Servlet Chain:
Servlet chain is a mechanism provided by java where a servlet can call another servlet.
Say i have request that is handled by multiple servlets. So the first servlet takes the request process it and send it the second servlet. The output of the previous servlet is input of the next/current servlet.
By this way the last servlet send the response to the user.

I wrote an article on servlet chaining
