v0.3.0 - Full Nginx Proxy Compatibility

WolfProxy v0.3.0

🎉 Major Release - Full nginx proxy compatibility for OpenSim/Firestorm!

Key Fixes

• Fixed proxy_set_header parsing - Properly strips quotes from header values

  • proxy_set_header Connection ""; now works correctly

• Empty header handling - Empty values (e.g., Connection "") now correctly omit the header entirely instead of sending an invalid empty header

• HTTP/1.1 version - Explicitly sets HTTP/1.1 for proxy requests to match nginx behavior

• Content-Length handling - Skips original content-length header, lets hyper calculate it from the actual body

• Improved HTTP connector - Added TCP nodelay and keepalive settings for better performance

Compatibility

• ✅ Tested with Firestorm viewer login to OpenSim grid
• ✅ Full compatibility with nginx proxy_set_header directives
• ✅ Supports $http_host, $remote_addr, $proxy_add_x_forwarded_for, $scheme variables

• Added install.sh - Automated installation script that:

  • Detects OS and installs build dependencies
