This Wrox Blox provides a look into how to build and use custom ASP.NET httpHandlers to easily make advanced ASP.NET web sites. Learn fundamental concepts on what custom handlers are and how to use them. This Wrox Blox provides the opportunity to examine several real-world examples of custom httpHandlers to see how they can be applied and how they are developed. The author starts by covering built-in httpHandlers and adding an httpHandler to an ASP.NET Website.  Next, the author discusses registering httpHandlers, and then basic, synchronous and asynchronous handlers, and a simple HTML handler.  In addition, RSS, vCard, PDF, image resizer and recropper handlers are covered.
