I Need an Advanced Automation Developer – Redirect-Based Booking Bot (Goethe, Wicket Apache, COE Session Handling) For Goethe Booking like Chennai and Bangalore I am looking for a high-level automation/bot developer who has experience with: Wicket/Apache-based web applications Multi-step redirect chains COE session initialization & dynamic token handling ColdFusion (CFID/CFTOKEN) & JSESSIONID flows Cookie extraction & accurate replay of Set-Cookie across redirects Chrome CDP automation / Playwright / Puppeteer High-speed DOM watching (DOMWatcher / MutationObserver) Proxy rotation & session isolation --- Project Goal Build a bot that can open the “Select Modules / Book” page reliably during Goethe exam seat drops, even when: normal browser attempt shows "We are sorry, high demand…" the booking button is visible only for milliseconds the server uses strict Wicket state, session validation, redirect pruning, and timing-based acceptance The bot must reproduce: the exact Chrome behavior, the correct redirect chain starting from the button link, and all intermediate cookies and server state parameters. --- Key Technical Requirements 1. Reproduce full redirect chain From the button link: [login to view URL] The bot must follow all server redirects accurately: /coe?lang=… /coe/?lang=… /entry?lang=…&oid=… /selection?... Final page that shows available modules. 2. Correct handling of all dynamic cookies The bot must automatically extract and reuse: coesessionid COE-Tab-ID COE-Customer CFID / CFTOKEN JSESSIONID SRVCMS5WWW Missing any of these breaks the chain. 3. Accurate reproduction of Chrome headers Including: sec-ch-ua sec-fetch-* Referer Origin Chrome TLS/HTTP2 behavior (via CDP, not simple requests) 4. DOM watcher for instant-click The bot must: run 20–40 parallel isolated sessions detect the green “SELECT MODULES” button in <5 ms click instantly and open the booking page in a real Chrome window 5. Proxy + Session Isolation Each tab/session must run with: separate cookies separate profiles optional proxy separate localStorage separate COE-Tab-ID --- Expected Deliverables 1. Backend module: performs all redirect handling extracts & reconstructs session cookies verifies valid coesessionid 2. Frontend module: opens real Chrome instance loads booking page using backend-generated session triggers instant click shows the booking flow normally for manual payment. 3. Configuration panel (optional) add accounts choose city, exam, time set number of parallel tabs “If my current approach is incorrect, I would like to understand the correct method to handle this system. If you have the expertise, please guide me or help me build a fully functional bot script.” Skills Required Playwright / Puppeteer / Selenium (CDP mode) Strong understanding of HTTP/2, redirects, cookies, CSRF Experience with anti-bot bypasses Experience with Wicket / Java server-side frameworks --- Only Experienced Developers This is not a simple Selenium clicker job. Only message if you have real experience with strict session-based booking systems. Provide: past work samples your approach to solving redirect-based session recreation estimated timeline & cost --- Contact Message me here on Freelancer with: “I understand the Wicket redirect chain” and your past automation experience.

Hello there “I understand the Wicket redirect chain.” I have real experience with session-strict booking systems where redirects, cookies, and timing must be exact. I use real Chrome via CDP (Playwright/Puppeteer) to fully reproduce Chrome headers, HTTP/2 behavior, and the complete redirect chain. I’ll build: Reliable redirect + cookie reconstruction (Wicket-safe) Instant DOM watcher for millisecond button clicks 20–40 fully isolated Chrome sessions (profiles, cookies, optional proxies) Real Chrome window for normal booking and payment flow Timeline: 2 days Focus: fast, stable, production-quality automation — not a fragile clicker. Ready to start immediately.

With over 7 years of successful experience in developing advanced automaton and bot solutions, I believe I am the ideal candidate for your redirect-based booking project. My expertise in using Wicket/Apache, handling multi-step redirects and COE sessions, combined with strong knowledge of Playwright/Puppeteer and Chrome CDP automation, makes me a perfect fit for the task at hand. I have dealt extensively with complex session flows (including CFID/CFTOKEN and JSESSIONID) thus ensuring balanced cookie extraction and pinpointing replay errors. In terms of technical requirements, I understand the need to reproduce a full redirect chain accurately – a task where I excel. Reproduction starting from button links, handling dynamic cookies, accurate replication of Chrome headers - I have done it all before! Additionally, my extensive experience with DOM watching ensures not just parallel sessions but also quick detection of the booking button click within milliseconds. Ensuring session isolation with proxy rotation is a capability that sets my services apart from others. This would help your bot run exponentially faster and without any interference between individual booking processes. Lastly, my skills with both Selenium (CDP mode) and Wicket are in perfect alignment with what your project requires. Give me this opportunity to guide you in building an efficient and fully functional bot script while also maintaining utmost transparency throughout the process.

I have hands-on experience building redirect-based, session-strict booking bots similar to Goethe COE systems, including Wicket/Java backends with ColdFusion and JSESSIONID flows. I can reliably reproduce: Full Wicket redirect chains with state preservation Dynamic cookie extraction & replay (COE session, CFID/CFTOKEN, JSESSIONID) Real Chrome behavior via CDP (Playwright/Puppeteer) High-speed DOM watching for millisecond-level booking clicks Parallel, fully isolated sessions with proxy support Approach: I reverse-engineer the redirect + session initialization first, then generate valid backend sessions that are injected into real Chrome instances for instant DOM-triggered booking—no fragile Selenium clicking. I’ll deliver a stable backend + Chrome automation flow that opens the Select Modules / Book page reliably during seat drops, with clean handoff for manual payment. Timeline: ~2 weeks Happy to share relevant automation samples on request. — WiredAI Ventures

I understand the Wicket redirect chain. I have built many automation bots for websites with Playwright / Puppeteer / Selenium. Specailly I made sportsbetting sites that redirect and protect bot actions. But I all avoided it and placed many bets. I think I can comlete your project with my skills. Thanks.

Your core challenge is reliably bypassing Goethe’s strict, session-dependent booking system to secure exam seats at high-demand moments where milliseconds matter. Failing to replicate exact redirects, cookies, and browser behavior risks session invalidation and missed bookings. My proven approach precisely reconstructs multi-step redirect chains, dynamic tokens, and Chrome-specific headers ensuring seamless session continuity under high load. I’ve delivered complex session-critical automation outside platforms like this, and offer a strategic discounted rate here to build trusted platform presence without compromising quality. Let’s explore your current method and ensure this critical bot executes flawlessly. A brief reply can start clarifying your setup. Liam Jasson

Hello, I understand the Wicket redirect chain and the realities of booking systems like Goethe COE—this is not a Selenium click job, but a stateful, timing-critical session recreation problem. I have hands-on experience with Wicket/Apache applications, ColdFusion-backed sessions (CFID/CFTOKEN), JSESSIONID flows, and strict redirect validation where a single missing cookie or header breaks the chain. I’ve built automation that faithfully reproduces real Chrome behavior via CDP, handling multi-step redirects, dynamic session tokens, and browser-level headers instead of fragile HTTP requests. My approach focuses on: Clean session initialization and redirect-chain integrity Accurate Set-Cookie capture and replay across redirects Parallel, fully isolated browser contexts with optional proxy support Event-driven DOM detection for instant UI interaction Separation of backend session handling and frontend Chrome execution I’m comfortable auditing existing approaches and explaining why they fail, as well as proposing a correct, stable architecture before implementation. Reliability and maintainability matter more than shortcuts in systems like this. I can share relevant automation work, outline my technical approach, and provide a realistic timeline and cost estimate after a brief discussion. If you’re looking for someone who truly understands redirect-based, session-locked booking systems, I’m ready to help.
