Fix CAPTCHA and Cloudflare verification by preserving credentials and request properties

[Copilot]

CAPTCHA verification (reCAPTCHA, hCaptcha, Cloudflare Turnstile) was failing due to cookies being rejected and requests losing credentials when proxied.

Root Causes

Service Worker (sw.js)

• Request mode was being overridden (navigate → same-origin), breaking cookie handling
• Enhanced CAPTCHA requests weren't passed to proxy handlers (UV/Scramjet)
• Critical headers (Referer) and properties (cache, redirect) weren't preserved

CAPTCHA Handler (captcha-handler.ts)

• Only handled reCAPTCHA cookies (_GRECAPTCHA), ignoring hCaptcha and Cloudflare
• Cookie descriptor modification lacked browser compatibility checks
• XHR credentials weren't forced for CAPTCHA domains
• Incomplete CAPTCHA domain detection (missing cdn-cgi, cf-assets)

Changes

sw.js

• Preserve request mode, cache, and redirect properties
• Pass enhanced requests through proxy by creating modified events:

if (isCaptcha) {
    const modifiedEvent = Object.create(event);
    modifiedEvent.request = request;
    return await uv.fetch(modifiedEvent);
}

• Add Referer header preservation
• Expand CAPTCHA domain list

captcha-handler.ts

• Support all CAPTCHA cookie types: _GRECAPTCHA, _hcaptcha, cf_clearance, __cf_bm
• Add configurable check and error handling for cookie descriptor
• Force credentials: "include" for all CAPTCHA requests (handle "omit" case)
• Properly type XMLHttpRequest overrides to fix TypeScript errors

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• telemetry.astro.build
  • Triggering command: node /home/REDACTED/work/Radius/Radius/node_modules/.bin/astro build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

fix cloudflare varfication and fix captias, aspecialy re captia. check if the request are workind or if the cookies are being rejected.
