From: Nathan Sokalski on 7 Mar 2010 12:45 I probably made a bad choice of words there. What I meant was I want people to be able to add the *.dll to their web application and use the handler without needing to register it in their Web.config. The reason I created the handler is because it is used by one of the controls in my class library (it generates a *.gif image), so I need the handler to be available to the control at a known location (unless there is some alternative way for me to have the *.gif's generated and returned from a URL).
