2023-10-11reverseproxy: Add more debug logs (#5793)Matt Holt
* reverseproxy: Add more debug logs This makes debug logging very noisy when reverse proxying, but I guess that's the point. This has shown to be useful in troubleshooting infrastructure issues. * Update modules/caddyhttp/reverseproxy/streaming.go Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Update modules/caddyhttp/reverseproxy/streaming.go Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Add opt-in `trace_logs` option * Rename to VerboseLogs --------- Co-authored-by: Francis Lavoie <lavofr@gmail.com>

2023-02-06reverseproxy: Log status code and byte count for websockets (#5140)WeidiDeng
* log response size for websocket request * record size when using hijack bufio.Writer

* reverseproxy: Mask the WS close message when we're the client * weakrand * Bump golangci-lint version so path ignores work on Windows * gofmt * ugh, gofmt everything, I guess
2022-09-02reverseproxy: Close hijacked conns on reload/quit (#4895)Matt Holt
* reverseproxy: Close hijacked conns on reload/quit We also send a Close control message to both ends of WebSocket connections. I have tested this many times in my dev environment with consistent success, although the variety of scenarios was limited. * Oops... actually call Close() this time * CloseMessage --> closeMessage Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Use httpguts, duh * Use map instead of sync.Map Co-authored-by: Francis Lavoie <lavofr@gmail.com>
2022-08-02chore: Bump up to Go 1.19, minimum 1.18 (#4925)Francis Lavoie
2022-04-11reverseproxy: Sync up `handleUpgradeResponse` with stdlib (#4664)Francis Lavoie
* reverseproxy: Sync up `handleUpgradeResponse` with stdlib I had left this as a TODO for when we bump to minimum 1.17, but I should've realized it was under `internal` so it couldn't be used directly. Copied the functions we needed for parity. Hopefully this is ok! * Add tests and fix godoc comments Co-authored-by: Matthew Holt <mholt@users.noreply.github.com>
2021-08-12reverseproxy: Incorporate latest proxy changes from stdlib (#4266)Francis Lavoie
I went through the commits that touched stdlib's `reverseproxy.go` file, and copied over all the changes that are to code that was copied into Caddy. The commits I pulled changes from: - https://github.com/golang/go/commit/2cc347382f4df3fb40d8d81ec9331f0748b1c394 - https://github.com/golang/go/commit/a5cea062b305c8502bdc959c0eec279dbcd4391f - https://github.com/golang/go/commit/ecdbffd4ec68b509998792f120868fec319de59b - https://github.com/golang/go/commit/21898524f66c075d7cfb64a38f17684140e57675 -https://github.com/golang/go/commit/ca3c0df1f8e07337ba4048b191bf905118ebe251 - https://github.com/golang/go/commit/9c017ff30dd21bbdcdb11f39458d3944db530d7e This may also fix https://github.com/caddyserver/caddy/issues/4247 because of the change to `copyResponse` to set `mlw.flushPending = true` right away.
