I have an application in IIS where I set up a wildcard so that all file extensions are processed via the .net dll. I did this so that I can process some URL rewriting. I see at the top of the configuration screen where I can specify which extensions should be processed by what processors. What I am wondering is if there is a way to specify an extension that should not be processed by the wildcard. Specifically I know that .jpg, .gif, .css, .png and .js extensions should not go through it. Is there a way to tell IIS to just serve them normally?
