session keeps expiring

[eluser]keevitaja[/eluser]
i'm having problem with ci session expiring. maybe after 5 minutes or so. anyone has an idea why it is doing that?

Code:

$config['sess_cookie_name']  = 'ci_session';
$config['sess_expiration']  = 0;
$config['sess_expire_on_close'] = FALSE;
$config['sess_encrypt_cookie'] = TRUE;
$config['sess_use_database'] = TRUE;
$config['sess_table_name']  = 'ci_sessions';
$config['sess_match_ip']  = TRUE;
$config['sess_match_useragent'] = FALSE;
$config['sess_time_to_update'] = 300;

Code:

$config['sess_match_ip']  = TRUE;

Is your ISP changing your IP address?

Raise this value up:

Code:

$config['sess_time_to_update'] = 600;  // 600 = 10 minutes - 300 = 5 minutes

Also make sure your session table is correct!

Code:

-- ------------------------------------------------------------------------

--
-- Table structure for CodeIgniter `ci_sessions`.
--
DROP TABLE IF EXISTS `ci_sessions`;

CREATE TABLE IF NOT EXISTS  `ci_sessions` (
  `session_id`    varchar(40)           DEFAULT '0' NOT NULL,
  `ip_address`    varchar(16)           DEFAULT '0' NOT NULL,
  `user_agent`    varchar(120)                      NOT NULL,
  `last_activity` int(10)      unsigned DEFAULT 0   NOT NULL,
  `user_data`     text,
  PRIMARY KEY (`session_id`),
  KEY `last_activity_idx` (`last_activity`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci ;

ip is not changing. i have same fenomenon on the local and public machine. mysql table is ok. and update time set to 600. still session expiring.

any thoughts?

@InsiteFX :

can it be due to session setting into php.ini like session.gc_maxlifetime value.
I 'm not sure if CI manages session setting by own.
please share you thoughts.

changing session.gc_maxlifetime doesn't help.

i'll try fresh ci installation...

Code:

phpinfo();

not sure if it helps. session keep expiring on zone.ee web hosting as well...

my site is http://lu.ee

[eluser]keevitaja[/eluser]
ok, session is alived according to

$config['sess_time_to_update'] = 3;

on CI fresh install. after specified time session_id is renewed. where did i go wrong or is it supposed to do that?

@Bhashkar

It is possible, but I have always seen it set to a default.

It almost sounds like he is getting a session_destroy someplace.

This is what my php.ini session stuff is set to:

Code:

session.gc_probability = 1
session.gc_divisor = 100
session.gc_maxlifetime = 1440
