ProxyWebsocketIdleTimeout Directive ¶

+

+Description:Sets the maximum amount of time to wait for data on the websockets tunnel

+Syntax:ProxyWebsocketIdleTimeout num[ms]

+Default:ProxyWebsocketIdleTimeout 0

+Context:server config, virtual host

+Status:Extension

+Module:mod_proxy_wstunnel

+

+    
This directive imposes a maximum amount of time for the tunnel to be

+    left open while idle. The timeout is considered in seconds by default, but

+    it is possible to increase the time resolution to milliseconds

+    adding the ms suffix.
