How to add a cookie for a one time banner view

Need some expert help on this one.

[RobbieD]

How should the below code look if I want to enable a cookie so the ad only shows up once per browser session.

<SCRIPT language="JavaScript1.1" type="text/javascript">
<!--
var bust = Math.floor(1000000*Math.random()+1);
document.write('<A href="http://www.domain.com/a/blink.pl?region=23&bust=' + bust + '" target="_top">');
document.write('<IMG src="http://www.domain.com/a/bimg.pl?region=23&bust=' + bust + '&keyword=NULL" border="0" width="100" height="100" alt="Click Here!">');
document.write('</A>');
//-->
</SCRIPT>

Please provide the full code I would use for this to show once. Thank you for all your help.

Robbie,

Did you get my sticky?

It should have pointed you in the right direction to code this javascript without having to bump this thread all the time....
