>I want to know is there any API in D7 is invoked when a page loads for first time or during page refresh/reload.
>During anyother time that particular api should not be invoked.

>I have a custom form, and I keep certain variables in $_SESSION. During first time page loads I want to reset the session variables.
>Also during page refresh (for windows IE F5) also I want to reset session variables.
