Apache – Check which virtual host routes a response

Try:

DocumentRoot "C:/store/"

<Directory />
    ....
    RewriteEngine on
    RewriteCond %{REMOTE_HOST}  ^www.domain1.com$
    RewriteRule (.*)$ /www.domain1.com/$1 [L]

    RewriteCond %{REMOTE_HOST}  ^www.domain2.com$
    RewriteRule (.*)$ /www.domain1.com/$1 [L]
</Directory> 

Alias /admin C:\cms\admin

<Directory "C:\cms\admin">
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory> 

This may be obvious, but don't forget to restart the apache service after enabling additional virtual host.

After executing a2ensite for the second virtual host, the output of apache2ctl -S reflects that both sites are configured (and one of them is the default), but it won't be live until you reload apache.

Let's say you have two virtual hosts - site1 and site2. You run a2ensite site1 and then reload apache service. Now you can access http://site1 and it is the default. Now you run a2ensite site2, but forget to restart apache. The output of apache2ctl -S will be:

VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:80                   is a NameVirtualHost
         default server site1 (/etc/apache2/sites-enabled/site1:1)
         port 80 namevhost site1 (/etc/apache2/sites-enabled/site1:1)
         port 80 namevhost site2 (/etc/apache2/sites-enabled/site2:1)
Syntax OK

But when you try to load http://site2, it will actually load the default site (site1), since the configuration isn't loaded.
