URL Problem between Browsers

URL Problem between Browsers

Hi ppl,


I have the following code:
    
    var  folder_depth = './';
    var browserName = navigator.appName; 
    if (browserName == 'Microsoft Internet Explorer') {folder_depth = '../../';}
    var url = folder_depth + 'admin/useraccess/userslist.php'; 
    window.location = url;

I had to do a browser check because else the on IE9 the page would try to redirect to 

whilst on other browsers like Chrome it would redirect to 

Any idea on how I can avoid this check?

Thanks
Ivan
