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

问题:

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 to where the normal ws://domain.com:9090 server is running

ProxyPass /websocket ws://domain.com:9090
ProxyPassReverse /websocket ws://domain.com:9090

this code in apache config will send request from any address ended with /websocket to ws://domain.com:9090 ex : ws://websocket will be ws://domain.com:9090

i want to do it for wss:// also ex wss://websocket must point to ws://domain.com:9090

it dosnt work and i get this error in browser console :

failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

is there any mistake here ? thanks you .

i worked 24 hours for find this and searched a lot of forum but no one write about success. here is my server configuration :

CentOS release 6.7 , Apache 4.2.18

here is what i did finally : first i found that modules/mod_proxy_wstunnel.so must be enable in apache config file , but my apache didn't have that module and after a lot of search i found that module is Available in apache 2.4.5 and later.

https://httpd.apache.org/docs/2.4/mod/mod_proxy_wstunnel.html

i downloaded https://archive.apache.org/dist/httpd/httpd-2.4.18.tar.gz extracted httpd-2.4.18\modules\proxy\mod_proxy_wstunnel.c and uploaded to my server root then from terminal could compile it again with these commonds :

chmod 755 mod_proxy_wstunnel.c #set permission
pxs -i -a -c mod_proxy_tunnel.c #compile module

pxs command did compile the module and wrote in apache config file to load it

LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so

after that i added these lines to end of apache config file :

RewriteEngine on
ProxyRequests Off
ProxyPreserveHost on
ProxyPass /myws ws://mysite.com:8091
ProxyPassReverse /myws ws://mysite.com:8091

AND NOW : it works ! in client side js you can set ws url like this :

var protocol = 'ws://'; 
if (window.location.protocol === 'https:') {
            protocol = 'wss://';
   }

 var wsUri =protocol+ "mysite.com/myws";  

 var ws = new WebSocket(wsUri);

and it will forward request to ws://mysite.com:8091 doesnt matter the page loaded with https or http , it will direct all request ended with /myws to ws://mysite.com:8091
