it is a nice hack but i have 2 problem with it and i cant read this 28 pages to see whether it was explaned or not
1: if you load your forum with WWW (
www.forumname.com) then
http://forumname.com is an external page ! and if you load your forum without WWW (
http://forumname.com) then
www.forumname.com is an external link
2: image that your footer of forum has a high-loading time script (for example a weak counter code ) there for you must stay to complet loading of it and whole page and then you will be redirected i think it is better there wont be any relevancy between perfermence of this hack and complete loading of the page
