I have some subdomains I want to redirect to specific ports on the same server. Say I have


I want dev.mydomain.com to redirect to mydomain.com:8080 how do I do this with Apache 2.2? I have Apache 2.2 running on default port 80. I can't figure out the write configuration to get this to happen.

I also want to keep the dev.mydomain.com in the URL of the client. I don't anyone to realize it is actually being hosted on a different port, this part is very important.

I have already set up dev.mydomain.com to resolve in DNS to mydomain.com, I want all the request to preserve the subdomain in the address bar of the browser.

This is for an intranet development server so I am not so concerned about exploits and security. This is server has a non-routable ip address as well.

do you want to see your client that it is being redirected or do you want it to seem as if everything is running on dev.mydomain.com port 80? –  Marcel G Oct 28 '10 at 15:17
everything on port 80 –  Jarrod Roberson Feb 17 '11 at 22:33

Here is what I finally came up with after being set in the right direction by Miles Erickson. I wanted the address bar to reflect the original subdomain/domain of the request and not the redirected server and port, but he put me on the right path to Google up a solution using VirtualHost and I finally found a solution that included the use of mod_proxy.

NameVirtualHost *:80

<VirtualHost *>
    ServerAdmin me@mydomain.com
    ServerName dev.mydomain.com
    ProxyPreserveHost On

    # setup the proxy
    <Proxy *>
        Order allow,deny
        Allow from all
    ProxyPass / http://localhost:8888/
    ProxyPassReverse / http://localhost:8888/

Looks like a great solution. –  Skyhawk Oct 29 '10 at 20:46
Thanks - this also worked for me - after searching for a long time. –  DominikAngerer Jan 8 at 22:03

Assuming that dev.mydomain.com can be resolved to mydomain.com's IP, you could add the following to your httpd.conf:

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName dev.mydomain.com
    redirect / http://mydomain.com:8080/

Relevant Apache documentation:

  1. Guide to creating name-based virtual hosts
  2. Core, including VirtualHost and NameVirtualHost
  3. Redirect

Related question: Apache redirect based on hostname

(Note: the original version of this answer incorrectly suggested the use of RedirectMatch, which, as @ChrisS helpfully pointed out, cannot parse the domain portion of the URL.)

see my self provided answer for what I actually used, which is this idea of VirtualHost with mod_proxy to preserve the original host instead of doing a redirect. This is an internal server so I am not concerned with security or exploits of mod_proxy. –  Jarrod Roberson Oct 28 '10 at 15:38
Found numerous other suggestions but this ultimately worked for me on Windows Server 2008 R2/Apache 2.2.25. –  HPWD Jul 12 at 20:07

Add in your main vhost configuration the following lines:

ProxyPreserveHost On
ProxyPass / http://example.com:8080/
ProxyPassReverse / http://example:8080/

Note that this requires mod_proxy on Apache.

This is not a redirect; it proxies the connection. Enabling mod_proxy can be extremely easy to exploit if you aren't very careful configuring it. I would highly recommend against this. –  Chris S Oct 28 '10 at 12:38
He doesn't want a redirect, as per his OP. He wants the original URL to remain in the address bar; this means using either mod_proxy or mod_rewrite, and y'all better avoid mod_rewrite. –  adaptr Mar 1 '12 at 14:40

You're looking for mod_rewrite. Here's the link to Apache's documentation which includes many examples for basic and advanced configurations..

And if you're unable to interpret the documentation yourself, try adding this to httpd.conf:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^dev\.example\.com$ [NC]        
RewriteRule ^(.*)$ http://example.com:8080$1 [R=301]    

And if that's not a clear example, here's a link to a mod_rewrite beginners guide too.

It isn't correct. mod_rewrite should only be used as a last resort, when nothing else will do. The redirect and proxy solutions given are far superior in this (and almost any other conceivable) case. –  adaptr Mar 1 '12 at 14:38
@adaptr This does a redirect, I fail to see how any of the other redirects are "far superior". And suggesting that he setup a proxy when he clearly doesn't have a firm grasp of Apache/Security/Performance/etc, is that serious? –  Chris S Mar 1 '12 at 15:28
