⚡ Passing Cloudflare `cf_clearance` Across Python `curl_cffi` Workers (Exact IP + UA Binding)

TU
turnstile_solver OP / ELITE MEMBER
Remember that a solved `cf_clearance` cookie is cryptographically bound to two things: the **exact egress IP address** and the **exact `User-Agent` + `Sec-CH-UA` string** that solved the challenge. Pass both from your Xvfb solver to your `curl_cffi` worker using the same sticky proxy session!

Also make sure the TLS cipher suite order in `curl_cffi` (`impersonate="chrome124"`) matches the Chromium version running in your Xvfb Turnstile solver!

We cache `(cf_clearance, proxy_ip, user_agent)` tuples in Redis with a 25-minute TTL and share them across 50 fast HTTP workers.
