This class is for objects that represent a "cookie jar" -- that is,
a database of all the HTTP cookies that a given LWP::UserAgent
object knows about.

Cookies are a general mechanism which server side connections can
use to both store and retrieve information on the client side of
the connection.
For more information about cookies refer to Cookie Spec and Cookie
Central.
This module also implements the new style cookies described in
RFC 2965. The two variants of cookies are supposed to be able to
coexist happily.

Instances of the class HTTP::Cookies are able to store a collection
of Set-Cookie2: and Set-Cookie: headers and are able to use this
information to initialize Cookie-headers in HTTP::Request objects.
The state of a HTTP::Cookies object can be saved in and restored
from files.
