I wanted to provide some examples this morning already, but
unfortunately, I can't come up with any right now. I /do/ know that
at one time I tested a lot of "real-life" cookies with Drakma, though,
and quite a few weren't RFC-compliant.

Allowing old-style Netscape cookies - at least optionally - would be a
good idea, yes.

The ideal solution, I think, would be a combination of the first two
strategies you mentioned. Follow RFC2109 by default, but provide one
or more sensible restarts in case a parsing error occurs.
Additionally, have some parameter (probably a global special variable)
which if set automatically invokes the "use old Netscape-style"
Does that sound reasonable?
