# Cookie is an immutable object which defines the data model of a HTTP Cookie.
# The data values within the cookie may be different from the
# values described in the literal cookie declaration.
# Specifically, the 'domain' and 'path' values may be set to defaults
# based on the requested resource that resulted in the cookie being set.
class Cookie
# [String] The name of the cookie.
attr_reader :name
# [String] The value of the cookie, without any attempts at decoding.
attr_reader :value
# [String] The domain scope of the cookie. Follows the RFC 2965
# 'effective host' rules. A 'dot' prefix indicates that it applies both
# to the non-dotted domain and child domains, while no prefix indicates
# that only exact matches of the domain are in scope.
attr_reader :domain
# [String] The path scope of the cookie. The cookie applies to URI paths
# that prefix match this value.
attr_reader :path
# [Boolean] The secure flag is set to indicate that the cookie should
# only be sent securely. Nearly all HTTP User Agent implementations assume
# this to mean that the cookie should only be sent over a
# SSL/TLS-protected connection
attr_reader :secure
# [Boolean] Popular browser extension to mark a cookie as invisible
# to code running within the browser, such as JavaScript
attr_reader :http_only
# [Fixnum] Version indicator, currently either
# * 0 for netscape cookies
# * 1 for RFC 2965 cookies
attr_reader :version
# [String] RFC 2965 field for indicating comment (or a location)
# describing the cookie to a usesr agent.
attr_reader :comment, :comment_url
# [Boolean] RFC 2965 field for indicating session lifetime for a cookie
attr_reader :discard
# [Array<FixNum>, nil] RFC 2965 port scope for the cookie. If not nil,
# indicates specific ports on the HTTP server which should receive this
# cookie if contacted.
attr_reader :ports
# [Time] Time when this cookie was first evaluated and created.
attr_reader :created_at
# Evaluate when this cookie will expire. Uses the original cookie fields
# for a max age or expires
#
# @return [Time, nil] Time of expiry, if this cookie has an expiry set
