apache2 configuration for blog.example.com not working

Question

I have my blog running at a server with ip 10.10.10.10(not real).

There is only one virtual host for this blog on the server.

Here is the apache configuration:

VirtualHost star:80
ServerName blog.example.com
ServerAlias blog.example.com
ServerAdmin [email protected]
DocumentRoot /var/www/
RewriteEngine on
RewriteCond %{HTTP_HOST} ^[^.]+.example.com$
RewriteRule ^(.+) %{HTTP_HOST}$1 [C]
RewriteRule ^([^.]+).example.com/(.*) /var/www/$1
DirectoryIndex index.php

Directory /var/www/ AllowOverride All
Order Deny,Allow
Allow from all
/Directory
/VirtualHost

My DNS blog.example.com is pointing to this ip address 10.10.10.10 .

When I load first time blog.example.com it loads correct with no problems. But whenever i click a link it shows url like http://10.10.10.10/login.php etc.

I am a newbie. Please help me set up this.
Is there any problem with the rewrite rule ?

Answer 1

The problem is the application generating URLS seems to be creating absolut URIs which your server is unable to handle because of your Server Configuration.

There are two possible solutions which come to mind:

Configure the Application correctly so it either creates relative URIs or if really needed absolute URIs with the correct host.

The dirty solution would be to put a ServerAlias directive in place to handle this:

ServerAlias 10.10.10.10 

It would be possible but not advisable to solve the problem with mod_rewrite as well. But this so terrible style I won't explain it.
