# 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>:http_only</tt> - Whether this cookie is accessible via scripting or
|
|
# only HTTP. Defaults to +false+.
