Hi, we recently stumbled over the missing WebSocket support in pound. I attached a patch against vanilla pound-2.8 which adds support. So far it has been tested with Guacamole (https://guacamole.apache.org/) and with a commercial product using WebSockts and it worked without any problems or side effects. The patch collects the various markers for an upgrade request and for the server`s acceptance of the upgrade in variable "is_ws". When all markers have been collected, the connection switches to "WebSocket mode", i.e. simply forward everything between client and server in both directions until the connection is closed or times out. There is no parsing of WebSocket frames. With the patch, WebSockets should start working out of the box. There's no need to configure anything special (except for the usual listener, service and backend configuration of course). WebSocket connections are usually long-lived (hours or even days). However WebSocket clients usually send keep alive packets to prevent timeouts or silently re-connect when the connection is closed. So I decided to use a rather conservative timeout of just 600 seconds. You can override this default with the new configuration file directive "WSTimeout <seconds>" on the global level and per backend. Regards, Frank
