Hey,

I'm using XmlHttpRequest to load an aspx file as below.

function GetPage(url)
{   
    var xmlhttp = false;
    
    try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); }
    catch(Ex1)
    {
        try { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); }
        catch(Ex2) { xmlhttp = false; }
    }
    
    if (!xmlhttp && typeof(XMLHttpRequest) != 'undefined')
    {
        try  { xmlhttp = new XMLHttpRequest(); }
        catch(Ex3) { xmlhttp = false; }
    }
    
    if (!xmlhttp && window.createRequest)
    {
        try { xmlhttp = new window.createRequest(); }
        catch(Ex4)  { xmlhttp = false; }
    }

    xmlhttp.open("GET", url, true);
    
    xmlhttp.onreadystatechange = function()
    {        
        if (xmlhttp.readystate == 4)
        {
            xmlhttpwindow = window.open('', 'newwindow', 'status=yes, toolbar=no, location=no, menubar=no, width=700, height=650, resizable=no, scrollbars=yes, top=150, left=200');
            xmlhttpwindow.document.write(xmlhttp.responseText);
        }
    }
    
    xmlhttp.send();
}

But I get an Javascript error, ASP.NET Ajax client-side framework failed to load.

Any ideas? I'm using .NET 3.5 Fx and VS.NET 2008.

Thanks in advance.
