HELP: No POST data found from a ASPX Script HTTPWebRequest into a PHP Page

[Limey]

We are working with a vendor who is trying to post some some XML data
to us. They are using an ASPX script to post to a PHP page of ours.
The problem is that in the PHP page, I cannot find any kind of POST,
GET or REQUEST data at all. Is there something that they or we are
doing wrong? Is there somewhere else that PHP/Apache hide the data?
The one thing I see in the PHP global variables that I don't
understand is the HTTP_EXPECT=100-continue. What does that mean and
is it affecting anything?

This is the script that they are using:

using System;
using System.Collecti ons;
using System.Componen tModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.Sess ionState;

base.OnInit(e);
}

this.btnSubmit. Click += new
System.EventHan dler(this.btnSu bmit_Click);

}

sUrlEncodeStrin g =

The $_POST, $_GET and $_REQUEST are blank arrays. This is $_SERVER
