Hello All: We are working on an application which stores successful userid in a session and used for subsequent user requests. On NT platform the app runs fine. However on UNIX platform, the values stored in session are not found (or the session not found?). Every time a request comes from user it appears to be looking for a new session. Checked application code and it works perfectly fine on NT. Seems something to do with Tomcat on UNIX platform. Appreciate if anyone can help... Thanks in Advance Bala Nemani
