I love HttpHandlers. You can restrict access, in .NET 2.0, to specific files by using the System.Web.HttpNotFoundHandler (returns a 404 error) or the System.Web.HttpForbiddenHandler (returns a 403 error). James is showing some great suff on using HttpHandlers for security type stuff and some GDI code on the fly. Pretty interesting stuff. Don’t know that I’ll ever use the image stuff (never say never right?), but it shows how you can intercept the Http requests and manipulate the request/response stream.

James is now talking about the Caching features of ASP.NET which is pretty interesting.

Overall, a pretty good presentation. I’m looking forward to James being at edmug in June.
