Exchange WebDAV 400 Bad Request: Why? - php

Question

I have been using WebDAV in PHP directly using XML. I have managed to create emails with attachments and so forth, but when i try to create a contact, I keep getting "400 Bad Request". Here is the webdav query and how i'm executing it:
<?xml version="1.0"?>
<g:propertyupdate
xmlns:g="DAV:"
xmlns:c="urn:schemas:contacts:"
xmlns:e="http://schemas.microsoft.com/exchange/"
xmlns:mapi="http://schemas.microsoft.com/mapi/"
xmlns:x="xml:"
xmlns:cal="urn:schemas:calendar:"
xmlns:mail="urn:schemas:httpmail:">
<g:set>
<g:prop>
<g:contentclass>urn:content-classes:person</g:contentclass>
<e:outlookmessageclass>IPM.Contact</e:outlookmessageclass>
<c:givenName>JoLynn</c:givenName>
<c:middlename>Julie</c:middlename>
</g:prop>
</g:set>
</g:propertyupdate>
And response:
HTTP/1.1 400 Bad Request
Connection: close
Date: Mon, 05 Jul 2010 08:41:43 GMT
Server: Microsoft-IIS/6.0
MicrosoftOfficeWebServer: 5.0_Pub
X-Powered-By: ASP.NET
Content-Type: text/html
Content-Length: 1709
MS-WebStorage: 6.5.7638
And sending the data: $h->fetch($url, 0, null, $exchange_username, $exchange_password, "PROPPATCH")
Any help greatly appreciated!¬
I started with Troy Wolf's example code at http://www.troywolf.com/articles/php/exchange_webdav_examples.php

Ah i fixed it, forgot to send some headers with the request (content-type, depth and translate headers to be precise!)
