Classes that Implement IHttpHandler

Class Description
HttpApplication Defines the methods, properties, and events common to all application objects within an ASP.NET application. This class is the base class for applications defined by the user in the global.asax file.
HttpRemotingHandler Implements an ASP.NET handler that forwards requests to the remoting HTTP channel.
Page Represents an .aspx file, also known as a Web Forms page, requested from a server that hosts an ASP.NET Web application.


You can write custom HTTP handlers to process specific, predefined types of HTTP requests in any Common Language Specification (CLS) compliant language. Executable code defined in the HttpHandler classes, rather than conventional ASP or ASP.NET Web pages, responds to these specific requests. HTTP handlers give you a means of interacting with the low-level request and response services of the IIS Web server and provide functionality much like ISAPI extensions but with a simpler programming model.

If your handler will access session state values, it must implement the IRequiresSessionState interface (a marker interface with no methods).
