HI...I'm new in Ajax....i'm trying to retrieve a multiple rss and display it in my browser...it's working fine in IE.....but the request seems cannot be processed in Mozilla....

this is the code that i've written :

PHP Code:
 function makeRequest(urldiv) {
   
        var 
http_request false;
        
        if (
window.XMLHttpRequest) { // Mozilla, Safari, ...
            
http_request = new XMLHttpRequest();
            
            if (
http_request.overrideMimeType) {
                
http_request.overrideMimeType('text/xml');
                
// See note below about this line
            
}
        } else if (
window.ActiveXObject) { // IE
            
try {
                
http_request = new ActiveXObject("Msxml2.XMLHTTP");
            } catch (
e) {
                try {
                    
http_request = new ActiveXObject("Microsoft.XMLHTTP");
                } catch (
e) {}
            }
        }

        if (!
http_request) {
            
alert('Giving up :( Cannot create an XMLHTTP instance');
            return 
false;
        }
        
http_request.onreadystatechange = function() { showContents(http_requestdiv); };
        
http_request.open('GET'urltrue);
        
http_request.send(null);
    } 
How can i solve dis problem.?
