Waiting for XML data over HTTP   

I need to be able to write a program to sit in "listen" mode, and receive 
XML data over HTTP (POST method) from some remote program. Once the request 
is received, I need to process it and finally send back a response to the 
remote end that sent the request. How do I go about developing this using 
.NET? Most of the articles I've read on XMLHTTP involve first sending out a 
request and then processing a response. In my case, I want to be passively 
waiting for a request and then act upon it.

Related question: since this involves HTTP, and assuming I don't want to be 
usurping regular port 80 web server traffic on the same machine where my 
program is running, how do I configure my program to listen for the incoming 
XML requests packets over a separate port (say, 7200)?

Any help will be much appreciated. Thanks!

The easiest way is to run a web server and web service but listening on a 
different port, quite easy to set up in IIS for instance.
Are you able to use an existing web server like this or does the program 
have to do its own listening?

Re: Waiting for XML data over HTTP   

Actually - no: I won't be able to use an existing web server. I need to set 
up the program to do its own listening, so that it's totally independent and 
self-contained, with its own setup parameters.

Cassini is a small web server written in .NET:

I realize that cassini does more than you want to solve but I hope it 
shows how to listen on a certain port for HTTP connections.
