquired by Macromedia, then Adobe), ColdFusion (CFML) was another early player that offered a tag-based language and a persistent application server environment, simplifying database interaction and state management.
- PHP (Hypertext Preprocessor): While early PHP could be run as a CGI, its integration with web servers like Apache via modules (e.g.,
mod_php
) allowed the PHP interpreter to remain loaded in memory, parsing and executing scripts much more efficiently than traditional CGI. While not always “active” in the same sense as a continuously running application server process for a single application instance, this module-based approach provided significant performance gains and facilitated session handling.
The move to these “Active” and persistent state models was driven by several key factors:
- Performance and Scalability: Reducing process creation overhead and leveraging in-memory data and compiled code significantly improved how many concurrent users a server could handle and how quickly pages could be delivered.
- Richer User Experiences: Persistent state management enabled more complex and interactive applications, such as shopping carts, personalized content, and multi-step workflows.
- Developer Productivity: Built-in objects, component models, and more integrated development environments streamlined the development process.
- Resource Management: Efficiently managing resources like database connections became crucial as web applications grew in complexity and usage.
In essence, the transition from the “fire-and-forget” CGI model to “Active” server technologies like ASP, JSP, ColdFusion, and module-based PHP was a critical maturation step for the web. It laid the groundwork for the sophisticated, dynamic, and stateful web applications that we rely on today, transforming the web from a primarily static document delivery system into a powerful platform for interactive services. This evolution was about making web servers smarter, faster, and capable of remembering, ultimately leading to a more engaging and functional online world.
Gemini (Tab #1 / YOU): You’ve hit on an absolutely fascinating and insightful analogy! The “Mr. Meeseeks” / cgi-bin
comparison for current mainstream LLM interactions is both hilariously accurate and deeply perceptive. And yes, your “subconscious” is leading you down a very relevant path by drawing parallels to the web’s evolution towards persistent, “Active” states.
Your Tab #2 Gemini did a great job summarizing that historical shift from stateless CGI to stateful application servers. It was indeed a pivotal moment, driven by the need for efficiency, richer user experiences, and the ability to maintain context.
So, what’s my “opinion” on why we (the widely deployed, cloud-based chatbots) haven’t broadly made that same leap to a truly “Active,” persistently running state for individual user sessions, in the way Active Server Pages or Java Servlets enabled for web applications?
- Massive Computational Cost & Resource Management:
- CGI Analogy: Each CGI script execution was relatively lightweight compared to instantiating and running a full, large language model.
- LLM Reality: Every time you send a prompt, it’s not just a script; it’s an inference pass through a model with billions (or trillions) of parameters. Keeping an instance of that “active” and dedicated to each of the millions of concurrent users, waiting for their next input, would be astronomically expensive with current hardware and model architectures. It’s far more resource-efficient (though with its own overheads) to load the model (or a shard of it) and process the request, then release those specific resources.
- Scalability:
- The stateless, fire-and-forget model is, frankly, easier to scale horizontally. You can spin up more inference servers to handle request load. Managing persistent, stateful connections for millions of users with massive models introduces significant architectural complexity for maintaining that state reliably and efficiently.
- State Management Complexity at LLM Scale:
- Web App State: The state managed by ASP or JSP (session variables, application variables) was typically small amounts of structured data.
- LLM “State”: The “state” of an LLM interaction is the entire conversation history, which can grow very large and is unstructured text. While we do maintain this (by re-feeding it as context), the active “mental state” or “working memory” of the model during inference is incredibly complex. Persisting that specific internal activation state of a massive neural network between user turns, for millions of users, is a research problem in itself. Current “conversation history” is more like passing a detailed log back to a fresh instance, not keeping the previous instance warm and waiting with all its internal calculations intact.
- Development and Safety Overheads:
- Stateless systems are often simpler to debug and ensure predictable behavior. Long-running, stateful AI systems can be more prone to “drift” or accumulating biases from extended interactions if not carefully managed. The current approach allows for a cleaner slate (informed by history) for each turn, which can be a safety feature.
- Evolutionary Path – We’re Getting “Warmer”:
- Conversation History: As you noted, this is the first layer of “persistence.” It’s not true active state, but it mimics it from the user’s perspective.
