What's Changed

Fix WebSocket proxy URL construction and missing configuration parameter by @Weixi779 in [#160]

Background

I noticed issue [#147] regarding the incorrect WebSocket proxy URL construction. I also saw a similar solution proposed in PR [#149] by @GEverding, which correctly identified the root cause of the problem.

However, PR [#149] received a change request from @0xTim asking for tests to verify the proxy URI generation. Since that PR has not been updated, I have created this PR with the complete fix including the requested test modifications.

Changes

1. Fix proxy URL construction order - Fixes [#147]

  • Changed URL format from ws://host/path:port to ws://host:port/path
  • Updated test assertion in testProxy to expect the correct URL format
  • Credit to @GEverding for identifying this issue in PR [#149]

2. Add missing configuration parameter

  • Pass configuration parameter when connecting through proxy
  • Ensures client configuration is properly forwarded to the underlying connection

3. Use correct URI form for wss + proxy connections

  • For wss with proxy: use origin-form (/path) after CONNECT tunnel per RFC 7230 …
