Paul -
Thank you for your response. After posting this question, I took a
look at RFC 2616 and found this:
10.3 Redirection 3xx
This class of status code indicates that further action needs to be taken
by the user agent in order to fulfill the request.
The action required MAY be carried out by the user agent without
interaction with the user if and only if the method
used in the second request is GET or HEAD.
My reading of that is that redirection with a POST can't be done.
Am I reading it wrong?

My situation is exactly this. I have provide an authentication
step for users accessing a resource the university pays for. The
university has a password and user name that should not be exposed to the
end user. I have an authentication facility that I pass a URL (to a
servlet) to be
connected to once the end user is authenticated. What I would like is to
be able to formulate a POST request in the servlet and then foward the
end user to it.
It sounds to me that you are suggesting that in the servlet I
should open an HTTP connection to the resource and read out the resulting
page as though it were the servlet's response. I'm going to try that,
though I can imagine various things going wrong.
Thanks again for the help;
