The jQuery ajax script below doesn't work on my site if url is without www. I checked Firebug and it doesn't send the ajax call.

$.ajax(
    {
        type: "POST",
        url: ".php",
        data: "page_type=index&sort=relevancerank&CartId=<?php echo $CartId;?>&HMAC=<?php echo $HMAC;?>",
        success: function(msg)
        {
            $('#content-holder').html(msg);

        },
        error: function()
        {
            alert("An error occurred while updating. Try again in a while");
        }
    });

I'm assuming the calling document URL is referenced as "mysite.", or "subdomain.mysite."? The XMLHttpRequest object (the engine that powers jQuery Ajax calls) can not perform "cross-domain" requests. A subdomain (e.g. 'www') qualifies. Make sure your requests are to the same subdomain.

You don't need to provide an absolute URL, you can simply provide a relative one, and it will work regardless if the your page is loaded with the www. subdomain or not:

//...
    type: "POST",
    url: "/beta/products.php",
//...

Is your server redirecting to the "www" domain possibly? This is probably just the same-origin policy preventing your outer page from accessing a different domain.

www. is just a naming convention - ajax will load on any address that can be looked up via dns, or it will work on an ip address as long as there is a server to respond to the request.

BUT - your page location and the ajax request need to be in the same domain for security reasons. To get round this restriction, you need to use something called JSONP
