getting cookie expiration dates and paths

[yawnmoth]

To set a cookie, you're supposed to set document.cookie to something
like this:

cookie_name=cookie_value; expires=unixtime; path=/path/

Reading document.cookie back will tell you cookie_name and
cookie_value, but not the unixtime or the path variables that are
associated with a given cookie_name. Is there anything that can be
done to get this information?

Not that I know of, but why would your script need them?

To change their values? Based on the testing that I've done thus far,
it seems to me as though you need to provide the "correct" path to
update a cookie. If you try / when the cookie's actual path is /
whatever/, it doesn't seem to work. At least not with Firefox.

As for the expiration date... I don't really need that. I just
figured I'd ask about it while, at the same time, asking about the
path.
