Http Handler vs Http Module

• What is ASP .Net  HTTP Handler

An ASP.NET HTTP handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler. You can create your own HTTP handlers that render custom output to the browser

HTTP modules let you examine incoming and outgoing requests and take action based on the request.
