I can set the cookie on the homepage and look forit 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 thehomepage in case the referer does not fit. Nope - this (damned) MS Explorerdoes not deliver a referer in a frameset, when the calling link is in adifferent 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 wholething doesn't work either, because the redirect in setcookie.tpl preventscomplete 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 pagebefore the game with something to click on?Peter++++++++++++++++++++++++++++++++++++++++++++++++Peter Ostry - Vienna/Austria - www.ostry.comFon ++43-1-877 74 54 Fax ++43-1-877 74 54-21++++++++++++++++++++++++++++++++++++++++++++++++
