Executing PHP files when called via AJAX from another domain

Hello,

I have set up a standard cgi/php/static application that is based on a core set of PHP files. It is based on AJAX calls to these php files that provide dynamic content for each 'page'.

The application is such that multiple versions of this 'website' are configured with a few different scripts contained in subfolders contained within this application, that also contain a new index.php page;

i.e each new folder with configuration files = A new 'website' based on core files that comunicate with the configuration scripts.

As a result of this behaviour, it is preferable to give each of the 'websites' a different domain. This can be achieved by creating a symbolic link app and directing it to the index.php file in the configuration folder.

However, the server will not execute the php code in the core file folder when it is called cross domain! It will deliver any static pages of javascript files or resources like images, but the server will not process any php code.

I have tried adding;

header("Access-Control-Allow-Origin: *");

But to no avail,

Thanks in advance,

Hugh
