Hi,i would want to write an iTunes-like application able to play the same music tracks available from the original iTunes.
But i need to know :

1) If iTunes , when searching for music , sends a request to a dynamic page , giving her some search parameters in the URL , and then if that page builds up dynamically the file list , which is an xml file , and sends it back to the requester in the HTTP response.
The xml file should be like any other podcast RSS feed , similar to this one http://www.odeo.com/tag/audioblog/rss.xml

2) The URL of such scripting page and what are its parameters.

I didn't find such infos at apple's web site,do you know something?

If not, do you think i can find them out using iTunes and some tool that monitors the HTTP queries outgoing from the applications? In that case,tell me what tools do it :D
