Debugging WebSocket Issues Behind mod_proxy_wstunnel
When setting up a WebSocket server behind Apache with mod_proxy_wstunnel, users may encounter difficulties. To debug these issues effectively, it's essential to examine the following:
Request Routing:
- Ensure that the ProxyPass directive for the WebSocket path (/ws/) is ordered before the general / ProxyPass.
Trailing Slash:
- Add a trailing slash to the WebSocket path configuration, as mod_proxy_wstunnel expects a valid GET request with a URL-encoded path.
Origin Check:
- If the WebSocket server includes an origin check, such as in the ServeWs() function of the Chat example, remove it to prevent conflicts with mod_proxy_wstunnel.
Additional Debugging Tips:
- Consult the server logs to identify any specific error messages that can provide insights into the problem.
- Verify that the WebSocket server is running on the correct port and is accessible via SSH tunnels.
The above is the detailed content of How to Debug WebSocket Problems with Apache's mod_proxy_wstunnel?. For more information, please follow other related articles on the PHP Chinese website!
Golang vs. Python: Concurrency and MultithreadingApr 17, 2025 am 12:20 AMGolang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.
Golang and C : The Trade-offs in PerformanceApr 17, 2025 am 12:18 AMThe performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.
