Does adding the followin tag in the header section of a html document prevent the loading of the document within a frame? If so, why does anybody bother with Javascript methods?
<META HTTP-EQUIV="Window-target" CONTENT="_top" />
It seems that browsers don't support <META HTTP-EQUIV="Window-target" CONTENT="_top" />
meta tag anymore, they simply ignore it. So that's why people bother with using JavaScript, as Gumbo suggested.
