Constructor Details

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

Creates 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 (defaults to false). Secure cookies are only transmitted to HTTPS servers.

  • :http_only - Whether this cookie can be accessed by client side scripts (e.g. document.cookie) or only over HTTP. More details in msdn2.microsoft.com/en-us/library/system.web.httpcookie.httponly.aspx. Defaults to false.

These keywords correspond to attributes of the cookie object.

Raises:

  • (ArgumentError)
