function makeRequest(url, async) {

if (window.XMLHttpRequest) {

} else if (window.ActiveXObject) {
// IE
try {
httpRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {

} catch (e) {
}
}
}
if (!httpRequest) {
return false;
}
httpRequest.open('POST', url, async);
httpRequest.send();
return httpRequest;
}
it is running excellent on localhost...but on google app engine it httpRequest.status equals 500 and goes in else statement.
WHY?
