Cookie Question

Hi, I am trying to get a cookie to set in Internet Explorer 7, I have tried several different setcookie() configurations, this is the latest. Yes, I read the manual and the user notes, but can't find anything specific about the different security levels in IE. $szCookieName = "MyCookie"; $nID = 2; $expireTime = 60*60; setcookie($szCookieName, $nID, time()-$expireTime,"/",www.mysite.com,false); However, they all work, only if I have the Privacy slider set to low in IE's options. As soon as I go up to medium, it will not work. And it works fine with firefox. The only difference I can see is that Medium Security adds the rule: Restricts first-party cookies that save information that can be used to contact you without your implicit consent. All I am storing is an integer value, why is IE seeing that as information that can contact you? Thanks for any help. Chris
