Besides, a lot of sites use a framebreaker code, and could bust out of the frames anyhow...
So if that happens, you suck them into your site, and they break out of your frames, and voila... your site is gone altogether... D'OH!
Here is a simple example of what I mean. Load it as one of the frames in a frameset, and you will see what I mean.
<HTML>
<HEAD>
<TITLE></TITLE>
<script>
<!--
function framebreaker()
{
if (top.location != location) {
top.location.href = document.location.href ;
}
}
-->
</script>
</HEAD>
<BODY onload="framebreaker()">
</BODY>
</HTML>
