HI Anoop,
>> Is it that the response of the first page becomes the request of the next
jsp....
No - "the next jsp" gets the same request, which is the whole idea of
"forwarding" a request. This is why you don't see the newly added headers (to
the response!).
I'm not sure what you are trying to do but you need to use
Response.containHeaders(java.lang.String name) to check if a header is already
there.
Hope this helps.
Regards,
Z.
