It may require some security settings? By default IE7 is more restrictive.

Are you working with XML? If so, is it being served as "text/xml"?

Please post the code so we can see what is going on with the problem.

re: XMLHttpRequest in IE7

my application when Country dropdown is selected the state and city drop down should be filled..

i am using this by callback.

my code is ..

if (window.XMLHttpRequest)
{
var xmlRequest = new XMLHttpRequest();
postData = __theFormPostData +
"__SCRIPTCALLBACKID=" + eventTarget +
"&_ScriptcallType=" + callType +
"&__SCRIPTCALLBACKPARAM=" + escape(eventArgument + "$" + callType).replace(re, "%2B");

if (pageUrl.indexOf("?") != -1)
{
xmlRequest.open("GET", pageUrl + "&" + postData, false);
}
else
{
xmlRequest.open("GET", pageUrl + "?" + postData, false);
}
xmlRequest.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlRequest.send(null);
try
{
response = xmlRequest.responseText;
status = xmlRequest.getResponseHeader("__SCRIPTCALLBACKSTAT US");

if (status == "200")
{
ShowResponse(response, context);
}
else
{
ShowErrorResponse(response, context);
}
else
{
var xmlRequest = new XMLHttpRequest();

xmlRequest.onreadystatechange = WebForm_OnClientCallbackComplete;

var __callbackObject = new Object();
__callbackObject.xmlRequest = xmlRequest;
__callbackObject.eventTarget = eventTarget;
__callbackObject.eventArgument = eventArgument;
__callbackObject.context = context;

addToCallbackList(__callbackObject);

postData = __theFormPostData +
"__SCRIPTCALLBACKID=" + eventTarget +
"&_ScriptcallType=" + callType +
"&__SCRIPTCALLBACKPARAM=" + escape(eventArgument + "$" + callType).replace(re, "%2B");

if (pageUrl.indexOf("?") != -1)
{
xmlRequest.open("GET", pageUrl + "&" + postData, false);
}
else
{
xmlRequest.open("GET", pageUrl + "?" + postData, false);
}
xmlRequest.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlRequest.send(null);
}

}

I would try also the classic method of creating the XMLHTTP object:
[HTML]var xmlRequest;
try
{ // Firefox, Opera 8.0+, Safari
xmlRequest=new XMLHttpRequest();
}
catch (e)
{ // Internet Explorer
try
{
xmlRequest=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
xmlRequest=new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e)
{
alert("Your browser does not support AJAX!");
return false;
}
}
}
[/HTML]

I may have the same problem. FF2 and IE6 both work, but IE7 does not. I looked at the network using wireshark. The XML request goes to the server, and the response comes back, but the response field is empty. I'm using prototype.js as the basis for the script.
