First of all difference between <jsp:fprward> and sendRedirect()..
(1) <jsp:forward> is executed at the server and. the intention is to peform a forward to some another resource with in the server/Context..
(2) But sendRedirect is treates an an separated request from the client
because it is executed at the cleisn machines!
i.e when ever you will use sendRedirect , the response will first send back to client for the present request and a separate request will be issued for the localtion specified in the sendRedirect(). since its a re request so you can specify any URL where you wanna request
Buz of this the scope of resources is more in case of sendRedirect!
I will suggest you to use sendRedirect to transfer the control to some another
servlet running in the other server.. as u can mention the complete URL with the needed parameters in the sendRedirect...
I hope This will solve any purpose~!
