ASP.NET.in.a.Nutshell.Second.Edition [Electronic resources] نسخه متنی

You can implement this interface to create a factory class that can
create IHttpHandler instances dynamically. ASP.NET
includes standard IHttpHandlerFactory classes like
PageHandlerFactory,
RestrictedResourceFactory, and
WebServiceHandlerFactory (which are not shown in
the class library documentation because they are private types).

Using the <httphandlers> section of the
web.config file, you can map specific requests
to directly to an IHttpHandler class or to an
IHttpHandlerFactory class, which will dynamically
create an appropriate IHttpHandler class by using
the GetHandler( ) method.

Note that the standard factory classes used by ASP.NET do not appear
in the MSDN help or this reference. These classes are marked
Private and are used exclusively by the ASP.NET
framework.

public interface 
IHttpHandlerFactory  {
// Public Instance Methods
public IHttpHandler 
GetHandler (HttpContext 
context , string 
requestType , string 
url , string 
pathTranslated );
public void 
ReleaseHandler (IHttpHandler 
handler );
}
