Check if top frame is right

[larsfres]

I have a website with frames and lots of people are opening the pages who are supposed to be in frames in fullscreen. So I need a little script that says, if the top frame is not <index.html>, then set top frame to <url>.
Almost like the little framebuster script, which checks if self==parent... or something.

Should be easy, but I have no idea. Anyone?

you would have to split the url :

if( parent.top.location.href.split("\/")[parent.top.location.href.split("\/").length])!="index.html")#
parent.top.loaction.href=newurl}

not tested but should not be far form the truth ...
