monitoring http address

Hi,

Id like to know how to make the following:

The customer is sending an url http://...&MessageID=123 every minute.

I would like to listen to this server and get the MessageId from the url into a text file to put it later to a database.

Which technology should / can I use to achieve this?

Kind Regards
