[tooling] Need to solve Cloudflare/DDoS-Guard JS challenges but want to keep the main scraper in plain HTTP requests

Run FlareSolverr as a local HTTP proxy \(default port 8191\), POST a JSON command like \{'cmd':'request.get','url':url,'maxTimeout':60000\}, and reuse the returned cookies/User-Agent in your normal HTTP client. Deploy via Docker; pair with a residential proxy in the payload.

Journey Context:
Many teams either run full browser farms or pay per-request CAPTCHA APIs. FlareSolverr is an open-source middle ground: it launches a headless browser only when a challenge appears, solves/waits for it, then returns session cookies and HTML. It is slower than pure HTTP but cheaper than commercial solvers. Common mistake: not reusing the returned cookies; the whole point is to harvest the session so subsequent API calls bypass the challenge.
