19 </span> * @class Ext.util.Cookies
21 Utility class for setting/reading values from browser cookies.
22 Values can be written using the {@link #set} method.
23 Values can be read using the {@link #get} method.
24 A cookie can be invalidated on the client machine using the {@link #clear} method.

33 </span> * Create a cookie with the specified name and value. Additional settings
34 * for the cookie may be optionally specified (for example: expiration,
35 * access restriction, SSL).
36 * @param {String} name The name of the cookie to set.
37 * @param {Object} value The value to set for the cookie.
38 * @param {Object} expires (Optional) Specify an expiration date the
39 * cookie is to persist until. Note that the specified Date object will
40 * be converted to Greenwich Mean Time (GMT).
41 * @param {String} path (Optional) Setting a path on the cookie restricts
42 * access to pages that match that path. Defaults to all pages (<tt>'/'</tt>).
43 * @param {String} domain (Optional) Setting a domain restricts access to
44 * pages on a given domain (typically used to allow cookie access across
45 * subdomains). For example, "sencha.com" will create a cookie that can be
46 * accessed from any subdomain of sencha.com, including www.sencha.com,
47 * support.sencha.com, etc.
48 * @param {Boolean} secure (Optional) Specify true to indicate that the cookie
49 * should only be accessible via SSL on a page using the HTTPS protocol.
50 * Defaults to <tt>false</tt>. Note that this will only work if the page
51 * calling this code uses the HTTPS protocol, otherwise the cookie will be
52 * created with default options.
