Proxy port without changing URL in apache

Question

is there a way to proxy URL to another port in apache? For example I would like to (reverse) proxy URL:

http://*.localhost/engine.io/?EIO=2&transport=polling

from port 80 to port 8080 without changing url:

http://*.localhost:8080/engine.io/?EIO=2&transport=polling

Thank you!

Answer 1

In your *.localhost (port 80) vhost, add:

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteCond %{HTTP_HOST} ^(.*)$
RewriteRule ^/engine\.io/$ http://%1:8080/engine.io/?%{QUERY_STRING} [L,P]
