Msxml2.XMLHTTP formats my XML, why?

[gfa...@gmail.com]

Hello, I'm working on an ajax application in which I request things
from my php documents. The php responds in XML format. Now, the problem
is that when I receive that data using the ActiveX object
Msxml2.XMLHTTP, it formats my responseText, even though the
Content-type is text/plain.

The php file is here: http://rafb.net/paste/results/sIDyVF79.html
The javascript used to get the response:
http://rafb.net/paste/results/rkwyRD81.html

Now, in firefox I get the response as is sent by php. In IE, I get it
formatted as if were going to be "viewed". For example:

IE's responseText:

<?xml version="1.0" ?>
- <fxlresponse>
<error id="0" />
<login session="9fhih3jljhvcnk3v5ji8jdths3" id="1" name="gfaraj"
fullname="George Faraj" type="1" />
</fxlresponse>

FF's responseText:

<?xml version="1.0"?> <fxlresponse> <error id="0" /> <login
session="dnuv2gcr0tav8mub9mc5a3tlr7" id="1" name="gfaraj"
fullname="George Faraj" type="1" /> </fxlresponse>

Why does IE do this? I tried setting the Content-type to text/xml, and
use the responseXML.xml property, but FF didn't like that.

I was thinking of just returning responseXML to the handler, but since
the handler is a Java (GWT) function, I'm not sure how I should do
that.

Does anyone have any idea of how to fix this?
Thanks.

The links for the files have expired.. I'll post them here instead...
I'll appreciate ANY help on this.

The php file:

<?php

header('Content-type: text/plain; charset=utf-8');
//header('Content-type: text/xml');

require_once("config.php");

$request = Data::parse(Request::httpPost());

$response = '<?xml version="1.0"?>' . "\n" .
'<fxlresponse>' . "\n";

if (User::login($request->get("name"), $request->get("password")))
{
$response .= '<error ' . "\n" .
' id="0" /> ' . "\n" .
'<login ' . "\n" .
' session="' . Session::id() . '" ' . "\n" .
' id="' . User::id() . '" ' . "\n" .
' name="' . User::name() . '" ' . "\n" .
' fullname="' . User::fullName() . '" ' . "\n" .
' type="' . User::type() . '" />' . "\n";
}
else
{
$response .= '<error ' . "\n" .
'id="2" />' . "\n";
}

$response .= '</fxlresponse>';

// Send the response
echo $response;

?>

The javascript that does the posting:

var xmlHttp = false;
if (window.XMLHttpRequest)
{
// Mozilla, Safari,...
xmlHttp = new XMLHttpRequest();
if (xmlHttp.overrideMimeType) {
xmlHttp.overrideMimeType('text/xml');
}
}
else if (window.ActiveXObject)
{
// IE
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
if (xmlHttp.overrideMimeType) {
xmlHttp.overrideMimeType('text/xml');
}
}
catch (e) {
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}

if (!xmlHttp)
{
alert('Cannot create XMLHTTP instance');
return false;
}

try
{
xmlHttp.open("POST", host, true);
xmlHttp.setRequestHeader("Content-Type", "text/plain;
charset=utf-8");

xmlHttp.onreadystatechange = function() {
if (xmlHttp.readyState == 4)
{
delete xmlHttp.onreadystatechange;

if (xmlHttp.status == 200) {
var localHandler = handler;
var responseText = xmlHttp.responseText;
handler = null;
xmlHttp = null;
localHandler.@com.google.gwt.user.client.ResponseTextHandler::onCompletion(Ljava/lang/String;)(responseText);
} else {
handler = null;
xmlHttp = null;
alert("There was a problem retrieving the XML data:\n" +
xmlHttp.statusText);
}
}
};

xmlHttp.send(data);
return true;
}
catch (e) {
delete xmlHttp.onreadystatechange;
handler = null;
xmlHttp = null;
return false;
}
