Session Expiration Doubt - 1

[Sandeep Vaid]

P-273, Q-3 Option C)
"A session will become invalid after a timeout period defined by the servlet container"......MARKED AS TRUE

This statement means that if i have specified the timeout as 1 min, the session will ALWAYS expire after 1 min which is not true.
but i think this statement will be correct if we state it as :
"A session will become invalid after a timeout period defined by the servlet container if there is no activity by client
for this timeout period"..

In this context, a timeout period means inactivity. There's no need to mention it.

SRV.7.5 Session Timeouts
In the HTTP protocol, there is no explicit termination signal when a client is no longer active. This means that the only mechanism that can be used to indicate when a client is no longer active is a timeout period.
