1. ✅ HTTPS Detection Fixed (session.go:723)
- Now uses X-Forwarded-Proto header instead of r.URL.Scheme
- Properly detects HTTPS in reverse proxy environments
2. ✅ SameSite Cookie Attribute Fixed
- Removed automatic SameSiteStrictMode for HTTPS (would break OAuth)
- Keeps SameSiteLaxMode to allow OAuth callbacks from external domains
- Only uses Strict for AJAX requests which don't involve OAuth redirects
3. ✅ Cookie Domain Handling Fixed
- Now respects X-Forwarded-Host header for cookie domain
- Ensures cookies are set for the public domain, not internal proxy domain
4. ✅ EnhanceSessionSecurity Properly Integrated
- Function is now actually called during session save
- Applies security enhancements without breaking OAuth flow
Why Issue #53 Failed Before:
1. Cookies were not marked Secure in HTTPS environments (browser wouldn't send them back)
2. If they had been Secure with SameSite=Strict, Azure callbacks would still fail
3. Cookie domain might have been wrong (internal vs public domain)
Why It Works Now:
1. Cookies are properly marked Secure for HTTPS
2. Uses SameSite=Lax to allow OAuth provider callbacks
3. Cookie domain uses public domain from X-Forwarded-Host
4. CSRF token persists through the entire OAuth flow
- Optimise the errors and recovery.
- Deduplicate code in metadata cache.
- Remove unused performance monitoring code.
- Simplify session management and settings handling.