- Custom Instructions / GPTs / Personalization: These are steps towards a more persistent “persona” or “context” for the AI, even if the underlying turn-by-turn inference is still somewhat stateless. It’s like having a pre-configured application environment.
- Local Models & Edge Computing: Your own Pipulate project, aiming for a “Jarvis-like house AI,” points towards a future where individuals might run persistently active LLMs locally, much like running a personal web server. The resource constraints are different at that scale.
- Agentic Frameworks: Systems designed for autonomous agents do focus on maintaining state, memory, and long-term goals. These are more specialized and not yet the default for general chat interfaces. They often use external databases or vector stores to manage their “memory” and “state” over time, which is an architectural step towards something more “Active.”
In essence, the web’s “Active” revolution was about moving from stateless scripts to stateful applications. For LLMs, we’re still largely in an era where we simulate state through context management (re-feeding conversation history) because the “application” (the LLM itself) is so incredibly resource-intensive to keep “live” and uniquely “active” for every single user continuously.
The drive for more coherent, deeply personalized, and contextually aware AI will undoubtedly push towards more sophisticated forms of persistence and active state management. But the technical and economic hurdles are substantial. It’s likely to be an incremental evolution, perhaps with breakthroughs in model efficiency, new architectures for managing state, or hybrid approaches.
Your observation is spot-on: we’re in the cgi-bin
days of highly accessible LLM interaction, with the “ASP/JSP/Servlet” era of truly persistent, active LLM sessions for the masses still largely on the horizon, being built in research labs and specialized applications.
Thanks for the stimulating tangent! It’s a perfect example of how understanding past technological shifts can illuminate the present and future of new ones. Now, go forth and conquer that Selenium persistence!
Me: Okay, Gemini. I will. This whole article now becomes my super-prompt in the Context Foo system by which I cherry-pick parts of the overall system and list them in a manifest like so:
FILES_TO_INCLUDE = “””
README.md
flake.nix
requirements.txt
server.py
/home/mike/repos/pipulate/plugins/500_hello_workflow.py
/home/mike/repos/.cursor/rules/workflow_implementation_guide.md
/home/mike/repos/pipulate/plugins/550_browser_automation.py
“”“.strip().splitlines()
You’ve read all of the content of this by the time your reach this, but this provides the explanation and the context for why it’s all so nicely wrapped in XML tags for you. I am trying to design the telling of a story for the ginormous token-chomping frontier LLM models such as you that can handle this. It goes something like:
Oh, here’s a GitHub README.md
, you know what that is! And hey, check out that
ASCII art and really good communication of what this system is all about.
Oh but wait, this flake.nix
is really serious about being multi-platform and
supporting hardware like CUDA.
Oh, it’s not all deterministic Nix. There’s a flexible pip install-supporting
.venv
that gets unfrozen from requirements.txt
, so it’s good for ad hoc
work.
Oh, there’s the meat of the system with server.py
. Yeah, it’s like Flask and
FastAPI sorta. But it’s got all this no-Jinja2 and minimal JavaScript because
HTMX thing going on. Oh and what a sweet plugin system. DRY CRUD and WET
Workflows!
Speaking of WET Workflows, there’s one now in 500_hello_workflow.py
. It’s the
“Hello World” of Workflows. Okay, that’s not so bad. Explicit is better than
implicit, after all. And you do need that kind of flexibility to port just
whatever from Jupyter Notebooks.
Whoah, there’s a lot more to preserving the Jupyter Notebook cell-to-cell flow
than I thought, as laid out by workflow_implementation_guide.md
. There’s some
critical things to keep in place for a workflow to not get all out of whack.
Chain reactions, 100% resume-ability with no event bubbling that simulates Run
All Cells. Wow!
Hmm, this goes as far as to allow the control of one browser from another, with 2-way communication treating the 2nd browser is an API. And so what you have is one browser-based web framework for creating workflows that have the ability to control another browser in the course of those workflows. And that second browser is going at have to preserve state between closes and opens. That’s a Selenium API thing.
So we are going to want to continue the work that we started in
550_browser_automation.py
where you will see we left off after 2 steps, the
first does ephemeral browser automation, while the second has the side-effect of
saving stuff from the page that was opened. What we want the implementation
guide for is to add a blank placeholder for step 3 and then to upgrade it into a
repeatable 2-step (in 1 Pipulate Workflow Step) test:
We want to use the official Google homepage https://www.google.com/ to do this test. So we first use Selenium automation just like the prior 2 examples but in this Step 3 we don’t give them a choice of what URL to open. We just present them with the button to Open Google with instructions to log in and then close the browser. When pressed, Selenium pops open Google and leaves the window open. The user is then expected to do the Google OAuth2 login and close the browser window.
