Session Timeout/Expiry in java

Question

Is it advisable to set

<session-config>
        <session-timeout>-1</session-timeout>
    </session-config>

what are the dis advantages of doing so ??? Is there any better way to make sure the session never expires ???

Answer 1

There are no disadvantages. That just means the session won't expire. How would there be a "better" way?
