• What are HttpHandlers?
• What are HttpModules?

Answer Posted / anil

Http handlers are special applications that typically
handle files with certain extension. For example when you
request a file with extension .asp IIS routes it to ASP
processor. But what if I want to handle files with my own
extensions say .bipin? Http handlers allow us to do just
that. Now, you might be thinking what is the use of a new
file extension? Consider a case where you want to generate
graphics on the fly. In such cases you will write an Http
handler that will do your task. Note that Http handlers are
typically called for the specific file extensions they are
designed for. If you have worked with ISAPI extensions in
past you will find this concept very familiar.
