How To Host Multiple Websites by using mod proxy

Using mod_proxy you can map a domain to a sub-directory of Radiant, this can be used to host multiple websites without having to modify Radiant. Your Radiant page tree should be set up like this:

 Site Root
 |
 +- radiantpoweredwebsite.com
 |  |
 |  +- Home
 |     |
 |     +- Subpage 1
 |     |
 |     +- Subpage 2
 |
 +- billa.co.nr
    |
    +- Home
       |
       +- Subpage 1
       |
       +- Subpage 2

With Apache and mod_proxy, you would set up domains like:

 <VirtualHost ServerIP:80>
 ServerName www.radiantpoweredwebsite.com
 ProxyPass / http://www.yourradiantinstall.com/radiant/radiantpoweredwebsite-com/home/
 </VirtualHost>

 <VirtualHost ServerIP:80>
 ServerName www.anotherwebsite.com
 ProxyPass / http://www.yourradiantinstall.com/radiant/anotherwebsite-com/home/
 </VirtualHost>

Note: while the above approach can work, the urls for tags such as link will not be correct. An alternative approach is to use the virtual_domains extension. If using this extension, ProxyPass directly to the root of your radiant install, not the subdirectory. i.e.:

 <VirtualHost ServerIP:80>
 ServerName www.anotherwebsite.com
 ProxyPass / http://www.yourradiantinstall.com/radiant
 </VirtualHost>
