Break frames???

[Nator]

May be a very easy question, but how do I force a page to break out of frames everytime its loaded? I have a login page I want to to redirect to is the user is not logged in, but if the redirecting page is in a frame, it puts the login page in the frame. I've seen pages do this before, but I can't seem to find one (at least one here at work) that busts up frames.

if (top.frames.count != 0){
top.location = 'mysite.htm';
}

that should work
