# This is a cookie class that fixes the performance problems with the default one that ships with 1.8.1 and below.
# It replaces the inheritance on SimpleDelegator with DelegateClass(Array) following the suggestion from Matz on
# http://groups.google.com/groups?th=e3a4e68ba042f842&seekm=c3sioe%241qvm%241%40news.cybercity.dk#link14
class Cookie < DelegateClass(Array)
# Create a new CGI::Cookie object.
#
# The contents of the cookie can be specified as a +name+ and one
# or more +value+ arguments. Alternatively, the contents can
# be specified as a single hash argument. The possible keywords of
# this hash are as follows:
#
# name:: the name of the cookie. Required.
# value:: the cookie's value or list of values.
# path:: the path for which this cookie applies. Defaults to the
# base directory of the CGI script.
# domain:: the domain for which this cookie applies.
# expires:: the time at which this cookie expires, as a +Time+ object.
# secure:: whether this cookie is a secure cookie or not (default to
# false). Secure cookies are only transmitted to HTTPS
# servers.
#
# These keywords correspond to attributes of the cookie object.
