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


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.gzextracted httpd-2.4.18\modules\proxy\mod_proxy_wstunnel.c and uploaded to my server rootthen from terminal could compile it again with these commonds :

chmod 755 mod_proxy_wstunnel.c #set permissionpxs -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 onProxyRequests OffProxyPreserveHost onProxyPass /myws ws://mysite.com:8091ProxyPassReverse /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:8091doesnt matter the page loaded with https or http , it will direct all request ended with /myws to ws://mysite.com:8091


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.
