by Chris Love

Published 23 June 2008

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.

Leveraging httpModules for Better ASP.NET Applications

by Chris Love

Published 5 May 2008

This Wrox Blox explains how to create different types of custom modules for ASP.NET web sites. Custom ASP.NET Modules are a great way to program advanced features to your web site. This Wrox blox discusses the difference between a custom httpModule and the Global.asax file. It also covers the steps in the ASP.NET pipeline. The examples include using a custom module to configure a site's initial settings, a background worker thread, and an IP blocker. Other examples show how to add content to the content being sent to the client, URL Rewriting, and a custom error handler.
