php - CakePHP sessions expiring with `Security.level` set to low and the `Session.timeout` set to 12000 -

my client complaining posts form , gets kicked login. have following code in app/config/core.php:

configure::write('session.timeout', '12000'); configure::write('security.level', 'low'); 

sessions should last 1,000 hours these settings, right? else going on?

i realize client might reporting bug me incorrectly , there may other factors involved, i'm not sure ask about.

the problem related internet explorer. that's far got; told client use better browser. problem solved.