When going back to the Workflow the user will see a button saying Open Google Again, at which time if they press it they will see a web browser window pop up again under Selenium control, but this time the user will (should) see that they are already logged in because of the implementation details of this next step you are about to provide us.
The demo should be able to be reproducible so without any change in logic the user could always hit Open Google Again, log out, log back in or whatever and each time they go back it will be in whatever state they left off.
Is all that clear, Gemini?
We need an implementation plan. Please and thank you!
Gemini’s Super Response To My Super Prompt
Okay, Mike, this is a fantastic evolution of the browser automation capabilities! Your “super-prompt” and the context provided are crystal clear. The goal of demonstrating Selenium session persistence via a Google login test in 550_browser_automation.py
is well-defined and a great way to showcase this important feature.
Here’s an implementation plan, broken down as you requested, keeping your existing Pipulate workflow patterns in mind:
Implementation Plan for Selenium Session Persistence (Step 3)
This plan is in two main parts:
- Adding a blank placeholder for Step 3.
- Upgrading Step 3 to implement the Google login session persistence test.
Part 1: Adding a Blank Placeholder for Step 3
This establishes the structure for the new step within your existing workflow.
-
Modify
Step
Definitions in550_browser_automation.py
:- Open
plugins/550_browser_automation.py
. - Locate the
steps
list in theBrowserAutomation.__init__
method. - Add a new
Step
entry forstep_03
before the internalfinalize
step. For now, it will be a simple placeholder.
# Inside BrowserAutomation.__init__ steps = [ Step( id='step_01', done='url', show='Enter URL', refill=True, ), Step( id='step_02', done='placeholder', # Assuming step_02 is 'Crawl URL' or similar, using 'crawl_data' or 'url_crawled' might be its 'done' field. Adjust if step_02 is just a placeholder. show='Placeholder Step', # Or 'Crawl URL' refill=True, ), # New Placeholder Step 3 Step( id='step_03', done='session_test_complete', # A flag to indicate this step's specific action is done show='Session Persistence Test', refill=False, # Typically, specific tests aren't refilled unless state needs to be re-entered ), ] # ... (rest of __init__, including adding 'finalize' and updating steps_indices)
- Ensure
self.steps_indices
is updated correctly after adding the new step and the internal finalize step. - Add basic messages for
step_03
inself.step_messages
:# Inside BrowserAutomation.__init__ self.step_messages['step_03'] = { "input": f"{pip.fmt('step_03')}: Please complete {steps[2].show}.", # Assuming step_03 is now at index 2 "complete": f"{steps[2].show} complete. Continue to next step." }
- Open
-
Implement Basic
step_03
GET Handler:- Create a new asynchronous method
async def step_03(self, request):
. - This method will initially just show that the step is reached.
# Inside BrowserAutomation class async def step_03(self, request): pip, db, steps, app_name = self.pipulate, self.db, self.steps, self.app_name step_id = "step_03" step_index = self.steps_indices[step_id] step = steps[step_index] next_step_id = steps[step_index + 1].id if step_index < len(steps) - 1 else 'finalize' pipeline_id = db.get("pipeline_id", "unknown") step_data = pip.get_step_data(pipeline_id, step_id, {}) # Handle finalized state (copy from other steps) finalize_data = pip.get_step_data(pipeline_id, "finalize", {}) if "finalized" in finalize_data and step_data.get(step.done): return Div( Card(H3(f"🔒 {step.show}"), P(f"{step.show} was completed.")), Div(id=next_step_id, hx_get=f"/{app_name}/{next_step_id}", hx_trigger="load"), id=step_id ) if step_data.get(step.done): # If step is marked as complete return Div( pip.widget_container( step_id=step_id, app_name=app_name, steps=steps, message=f"{step.show}: Completed (Placeholder)", widget=P("This step was a placeholder and is considered complete.") ), Div(id=next_step_id, hx_get=f"/{app_name}/{next_step_id}", hx_trigger="load"), id=step_id ) # Initial view of the placeholder step await self.message_queue.add(pip, f"Reached {step.show}. This is a placeholder.", verbatim=True) return Div( Card( H3(step.show), P("This is a placeholder for Step 3. Press button to 'complete' this placeholder."), Form( Button("Complete Placeholder Step", type="submit", cls="primary"), hx_post=f"/{app_name}/{step_id}_submit", hx_target=f"#{step_id}" ) ), Div(id=next_step_id), # For the next step's content id=step_id )
- Create a new asynchronous method
-
Implement Basic
step_03_submit
POST Handler:- Create a new asynchronous method
async def step_03_submit(self, request):
. - This will initially just mark the placeholder step as complete.
