How to set session timeout?

[lsyhu]

Hey,

I am using WSAD to develope a web project. I put soem information in session to share in pages, such as user id. But the information in session lost after only several minutes. I think it's because session is time out. Does anyone know how to set the lenght of session, and how to check if session expires?

Thanks a lot.

Easy way of setting session length is by using the following

session.setMaxInactiveInterval(3600);

This is in seconds so the session will time out after being unused for 60 minutes in this example.

Any session variables you have set will equal null once your session expires.
