For the record, I agree with Yaron that these are indeed illegally formatted
cookies according to NS's original specification.  I too think that the
current errata are incorrect, and possibly insulting, in saying that `MSIE
sends back the wrong cookie name and value'.

As far as I recall, we thought at the time that we had a working
compatibility hack which allowed use of the old header.  We now know we were
wrong.  We tried to save some bytes where we couldn't.

I think there is nothing technically wrong with the Set-Cookie-V1
alternative to the current compatibility scheme.  Bytes saved are not that
big an issue here: you don't often need to set a cookie.  I see lots of
servers which send a Set-Cookie header much more often than they really have

If server authors tell us that they prefer some form of Set-Cookie-V1 to the
current compatibility scheme, then I'd prefer to have Set-Cookie-V1, if it
can be had without horrible procedural side-effects.