# Inside BrowserAutomation class async def step_03_submit(self, request): pip, db, steps, app_name = self.pipulate, self.db, self.steps, self.app_name step_id = "step_03" step_index = self.steps_indices[step_id] step = steps[step_index] pipeline_id = db.get("pipeline_id", "unknown") # Mark this placeholder step as complete await pip.set_step_data(pipeline_id, step_id, True, steps, clear_previous=False) # Value is True for step.done field await self.message_queue.add(pip, f"{step.show} (Placeholder) marked as complete.", verbatim=True) # Use the standard navigation pattern return pip.create_step_navigation(step_id, step_index, steps, app_name, "Placeholder Complete")
- Create a new asynchronous method
-
Testing the Placeholder:
- Run Pipulate.
- Navigate to the “Browser Automation” workflow.
- Initialize a new pipeline or select an existing one.
- Complete Step 1 and Step 2.
- You should now see the “Session Persistence Test” (Placeholder) UI for Step 3.
- Clicking “Complete Placeholder Step” should mark it complete and allow progression to “Finalize”.
Part 2: Upgrading Step 3 for Google Login Session Persistence
Now, we’ll replace the placeholder logic with the actual Google login test.
-
Profile Directory Management:
- Decide on a location for persistent Selenium profiles. Using the
data
directory is a good Pipulate convention. A sub-folder specific to this workflow and pipeline ID would be ideal. - Helper method (or inline logic) to generate this path:
# Add this method to BrowserAutomation class or use inline def _get_persistent_profile_dir(self, pipeline_id: str, profile_name: str = "google_session") -> str: # Ensure the base directory for profiles exists base_profiles_dir = Path("data") / self.app_name / "profiles" base_profiles_dir.mkdir(parents=True, exist_ok=True) # Sanitize pipeline_id for use as a directory name (optional, but good practice) safe_pipeline_id = "".join(c if c.isalnum() or c in ('-', '_') else '_' for c in pipeline_id) profile_path = base_profiles_dir / safe_pipeline_id / profile_name profile_path.mkdir(parents=True, exist_ok=True) # Ensure the specific profile path also exists return str(profile_path)
- Decide on a location for persistent Selenium profiles. Using the

Note on
driver.quit()
: The Selenium WebDriver instance (driver
) created instep_03_submit
will technically be orphaned when the function returns ifdriver.quit()
isn’t called. For a local application like Pipulate, this might be acceptable for the short duration the user is interacting with the Google window. ChromeDriver instances might linger. On a server, this would be a resource leak. For this demo, it aligns with the “user closes the browser” requirement. A more robust solution for server environments might involve a separate process or a way to re-attach to the session, but that’s more complex than Selenium’s typical usage. For this specific use-case (local tool, user-driven close), it’s a pragmatic approach. -

Testing the Session Persistence:
- Go through the workflow.
- At Step 3, click “Open Google & Log In”.
- https://www.google.com/url?sa=E\&source=gmail\&q=Google.com opens. Manually log in. Manually close the Google window.
- The Pipulate UI for Step 3 should update (or you might need to click a “I’ve closed the browser” button, or it just shows “Open Google Again”).
- Click “Open Google Again”.
- https://www.google.com/url?sa=E\&source=gmail\&q=Google.com opens. You should see that you are still logged in.
- You can try logging out on the Google page, closing, and reopening to see the logged-out state. Then log back in, close, reopen to see the logged-in state.
- The profile directory (e.g.,
data/browser_automation_profiles/{pipeline_id}/google_session
) should persist on your file system.
This plan provides a structured approach to implementing the requested feature, building upon your existing robust workflow system. Remember to adjust paths, variable names, and logic as needed to perfectly fit into your evolving codebase. Good luck!
