<div>I want to know is there any API in D7 is invoked when a page loads for first time or during page refresh/reload.</div>
<div>During anyother time that particular api should not be invoked.</div>
<div> </div>
<div>I have a custom form, and I keep certain variables in $_SESSION. During first time page loads I want to reset the session variables.</div>
<div>Also during page refresh (for windows IE F5) also I want to reset session variables.<br> </div></div></div> </div> </blockquote></div> </div></body></html>
