Using existing session data from a non-CI website in a CodeIgniter website

Maybe I am wrong, and it probably makes no difference, but how about trying:

PHP Code:

ini_set('session.name', 'mysess'); 


before your call to session_set_cookie_params.

That's the way it's done in CodeIgniter's Session.php, instead of using the session_name() function.

Thank you but I think I have kind of hacked my way to make the names same on both of my websites. The real issue seems to be different session_id character length for the file names. Do you think it's difference in php version causing it or some CI setup??

This is what is happening now.

If I go to non-CI website and login the session cookie is still getting overwritten as soon as I visit any CI page.

But if I visit CI page first then login on non-CI website and then come back on CI page I can view the session data .... because plain php sees that a session has already been started (by CI) and just writes data into that file.
