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.

http_only

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

These keywords correspond to attributes of the cookie object.
