$.get("/IndexAction.do",function(txt){
    alert(txt);
}

when i search in jquery-1.2.3,i found this

var xml = window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest(); 

then i modify it:

try {
    var xml = window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest();
}
catch(e) {
try
{
    xml=new ActiveXObject("MSXML2.XMLHTTP");
}
catch(e2)
{
try
{
    xml=new ActiveXObject("MSXML3.XMLHTTP");
}
catch(e3)
{
    alert("It's all error");
}
}	
}

Could you provide more details about your IE setup, specifically surrounding your security settings?

That might happen if the COM registration for Microsoft.XMLHTTP was damaged or missing in the system registry. Any reasonably updated copy of Windows (e.g., XP Service Pack 2 or greater) should work fine with what is there. Since the original reporter mentioned IE6, it's likely the system isn't very well updated.
