xml over http using multipart/form-data

[aman]

We have a requirement to do xml over http with our partner. Their
requirement is a bit unique (not traditional xml over http).
Here is an excerpt
"To upload a file the calling program must first create a programmatic HTTP
URL Connection with a “POST” request method. This connection should then
attach the file using a “multipart/form-data” “content-type” request
property, and then attach a Base 64 encoded user id and password using a
“Basic” “Authorization” request property. "

Created a HTTP Send Port and configured the authentication, URL, and
content-type property and fired off the request. Their application did not
receive the post as per to their requirements. After going through a lot of
red tape, finally was able to get my hands on what a sample post might look
like. Here it is:

POST /dev/Receive/... HTTP/1.1
Pragma: no-cache
Content-Length: 39798
Content-Type: multipart/form-data;
boundary=----------------------------b1be518f1a69
Accept: */*
Expect: 100-continue
Host: localhost
User-Agent: curl/7.12.2 (i386-pc-win32) libcurl/7.12.2 OpenSSL/0.9.7c
zlib/1.2.1

------------------------------b1be518f1a69
Content-Disposition: form-data; name="filename"; filename="catalogue.xml"
Content-Type: application/octet-stream

<?xml version="1.0" encoding="iso-8859-1"?>
<Catalog>
<data>blaah</data>
</Catalog>
------------------------------b1be518f1a69--

It looks like some type of mime encapsulation with all this boundary info.
I have not been able to replicate this type of a post from BizTalk using the
HTTP Send port and in combination with the MIME parser in the send pipeline.

Bottom line is: IS THERE a way to get this type of xml over http using
BizTalk 2004?.

Thank in advance for any help!

Kind regards,
aman

Your best bet may be a custom adapter. There is an example in the SDK of a
HTTP Adapter.

Someone may have already built one that they may like to share - he said
hopefully
It is on my to do list, along with a HTTP/HTML Form adapter

hmm, I had a feeling that this wasn't supported out of the box. The whole
idea of working with a package is to spend less time developing.
Any hopes for BTS 2004 SP1 to have this supported?

Greg, thanks a bunch for your input.
