POST is not working in IE11, GET works.

Question

Hi,
There is a problem while execution of POST function using XMLHttpRequest, the same code works fine in IE8,
here is the code.
if (window.XMLHttpRequest !== undefined)
{// code for IE7+, Firefox, Chrome, Opera, Safari
var httpOb=new XMLHttpRequest();
else
{// code for IE6, IE5
var httpOb=new ActiveXObject("Msxml2.XMLHTTP");
httpOb.open("POST",hostString,false);
httpOb.setRequestHeader("Content-Type","text/xml");
httpOb.send(xmlString);
var headers = httpOb.getAllResponseHeaders();
document.write(httpOb.responseText);
I can clearly see the httpOb gets assigned to XMLHttpRequest, while debugging in IE11,
The error message is "The System Cannot locate the resource specified", and this error comes on httpOb.send(xmlString);
assuming the url is wrong, how can it work in IE8 and gets data??
please help me, it's kind of urgent.
Thanks,
Sarva.

Answer 1

error message is "The System Cannot locate the resource specified", and this error comes on httpOb.send(xmlString);
FWIW I would run ProcMon to try to supplement what the message really means.  E.g. if it is written to a log file it will be associated with a WRiteFile event with an appropriate length specified.  Then you can go back from there to see what
other registry and file accesses may have been involved in its generation.
Good luck
