Defined in:
lib/action_controller/cgi_ext/cookie_performance_fix.rb

Overview

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 groups.google.com/groups?th=e3a4e68ba042f842&seekm=c3sioe%241qvm%241%40news.cybercity.dk#link14

Constructor Details

#initialize(name = "", *value) ⇒ Cookie

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.
