Returns a jar that’ll automatically set the assigned cookies to have an expiration date 20 years from now. Example:
cookies.permanent[:prefers_open_id] = true # => Set-Cookie: prefers_open_id=true; path=/; expires=Sun, 16-Dec-2029 03:24:16 GMT
This jar is only meant for writing. You’ll read permanent cookies through the regular accessor.
