Enhanced Proxy Obfuscation for Bypassing Advanced Detection

Description

Proxyman is currently unable to intercept traffic from many modern websites and services due to their advanced proxy detection mechanisms. Even with SSL decryption disabled, these sites return ETIMEDOUT errors (e.g., PROXY_TO_SERVER_REQUEST_ERROR: Error: connect ETIMEDOUT 104.18.41.116:443). This critical limitation is preventing many users from utilizing Proxyman for legitimate development and debugging purposes.

Why this feature/change is important?

• Critical for Modern Web Development: With Cloudflare protecting >20% of websites and HSTS becoming standard, this isn't an edge case - it's affecting daily workflows for thousands of developers.

• Revenue Impact: Premium users expect comprehensive debugging capabilities. When they encounter these limitations, they question the value proposition compared to alternatives that work more reliably.

• Technical Credibility: As more sites implement security measures like JA3 fingerprinting and strict HSTS, Proxyman risks appearing technically outdated if it can't adapt.

• Genuine Development Use Case: This isn't about circumventing security - it's about allowing legitimate debugging for developers working on their own applications and services.

The specific technical enhancements needed:

1. TLS fingerprinting evasion: Implement browser-like TLS fingerprints
2. HTTP header normalization: Prevent proxy-revealing headers
3. TCP/IP parameter adjustments: Match browser network signatures
4. Advanced bypass system: Create granular controls for problematic domains

No files, tests, or entry points are named. Start by reproducing the reported ETIMEDOUT behavior and map the proxy's handling of TLS fingerprints, HTTP headers, TCP/IP parameters, and per-domain controls. Done would require an agreed design, implementation, and tests demonstrating compatibility without breaking normal proxy behavior.
