Hello PAnkak,
forward Once you forward the request from say
Servlet A to any other Servlet/JSP control gets transferred from Servlet A to forwarded patrty & it never returns back to A for that request.
Include In include what you are doing is if Servlet A(Above example) is including the response of other Servlet/JSP(say B or B.jsp) so momentarily Control goes to B or B.jsp (they will genrate the response) control comes back to A & generated response is added in A's Response.
I hope this helps....feel free if you need more explanation.
