How to find out session timeout duration?

Question

Is there a way to find out how long does a website timeout user's session? By looking into cookie? Or is it server side controlled?

Answer 1

the cookie contains a Expires field, read more about it here. a website could use either that .. or track the user with a persistent cookie and then decide itself what to do.

so, the answer to your question is: it depends on how the website's session management is implemented.
