Upload xml using http post

I am posting this question again hoping someone will answer it.

Dear All

First of all, English is not my first language.

For one of our customers we are writing an application, that imports xml files.

We will get these files from an SAP application.

This application will send us these files using http POST.

Can anyone tell us how to configure http POST on the domino side. The xml files will be stored on the harddisk, not in the domino database.

Thanks in advance