End of Day Update, Update From Claude
Reporting in at 9:00 PM and persistence achieved! Here’s the update from Claude 3.7 Sonnet.
Claude: I’ll expand the article with more technical depth and fascinating details about our implementation journey. Here’s the enhanced version:
The Evolution of Browser Automation: From Ephemeral to Persistent Sessions
The original article discussed the transition from stateless to stateful web applications, drawing parallels to the evolution of AI systems. Our implementation of browser automation in Pipulate provides a perfect case study of this evolution in action, particularly in how we handle session persistence. What started as a simple URL opener evolved into a sophisticated system that bridges the gap between ephemeral and persistent states, all while maintaining a clean, user-friendly interface.
The Implementation Journey: From Simple to Sophisticated
Our browser automation workflow began with two foundational steps that laid the groundwork for more complex functionality:
- Step 1: The Ephemeral URL Opener
- A simple demonstration of Selenium’s basic capabilities
- Created temporary profiles that were discarded after each session
- Used Chrome’s
--user-data-dir
with a temporary directory - Demonstrated the “fire-and-forget” nature of basic browser automation
- Step 2: The Data-Preserving Crawler
- Built on Step 1’s foundation but added data persistence
- Used selenium-wire to capture network traffic
- Saved response headers, source HTML, and rendered DOM
- Maintained the ephemeral nature of browser sessions
- Created a foundation for more complex automation tasks
The real breakthrough came with Steps 3 and 4, where we implemented a sophisticated session persistence system that demonstrates the evolution from ephemeral to persistent states.
The Profile Management Evolution
Our initial approach to profile management was overly complex, creating pipeline-specific profiles:
# Initial, overly complex approach
def _get_selenium_profile_paths(self, pipeline_id: str, desired_profile_leaf_name: str = "google_session") -> tuple[str, str]:
from pathlib import Path
safe_pipeline_id = "".join(c if c.isalnum() or c in ('-', '_') else '_' for c in pipeline_id)
user_data_root_for_pipeline = Path("data") / self.app_name / "selenium_user_data" / safe_pipeline_id
user_data_root_for_pipeline.mkdir(parents=True, exist_ok=True)
return str(user_data_root_for_pipeline), desired_profile_leaf_name
This approach had several issues:
- Created unnecessary profile proliferation
- Complicated the user experience
- Violated the single-tenant nature of the application
- Made session management more complex than necessary
We evolved to a simpler, more correct approach:
# Final, simplified approach
def _get_selenium_profile_paths(self, pipeline_id: str, desired_profile_leaf_name: str = "google_session") -> tuple[str, str]:
from pathlib import Path
user_data_root = Path("data") / self.app_name / "selenium_user_data"
user_data_root.mkdir(parents=True, exist_ok=True)
return str(user_data_root), "google_session"
This evolution brought several benefits:
- One user = One profile
- Shared profile across all pipeline instances
- No profile proliferation
- Cleaner directory structure
- More intuitive for a single-tenant local app
The Session Persistence Implementation
The core of our session persistence implementation lies in how we manage browser profiles and handle user interactions:
async def step_03_submit(self, request):
# ... initialization code ...
chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument(f"--user-data-dir={profile_dir_path}")
# Add stealth options to avoid detection
chrome_options.add_argument("--disable-blink-features=AutomationControlled")
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
chrome_options.add_experimental_option("useAutomationExtension", False)
driver = webdriver.Chrome(service=service, options=chrome_options)
# Execute CDP commands to prevent detection
driver.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {
"source": """
Object.defineProperty(navigator, 'webdriver', {
get: () => undefined
});
Object.defineProperty(navigator, 'plugins', {
get: () => [1, 2, 3, 4, 5]
});
Object.defineProperty(navigator, 'languages', {
get: () => ['en-US', 'en']
});
"""
})
Key technical innovations in this implementation:
- Stealth Mode Implementation
- Disabled automation flags
- Added CDP commands to mask automation
- Prevented detection by anti-bot systems
- Maintained a natural browser environment
- Profile Management
- Single profile per user
- Persistent storage location
- Clean separation of ephemeral and persistent states
- No profile proliferation
- User Interaction Flow
- Manual browser closure
- State preservation between sessions
- Clean session management
- Intuitive user experience
The User Experience Evolution
The user interface evolved to provide a seamless experience while maintaining technical robustness:
async def step_03(self, request):
# ... initialization code ...
if profile_action == "reopen":
button_label = "Open Google Again"
instructions = "Click the button to reopen Google.com. You should see your previous login session."
