Handle custom file extensions in ASP.NET Is there a way to make ASP.NET handle file extensions other than the ones configured by default that I'm overlooking in H-Sphere? Both ColdFusion and PHP appear to have the option to add additional extensions, but not ASP.NET? For example if I wanted to protect a .doc file on a server with .NET authentication, I'd normally add that extension and set a static file handler for it in the Web.config. In this case I want to rewrite an URL that ends with an extension other than .aspx. It looks like I can't use the .NET URL rewriting feature for that under H-Sphere though?
