[Geoserver-users] Getmap with Http Post do not go

Hello,
To send a request XML to the server wms, I use xmlhttprequest, but in answer
I obtain strange carractères in the place of the image like this(in reponse
firebug):
File XML is the file of demonstration on geoserver and the test of this file
with TestWfsPost functions perfectly.
The response of Xmlhttprequest is a file text or xml. How can one recover an
image in the answer

here my code and after the special carractères

code html+javascript:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  <meta name="generator" content="PSPad editor, www.pspad.com">
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8 " />
  <title></title>
<script language="JavaScript">

var XML=state_wms();

function state_wms()
{
var XML;
XML = '<?xml version="1.0" encoding="UTF-8"?>'+"\n";
XML += '<ogc:GetMap'+"\n";
XML += ' xmlns:ogc="http://www.opengis.net/ows&quot;&#39;\+&quot;\\n&quot;;

XML += ' </Output>'+"\n";
XML += ' <Exceptions>application/vnd.ogc.se+inimage</Exceptions>'+"\n";
XML += ' </ogc:GetMap>'+"\n";
return XML;
}

// Send the request
function testPost()
{
var xmlhttp = new XMLHttpRequest();
xmlhttp.open ("POST", "http://127.0.0.1:8080/geoserver/wms&quot;,true\);
xmlhttp.setRequestHeader('Content-Type', 'application/vnd.ogc.wms_xml');
alert(XML);
xmlhttp.send(XML);
}

</script>

  <body>
<td><input type="button" onclick="testPost()" value="Testpost">
