Questions about using session

[dgarrivier]

Hye all,

I want to use session for a website in order to store datas between pages.

It is easy to open the session and register the object variable.

However, I can not control if a user goes out my website (which should destroy the session) and then come back (which should start a new session)

So, if a user goes out and then back, the variables will still exist and I do not know how to detect this case ...

Can someone help me ?

In principle, no. HTTP is inherently stateless, so the server has no way of telling the difference between quietness and actual absence.

What you can do is look at $HTTP_REFERER when they hit a page on your site; if it's one of your pages then they haven't gone anywhere else in the meantime.
