Just reading on
Fritz Onion's blog about
some information he has on IIS7, I have to say this seems really cool. It's always bugged me that ASP.NET was incapable of doing such things as intercepting the response stream and that HttpModules were essentially humbled as a result. Sounds like in IIS7 we'll be able to do all sorts of cool stuff we can't do right now (for example a totally ASP.NET based file uploader
which just isn't possible right now...)
