I am building some URL logic that will go into an Http Module. The logic is somewhat expensive (includes a database lookup) and maps virtual URL's to the appropriate physical page.
I want to be sure that the logic isn't called if the request is for a physical page (the logic only applies to virtual URL's). How/where do I plug into the .aspx pipeline to ensure that my logic is only invoked if the request is not for a physical page?
