If I read the specs right:

New:  Cookie: $Version="1"; Customer="WILE_E_COYOTE"; $Path="/acme"

Easy enough to distinguish: look for $Version at the start of the

If I were to decode cookies, I would not even bother to distinguish

handle both formats.

I think that the spec would be messier, not cleaner, if a Cookie2
header were introduced.
