Here is my first example using HTTP Module and HTTP Handlers with IIS7 in integrated mode. Note, you can debug your application in 'integrated mode', which is really cool! You'll need to follow this article to enable debugging. This is one of the powerful things in IIS7. You can also try out some URL-rewriting tricks. Here is an article from Scott Guthrie
