5 * Provides an API for getting and setting cookies that is
6 * syntactically and functionally similar to the server-side cookie
7 * API (`WebRequest#getCookie` and `WebResponse#setcookie`).

19 * Sets or deletes a cookie.
21 * While this is natural in JavaScript, contrary to `WebResponse#setcookie` in PHP, the
22 * default values for the `options` properties only apply if that property isn't set
23 * already in your options object (e.g. passing `{ secure: null }` or `{ secure: undefined }`
24 * overrides the default value for `options.secure`).
27 * @param {string|null} value Value of cookie. If `value` is `null` then this method will
28 * instead remove a cookie by name of `key`.
29 * @param {Object|Date} [options] Options object, or expiry date
30 * @param {Date|null} [options.expires=wgCookieExpiration] The expiry date of the cookie.
32 * Default cookie expiration is based on `wgCookieExpiration`. If `wgCookieExpiration` is
33 * 0, a session cookie is set (expires when the browser is closed). For non-zero values of
34 * `wgCookieExpiration`, the cookie expires `wgCookieExpiration` seconds from now.
36 * If options.expires is null, then a session cookie is set.
37 * @param {string} [options.prefix=wgCookiePrefix] The prefix of the key
38 * @param {string} [options.domain=wgCookieDomain] The domain attribute of the cookie
39 * @param {string} [options.path=wgCookiePath] The path attribute of the cookie
40 * @param {boolean} [options.secure=false] Whether or not to include the secure attribute.
41 * (Does **not** use the wgCookieSecure configuration variable)

99 * Gets the value of a cookie.
101 * @param {string} key
102 * @param {string} [prefix=wgCookiePrefix] The prefix of the key. If `prefix` is
103 * `undefined` or `null`, then `wgCookiePrefix` is used
104 * @param {Mixed} [defaultValue=null]
105 * @return {string} If the cookie exists, then the value of the
106 * cookie, otherwise `defaultValue`
