Hi,
Small snippet from sun site :
"When a Servlet or JSP resource chooses to redirect the client (using a
response.sendRedirect(url)) the request object does not reach the second resource
directly since the underlying implementation is an HTTP redirect. The server sends an
HTTP
302 message back to the client telling it that the resource has moved to another URL,
and that
the client should access it there.
The bottom line is that the lifecycle of the initial request object that was accessed
in the
first JSP terminates with the end of the service method in the first JSP, or with the
reply from
the server. In a forward mechanism the request object is forwarded to the second
resource, thus
maintaining any object bindings to the request and its state, without a round trip to
the
client on the network."
HIH,
Rick

Sorry for the double post peeps.
When I asked:

I meant:
Are the 'req' and 'res' forwarded or does the target Servlet get fresh
params?

Although this will work just fine, it is less elegant than Robert's solution
of "RequestDispatcher.forward(request,response)".
I have always used "response.sendRedirect(URL)" when some sort of error
occurs within the currently executing Servlet.
Can anyone shed some more light on this topic? Do we even have access to
'req' and 'res' the objects with "sendRedirect(URL)" or are they out of
scope? Suppose I'll test it.

use response.sendRedirect(URL)
