CI session expires rapidly

In your config file look at this line:

Code:

$config['sess_time_to_update']     = 300;

300 seconds (5 minutes) is the default. See the user guide at
http://ellislab.com/codeigniter/user-gui...sions.html.

A session, as far as CodeIgniter is concerned, is simply an array containing the following information:

The user's unique Session ID (this is a statistically random string with very strong entropy, hashed with MD5 for portability, and regenerated (by default) every five minutes)

The rest of the session data is maintained, but the sessionID is, by design, regenerated every five minutes. I think that is why you are seeing your sessionID changing "more or less every 4 minutes" ;-)