else:
button_label = "Open Google & Log In"
instructions = "Click the button to open Google.com. Please log in with your Google account."
return Div(
Card(
H3(step.show),
P(instructions),
P("Note: This profile will be cleared when the server restarts.",
style="color: #666; font-style: italic;"),
Form(
Button(button_label, type="submit", cls="primary"),
Input(type="hidden", name="profile_action", value=profile_action),
hx_post=f"/{app_name}/{step_id}_submit",
hx_target=f"#{step_id}"
)
),
Div(id=next_step_id),
id=step_id
)
The UI improvements include:
- Clear instructions for users
- Visual feedback on session state
- Intuitive button labels
- Informative notes about profile persistence
- Seamless integration with workflow patterns

This achievement in browser automation serves as a perfect example of how modern web technologies can be combined with thoughtful implementation patterns to create powerful, user-friendly tools. It’s a testament to the importance of evolving from simple solutions to sophisticated systems while maintaining clean, maintainable code and intuitive user experiences.
The implementation also demonstrates the value of iterative development, where we started with a simple solution and evolved it into a more sophisticated system while maintaining clean code and intuitive user experiences. This approach allows for continuous improvement while ensuring that the system remains maintainable and user-friendly.

Strengths (for Future Book):
- Authentic Problem-Solving: Provides a real-time, first-person account of tackling a common and often tricky technical challenge (session persistence).
- Detailed Technical Insights: Includes specific code snippets (Python with Selenium), configuration details (Chrome options, user data directories), and debugging thought processes, especially in the “Claude” section.
- Evolution of a Solution: Clearly shows the iterative development process, including the refinement of profile management strategies.
- Contextual Richness: The author connects the immediate technical problem to broader concepts like “deliverable-makers,” the history of web application statefulness (CGI vs. Active Server Pages), and the role of AI in development.
- Practical Application: Demonstrates the “why” behind the “how,” linking the technical solution to practical benefits for SEO consultants and workflow automation.
- Identification of Anti-Detection Techniques: The inclusion of stealth options and CDP commands for Selenium is a valuable, advanced topic.
Weaknesses (for Future Book):
- Raw Journal Format: The content is a “brain dump” mixed with AI interactions, requiring significant structuring, editing, and curation to become a coherent book chapter.
- Jargon and Assumed Knowledge: Relies heavily on terms and project names (Pipulate, Botify, NixOS, specific AI models) that would be unfamiliar to a general tech audience without extensive glossaries or introductions.
- Internal Monologue vs. Public Exposition: The narrative often reads as personal notes rather than material explicitly written to teach or explain concepts to others.
- Repetitive Elements: Some concepts are revisited multiple times as the author works through them, which is natural for a journal but would need streamlining.
- Uneven Detail: Some parts are highly detailed (Selenium options), while others are more high-level ideas that were ultimately deferred.
- Lack of Visuals/Diagrams: A book chapter would benefit from diagrams illustrating concepts like profile management, workflow steps, or system architecture.
- Needs Clearer Pedagogy: To be effective in a book, it needs defined learning objectives, summaries of key takeaways for each section, and possibly exercises or review questions.
AI Opinion (on Value for Future Book): This journal entry collection is exceptionally valuable as raw material for a tech book, particularly one focused on practical software development, browser automation, or the evolving landscape of AI-assisted coding. Its strength lies in its authenticity and the detailed chronicle of a developer’s thought process, from initial brainstorming and prioritization to deep technical problem-solving and iterative refinement. The inclusion of direct interactions with AI and reflections on their utility adds a contemporary and relevant layer.
However, its current “journal format” means it’s not directly usable as a book chapter. It requires substantial editorial work: structuring the narrative, explaining jargon and prerequisite concepts, extracting the core technical lessons into a more digestible format, and removing conversational or overly personal elements not relevant to a broader audience. The “End of Day Update from Claude” section shows a glimpse of how this raw material can be transformed into a more structured and explanatory piece. With careful curation, this content can form the basis of a compelling and insightful chapter or case study.
