If My Website Frontend Customers once login (Not Backend Admin Users), they should not be logged out Automatically. If they manually logout Then only it should be logged out.
I want this because if any registered customer comes to my site and view any product or add to cart then I can send them emails.
Please suggest if it is Possible.
This is my Current setting
In Magento Admin
magento version : 1.9.2.0

Go to System -> Configuration -> Web -> Session Cookie management and set it to the value you need in the correct store view or if you have only one, in the default config.
Also keep in mind this has to be the same or lower than session.gc_maxlifetime in your PHP config. 0 should give you an endless session.
