one chart for 2 domains alias

[4hjoomla]

Hi,
I'm trying to manage one site with a store and 2 domain alias that reference to the same place.
the first is www.domain1.co.uk  and the second is  www.domain2.co.uk

www.domain1.co.uk  is the main domain and the cart work wel without ant problems.

but when im runing the site under the second domain (www.domain2.co.uk ) the cart is not working well and i got this error:

XMLHttpRequest cannot load http://www.domain1.co.uk/index.php. Origin http://www.domain2.co.uk  is not allowed by Access-Control-Allow-Origin.


1) I change the virtuemart.php.cfg file

Code: [Select]

if ($_SERVER['HTTP_HOST'] == "www.domain2.co.uk/") {
define( 'URL', 'http://www.domain2.co.uk/' );
define( 'SECUREURL', 'https://www.domain2.co.uk/' );
} else {
define( 'URL', 'http://www.domain1.co.uk/' );
define( 'SECUREURL', 'https://www.domain1.co.uk/' );
}

2) change htacsses like the sample http://docs.joomla.org/Multiple_Domains_and_Web_Sites_in_a_single_Joomla!_installation

Code: [Select]

#The following rule works, but it changes which domain name displays.
RewriteCond %{HTTP_HOST} ^(www\.)?redjohnsoncandy\.com$
RewriteRule (.*) http://www.yellowjohnsoncandy.com/index.php?option=com_content&view=category&layout=blog&id=3&Itemid=12 [R=301,L]
