Looks like that.

The <META...> element is legal HTML 3.0, and the HTTP-EQUIV attribute
also.  Its purpose is to add HTTP headers, for example

<META HTTP-EQUIV=Expires CONTENT="Sat, 6 May 1995 12:00:00 GMT">

creates the following HTTP header:

Expires: Sat, 6 May 1995 12:00:00 GMT

However, AFAIK, there is no such thing as a `Refresh' header.

I am pretty sure that this is Netsc[r]ape-spectific.  I haven't found it
in the IETF HTTP drafts, and I have to agree with Ulf Kronman that such a
behaviour is evil, rude and nasty.

This means that Netscrape does not only add shitty extensions to their
browser, but also to their *server* which is much, much worse!

I fear this is the only solution.

It will collapse.  It will die horribly.  Netscrape is kiling off the
Net.  It is a plague that ought to be avoided.

The Web will live without Netscrape, or it won't live at all!
