Ajax IE help

[eluser]Total Shop UK[/eluser]

Code:

$config['base_url'] = "http://www.totalshopuk.com/";

Code:

ajax('<?php echo base_url(); ?>_ajax/basket_add', 'status', poststr, 'POST');

Code:

function ajax(page, box, parameters, method, loadmessage, call, callparas);

Code:

var page = page.replace("http://www.totalshopuk.com", ""); // Page = /_ajax/basket_add

Code:

xmlhttp.open("POST", url, true);

http://totalshopuk.com - works
http://www.totalshopuk.com - doesn't work

Just cannot work it out :-S

Edit: exploding the base_url()and removing http://www.totalshopuk.com did the job.

Code:

$url_array = explode('/',base_url());
$x = count($url_array);
$url = '';
for ($i=3; $i<$x; $i++) {
    $url.= '/'.$url_array[$i];
}
return $url;
