Losing sessions

[eluser]stef25[/eluser]
I have an app that I'm developing on localhost with a staging environment on a remote server. On my localhost I seem to always lose my sessions, after a matter of minutes. I get redirected back to my login page, which is the normal action for when I'm logged out. So far I have not found a particular action that seems to trigger it.

For some reason, with the same codebase, this does not happen on the remote environment. I just noticed that once the bug has "occurred" (ie I'm logged out), a new row is added in the sessions table. So it seems to be losing the connection between my computer and the session (?)

How can I start debugging this?

My session config for both environments is below

Code:

$config['sess_cookie_name']        = 'ci_session';
$config['sess_expiration']        = 7200;
$config['sess_encrypt_cookie']    = FALSE;
$config['sess_use_database']    = TRUE;
$config['sess_table_name']        = 'ci_sessions';
$config['sess_match_ip']        = FALSE;
$config['sess_match_useragent']    = FALSE;
$config['sess_time_to_update']     = 300;
$config['cookie_prefix'] = "";
$config['cookie_domain'] = "";
$config['cookie_path'] = "/";

Make sure the cookie domain and path are correct. Domain should be equal to the hostname in the base_url.

Are you using ajax calls? If so, they can cause the session_id to rotate (in your setup every 300 seconds), while the cookie hasn't been updated. You have to disable calls to sess_update() when processing an ajax request.
Search the forum, solutions have been posted for this problem.

Thanks for that, cookie domain was def wrong. What should the path be? User guide doesn't mention anything about this.

Normally, it's equal to the path in your base_url.
If your application is installed in the docroot '/' is ok.
