"and am very sure that a subscriber browsing through messages never touches that server except to get the logo if it's not cached"
That seems to be the case right now, but I can remember many times in the recent past when the page would "hang" because of a delay in loading the logo from adserv.stocksite.com.
Bob, If what you say is true about paid member not even going to the ad sites maybe you can try this little experiment: go to Ihub main page and clear all your cookies except the IHUB ones. go to the search box in upper right and type "zzz" and hit the search button. Check your cookie file and look at all the ad garbage their? Is your code placing it there or are the ad sites? adserv.stocksite.com app.quotemedia.com tribalfusion.com valueclick.com
I am sure I am just seeing things or maybe it is sdome Firefox quirk.....
