Why does my session info get cleared when clearing history?

Question

I'm using CodeIgniter and I set my sessions like this example:

$this->session->set_userdata('psLoggedInUser', $UserN );

During development I want to clear chache (for example), and run 'clean'. But I want to preseve my logged-in sessions. For example, I also have gmail and linkedin on other tabs and I don't want to be logged out.

However, the moment I clear browser history making sure that log-in sessions aren't cleared, I find myself out of my development site. But I remain logged into gmail.

Why is this happening? Does it mean that gmail uses a different mechanism to keep track of logged in sessions?

For ex. When you want to clear browser cache from chrome with alt+ctrl+del there you can see multiple options, for cache its different option to select and for cookie its different
