Scott Mitchell returns to the ASP.NET Developer Center (has it really been seven days since his last article?) with a great article on URL Rewriting - creating an engine that will help you create simple, clean URLs, complete with PostBack.
Oh, and the article has the distinction of being the article that has given me the most conniptions. Not for the content, but for one section heading: 'Creating Truly "Hackable" URLs'. Fortunately, he meant URLs that can have sections hacked off of them.
