Websocket reverse proxy with apache2

I solved this by using nginx instead. Thanks for sample apache config.

Just a little side note: it does not work for the live reload socket, because that one does not use the /socket/ path, and thus falls through over HTTP. I have not found a fix for that, yet.

I accidentally removed my solution. So here it is, again:

<VirtualHost *:80>
    ServerName example.com
    ErrorDocument 404 /404.html
    ServerAdmin admin@example.com

    ProxyPass        /socket/ ws://myapp.com:8000/socket/
    ProxyPassReverse /socket/ ws://myapp.com:8000/socket/

    ProxyPass        / http://myapp.com:8000/
    ProxyPassReverse / http://myapp.com:8000/

</VirtualHost>

The example assumes your Apache reverse proxy is running on example.com, and your application is running on myapp.com with port 8000 published.

Just a little side note: it does not work for the live reload socket, because that one does not use the /socket/ path, and thus falls through over HTTP. I have not found a fix for that, yet.

One of the main point is to use the domain name, IIRC. And also correct socket path

This final configuration worked for me including live and live reload

<VirtualHost *:80>
    ServerName myserver.com

   RewriteEngine on
   RewriteCond %{HTTP:Upgrade} websocket [NC]
   RewriteCond %{HTTP:Connection} upgrade [NC]
   RewriteRule ^/?(.*) "ws://localhost:4000/$1" [P,L]

   ProxyPass        /socket/ ws://localhost:4000/socket/
   ProxyPassReverse /socket/ ws://localhost:4000/socket/

   ProxyPass        /live/ ws://localhost:4000/socket/
   ProxyPassReverse /live/ ws://localhost:4000/socket/

   ProxyPass        / http://localhost:4000/
   ProxyPassReverse / http://localhost:4000/

</VirtualHost>
