Post your code.

function sendRequest(url){
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null)
{
alert ("Your browser does not support AJAX!");
return;
}
url=url+"&sid="+Math.random();
xmlHttp.onreadystatechange=stateChanged;
xmlHttp.open("POST",url,true);
xmlHttp.send(null);
}







function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
}
}

this error is only reported with the Mozilla browser, when it use IE, there is no error and AJAX functions are working properly...in mozilla browser also it is working if the server also running on the same computer..

what could be the reason for that...?

[acoder]

For POST requests you need to send the variables, not null. See link. See if that solves your problem.

OK....

thanks very much ...
