Hi, Ben:
Thanks for your inputs.
1. How can I redirect post data to server2?
2. How can I store the entire original HttpServletRequest (on server 1) into a
distributed HttpSession? Aren't they still on server1? Or, Are you suggesting me to
use RMI?
3. What do you mean by make a container class for all data?
Sorry, I don't have much experience on Java Servlet. Some sample codes will help me a
lot.
Thanks,
Jackie

Subject: Re: Need some inputs
I can think of two solutions to your problem:
The easiest solution is to make a servlet (or CGI, etc) on server 1 which
gets the request, transforms the POST data to GET data, and performs a
redirect to server 2. The problem here is that sending large amounts of
data as a GET is probably not a good idea, and if your servlets on server 2
rely on cookies or other non-form data, you'll have a problem.
A more complete solution would be to store the entire original
HttpServletRequest (on server 1) into a distributed HttpSession. Then the
servlet on server 2 could use the request from the session instead of the
"true" request and would behave as if it received it directly. One thing
to note is that if the HttpServletRequest implementation is not
Serializable, you'll have to make a container class for all the data. I
have used this approach by making a SerializableHttpServletRequest class
and passing that to the session. It has worked so far for me.

other words, How can I make the following mechanism work? Client send
requests to server1, servlets on server1 will forward client's requests to
servlets on server2, and servlets on server2 send back the response to
client. I try servlet redirect and set servlet alias, but none of them
would solve the problem.
