Proxy websocket wss:// to ws:// apache

Question

i searched alot but i couldnt connect my websocket to wss:// , i found that there is a way to proxy wss://domain.com:9090 and apache apply the proxy on it and redirect request

Answer 1

You need to enable some Apache2 modules:

$ a2enmod proxy proxy_wstunnel proxy_http rewrite

Then you can use this configuration to solve your problem.

    ProxyRequests off
    ProxyVia on      
    RewriteEngine On

    RewriteEngine On
    RewriteCond %{HTTP:Connection} Upgrade [NC]
    RewriteCond %{HTTP:Upgrade} websocket [NC]
    RewriteRule /(.*) ws://example.com:9090/$1 [P,L]

    ProxyPass               /websocket http://example.com:9090/websocket
    ProxyPassReverse        /websocket http://example.com:9090/websocket

Apache2 automatically upgrades the connection to websocket with ws://, you don't need to set the ws:// manually. I tried dozens of configurations and this is the only one that worked for me.
