re post an HTTP Post to a different page

Hi

I have a service provider who's server intends to automatically posts
plain text (in csv format) to a receiver page on my server (which
accepts data and saves to a database). I have not yet set up this
page.

As a temporary measure I want to receive that text and automatically
forward it to a web page of a third party. (It will have the necessary
script to catch the text and save to a database).

Is there any simple script that I could use that could receive this
csv text and re-post unedited?

I do not want to use a re-direct.

Thanks ColinK
