Session management problem in response.sendRedirect

[kamal kumar sharma]

Hello,

I am facing an issue which i describe below.

Our application has request flow is like below.

Client -----> Apache HTTP 2.2.3(1) ---->JONAS 5.2.2
in this configuration the response.sendRedirect() is working well,there is no issue of session.

However as per new requirement we have to introduce a new Apache HTTP server in front of JOnAS server.

Client------> Apache HTTP 2.2.3(1) ---> Apache 2.2.3(2)---->JOnAS 5.2.2.

Now the problem starts,the response.sendRedirect() is no more working well. Apache 2.2.3(2) is unable to maintain the previous session.The request.getSession() is creating new sessionId rather than using the previous one.
How ever if we replace the sendRedirect with requestDispatcher.forward() it work's well.I am unable to understand the problem.

Regards,
kamal
