Interact with program from site (like iTunes)

Th开发者_Python百科ere are iTunes links that will open up and app or an album in iTunes from a link in a web browser.

How does this work and can I do it in a C# .NET app?

iTunes registers the itms:// URI protocol in the registry and associates it with iTunes.exe.
The webpage then opens an itms:// link.

MSDN documents this, including a C# example.
