    At one time, the iframe was IE-proprietary; however, the HTML 4.x
recommendation codified it as a standard [1] (albeit with fewer attributes
than recognized by IE). Netscape 4.x does *not* support the iframe element;
Netscape 6.x does.

    The site sniffs your browser and then redirects to a browser-appropriate
page. Try opening the link above in Netscape 4.x; you'll see that it is
redirected to frames.html. Look at the source in Netscape 4.x: it's nothing
more than a traditional frameset.

    Aside from lack of support from Netscape 4.x, concerns related to the
use of any type of framed document apply (e.g., bookmarking a page may not
maintain the document contained within the iframe; the address/location bar
will not reflect changes made to the source of the iframe, etc.).
