# Cookies are read and written through ActionController#cookies.
#
# The cookies being read are the ones received along with the request, the cookies
# being written will be sent out with the response. Reading a cookie does not get
# the cookie object itself back, just the value it holds.
#
# Examples for writing:
#
# # Sets a simple session cookie.
# cookies[:user_name] = "david"
#
# # Sets a cookie that expires in 1 hour.
# cookies[:login] = { :value => "XJ-122", :expires => 1.hour.from_now }
#
# Examples for reading:
#
# cookies[:user_name] # => "david"
# cookies.size # => 2
#
# Example for deleting:
#
# cookies.delete :user_name
#
# Please note that if you specify a :domain when setting a cookie, you must also specify the domain when deleting the cookie:
#
# cookies[:key] = {
# :value => 'a yummy cookie',
# :expires => 1.year.from_now,
# :domain => 'domain.com'
# }
#
# cookies.delete(:key, :domain => 'domain.com')
#
# The option symbols for setting cookies are:
#
# * <tt>:value</tt> - The cookie's value or list of values (as an array).
# * <tt>:path</tt> - The path for which this cookie applies. Defaults to the root
# of the application.
# * <tt>:domain</tt> - The domain for which this cookie applies.
# * <tt>:expires</tt> - The time at which this cookie expires, as a Time object.
# * <tt>:secure</tt> - Whether this cookie is a only transmitted to HTTPS servers.
# Default is +false+.
# * <tt>:httponly</tt> - Whether this cookie is accessible via scripting or
# only HTTP. Defaults to +false+.

# cookies.permanent[:prefers_open_id] = true

#
# This jar is only meant for writing. You'll read permanent cookies through the regular accessor.
#
# This jar allows chaining with the signed jar as well, so you can set permanent, signed cookies. Examples:
#
# cookies.permanent.signed[:remember_me] = current_user.id
# # => Set-Cookie: discount=BAhU--848956038e692d7046deab32b7131856ab20e14e; path=/; expires=Sun, 16-Dec-2029 03:24:16 GMT

# Returns a jar that'll automatically generate a signed representation of cookie value and verify it when reading from
# the cookie again. This is useful for creating cookies with values that the user is not supposed to change. If a signed
# cookie was tampered with by the user (or a 3rd party), an ActiveSupport::MessageVerifier::InvalidSignature exception will
# be raised.
#
# This jar requires that you set a suitable secret for the verification on ActionController::Base.cookie_verifier_secret.
#
# Example:
#
# cookies.signed[:discount] = 45
# # => Set-Cookie: discount=BAhpMg==--2c1c6906c90a3bc4fd54a51ffb41dffa4bf6b5f7; path=/
#
# cookies.signed[:discount] # => 45
