When you "expire" an existing cookie, you just overwrite it with some
data, including a new date that is in the past, effectively "expiring" it.

When you "change" that value of a cookie, you are also overwriting it with
some data, except this time you are not including an expired date.

They are both exactly the same thing, except for the date thing.  If you
were to "expire" the old one, then write a new one, it would require twice
as many steps, and accomplish nothing more useful.  Just overwrite it with
new data.

What were the other methods you found?
