XMLHttpRequest with "post" does not work (parameters are not passed to called routine); same code works in Chrome and IE.

Question

Here is my code:<br />
<br />
<pre><nowiki>function evalCtr(Ctr)
var xxxhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xxxhttp=new XMLHttpRequest();
else
{// code for IE6, IE5
xxxhttp=new ActiveXObject("Microsoft.XMLHTTP");
xxxhttp.onreadystatechange=function()
if (xxxhttp.readyState==4 && xxxhttp.status==200)
alert(xxxhttp.responseText);
var params = "oper=XXX&Center=YYY";
xxxhttp.open("post","c_ctr.cfm",true);
xxxhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xxxhttp.setRequestHeader("Content-length", params.length)
xxxhttp.setRequestHeader("Connection", "close");
xxxhttp.send(params);
}</nowiki></pre>
