HTTP modules - subdirectories and private variables
I recently finished (for now--there's always more to do) one of the more complex HTTP modules I've worked on. I have an application first written in the ASP.NET 1.0 beta 2 time frame that's since been upgraded to 1.0, 1.1, and now 2.0. It had a lot of custom authentication and error handling code in global.asax, and for general architecture and server management purposes, I wanted to move this code into separate HTTP modules. I ran into a couple gotchas I wanted to document.
