I have long been a proponent of using HttpHandlers when you need to serve up content which is not HTML or where you desire an alternative to Asp.Net WebForms.  As I am sure many of you know, the standard ASPX page is a pretty heavyweight solution that is really overkill and a performance drain for many scenarios.  As a result, I tend to create a lot of custom HttpHandlers in order to squeeze the most performance out of my applications.

A few years ago, Phil Haack created a great abstract class that I used as the foundation for my HttpHandler implementations.  Over time I found that there was additional functionality which should be abstracted out and thus I have created my own version of the abstract boilerplate.  Even within Phi’s original code I have changed some basic functionality to more closely follow the ASP.Net framework rather than creating a different paradigm.  In Phil’s original code, he passed the context through numerous method calls.  Not only did the original boilerplate pass the HttpContext, but often the methods were accessing properties on the Request or Response objects.   This is very different from most other ASP.Net development where Request, Response and Context objects are all first class properties on the base class.

I have also added additional methods which can be overloaded to handle permission checks and for setting the content MIME type and the content encoding type.  Finally, because AJAX requests often send any data in the body of the HTTP call, I have exposed this data in a Content property.
