Stay logged in, or not !

thanks for the answer and,yes of course I cant't really know that but before CI, it was something like that :
If I want to stay logged, cookie are created. on each page, if session dont't exist, check if cookie exist, if yes, session created, or not.

But here, session are mixed with cookies, so I'm little lost ! Currently session are highlander, so I can't test if session exist (first come to a page of the website), cause Ci_session will automatically load it and load eavery variable !
