''' Create a new cookie or replace an old one. If the `secret` parameter is
set, create a `Signed Cookie` (described below).
:param name: the name of the cookie.
:param value: the value of the cookie.
:param secret: a signature key required for signed cookies.
Additionally, this method accepts all RFC 2109 attributes that are
supported by :class:`cookie.Morsel`, including:
:param max_age: maximum age in seconds. (default: None)
:param expires: a datetime object or UNIX timestamp. (default: None)
:param domain: the domain that is allowed to read the cookie.
(default: current domain)
:param path: limits the cookie to a given path (default: current path)
:param secure: limit the cookie to HTTPS connections (default: off).
:param httponly: prevents client-side javascript to read this cookie
(default: off, requires Python 2.6 or newer).
If neither `expires` nor `max_age` is set (default), the cookie will
expire at the end of the browser session (as soon as the browser
window is closed).
Signed cookies may store any pickle-able object and are
cryptographically signed to prevent manipulation. Keep in mind that
cookies are limited to 4kb in most browsers.
Warning: Signed cookies are not encrypted (the client can still see
the content) and not copy-protected (the client can restore an old
cookie). The main intention is to make pickling and unpickling
save, not to store secret information at client side.
