Worked on the golang/go repository to enhance HTTP server robustness by implementing a LimitedReader for CONNECT requests, capping proxied reads based on MaxResponseHeaderBytes to mitigate memory exhaustion risks. Addressed a critical ServeMux bug by ensuring that empty URL paths in CONNECT requests no longer trigger unnecessary redirects, improving request handling accuracy. The work involved backend development and network programming in Go, with a strong emphasis on API design and comprehensive testing. Updated and added tests validated the new behavior, ensuring reliability and security for HTTP servers handling CONNECT requests. The contributions focused on practical solutions to real-world server vulnerabilities.
