I can set the cookie on the homepage and look for it on the game-page. But then I must forbid bookmarking of the game-page. Easy play, I thought, just ask for the correct referer and redirect to the homepage in case the referer does not fit. Nope - this (damned) MS Explorer does not deliver a referer in a frameset, when the calling link is in a different frameset, so I have no chance to validate the referring link...Next try was splitting the cookie-stuff into two pages, basically like this:index.tpl: [showif [getcookie MyCookie]=] [redirect setcookie.tpl] [/showif] ... do other things if cookie exists ...setcookie.tpl: [setcookie ....] [redirect index.tpl]Of course, I have actually more code, to avoid endless loops. But the whole thing doesn't work either, because the redirect in setcookie.tpl prevents complete loading of the page and the cookie is NOT set.Now I am lost. Is it right, that the only way is to present a useless page before the game with something to click on?
