hi everybody .
I have some question about re-login . In many web
that you have to log in before use, after you login and do
nothing in period time (about 1-2 hr or depend on setting) when you do anything agian .You have to re-login .
I would like to do that in my web but I don't know how to know
how long of client browser in status "do nothing" .
please suggest me to do that.
