How to rewrite / proxy an Apache URI to an application listening on a specific port / server?

Question

They say that Apache\'s mod_rewrite is the swiss-army knife of URL manipulation, but can it do this?

Lets say I want to add a new application to my Apache webserver,

Answer 1

Using mod_proxy would work just fine. For instance, I mapped https://localhost/yalla/ to point to a subdirectory of my webserver:

LoadModule proxy_module modules/mod_proxy.so
ProxyRequests On
<Proxy *>
      Order deny,allow
      Allow from localhost
</Proxy>
ProxyPass /yalla/ http://yalla.ynfonatic.de/tmp/

If you implement this, you'll note that the pictues of the directory-listing aren't visible; this is because they're below the /tmp/ directory on the remote server, hence not visible.

So, in your case you'd do:

LoadModule proxy_module modules/mod_proxy.so
ProxyRequests On
<Proxy *>
      Order deny,allow
      Allow from localhost # Or whatever your network is if you need an ACL
</Proxy>
ProxyPass /app/ http://hostname.example.com:8080/

Like with everything in Apache configuration, watch those trailing slashes when referring to directories.

Good luck! Alex.
