This is an excellent article about using a combination of IHttpHandlerFactory and Attributes in an ASP.NET application to manage URL mappings. This technique is very powerful. It resembles work we've seen in CSK/GCN, .Text, OmniPortal, etc. but seems to take it to a more modular level. I am inclined to believe that this mechanism may have some overlap with ASP.NET 2.0's URL mapping feature. Anyway, thought I'd post this here: http://www.dotnetdevs.com/articles/AttributeBasedURLDispatch.aspx Here is a link to the introduction to HttpHandlers article by the same author: http://www.dotnetdevs.com/articles/IntroToHandlers.aspx
