libhttp-cookies-perl 6.01-1 (amd64 binary) in ubuntu zesty

 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
 <URL:http://curl.haxx.se/rfc/cookie_spec.html> and
 <URL:http://www.cookiecentral.com/>. HTTP::Cookies 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.
