Q: what is HTTPHandler and HTTPModuler ?
http://www.15seconds.com/issue/020417.htm
ANS- During the processing of the HTTP Request only HTTPhandler will be called whereas more than one HTTPModuls can be called,
*HTTP handlers are the .NET components that implement the System.Web.IHttpHandler interface.
any class that implements the IHttpHandler interface can act as a target for the incoming HTTP requests.
HTTP handlers can be called directly by using their file name in the URL.

<httpHandlers>
 <add verb="supported http verbs" path="path" type="namespace.classname, assemblyname" />
<httpHandlers>
ASP.NET uses handlers for processing .aspx, .asmx, .soap and other ASP.NET files. 

handlers are mostly used for adding new functionalities to Web servers
