mod_proxy map http://myserver/game to http://localhost:5732/?

  • 772

N00b question. I have an URL

 http://myserver.com/game

and would like to call an internal resource

 http://localhost:5732/

I tried:

AllowCONNECT 5732
ProxyPass /game/ http://localhost:5732/ nocanon
ProxyPassReverse /game/ http://localhost:5732/

but the HTML coming back contained links that didn't get /game/ prepended and JS and CSS broke. So I tried:

 RewriteEngine On
 RewriteRule ^/game(.*) http://localhost:5732$1

but that sends a redirect (which of course doesn't work) to the browser.

What do I get wrong? My goal is:

 http://myserver/game --> http://localhost:5732/

Help is greatly appreciated

    If your Apache version is recent enough (2.4+), you can try mod_proxy_html

    ProxyPass /game http://localhost:5732 nocanon
ProxyPassReverse /game http://localhost:5732
<Location /game/>
    ProxyHTMLEnable On
    ProxyHTMLURLMap / /game/
</Location>

    For older versions of apache, you can try with mod_substitute. However, this requires you to manually write your regexes. This could be a starting point:

    ProxyPass /game http://localhost:5732 nocanon
ProxyPassReverse /game http://localhost:5732
<Location /game/>
    SetOutputFilter SUBSTITUTE
    Substitute s|href='/|href='/game/|nq
    Substitute s|src='/|src='/game/|nq
</Location>

    Of course, the exact configuration will depend on what output you currently get from your game server.

  2. The first version you did, with ProxyPass and ProxyPassReverse, is the most common way to do what you want. The problem is that whatever it is you've got running on localhost:5732 is the thing that creates the HTML that will be sent back - and it doesn't know that it's not called localhost:5732. Your proxypass doesn't change the pages that are passed through, it so if your game contains all the wrong links, that's what you'll see.

    So, to make this work, you need to reconfigure your game thingy so it knows to present its links etc as your.server/game instead of localhost.5732.
