When to write a handler or module .. any examples?

Question

I read about it, but still confused which use cases I will write with the http handler, not the http module (and vice versa). A few use cases for each will help.

Answer 1

HTTP Handlers and HTTP Modules Overview

Typical uses for custom HTTP handlers include the following:

• RSS feeds . To create an RSS feed for a website, you can create a handler that emits an XML format in RSS format. You can then associate a file name extension, such as .rss, with a custom handler. When users submit a request to your site that ends in .rss, ASP.NET calls the handler to process the request.

• Image server . If you want a web application to serve images of different sizes, you can write your own handler to resize the images, and then send them to the user as a response from the handler.

Typical applications for HTTP modules include the following:

• . , HTTP- , - XML . Internet Information Services (IIS) 7.0, , .
