8 * @class Ext.util.Cookies
9 * Utility class for managing and interacting with cookies.
14 * Create a cookie with the specified name and value. Additional settings
15 * for the cookie may be optionally specified (for example: expiration,
16 * access restriction, SSL).
17 * @param {String} name The name of the cookie to set.
18 * @param {Mixed} value The value to set for the cookie.
19 * @param {Object} expires (Optional) Specify an expiration date the
20 * cookie is to persist until. Note that the specified Date object will
21 * be converted to Greenwich Mean Time (GMT).
22 * @param {String} path (Optional) Setting a path on the cookie restricts
23 * access to pages that match that path. Defaults to all pages (<tt>'/'</tt>).
24 * @param {String} domain (Optional) Setting a domain restricts access to
25 * pages on a given domain (typically used to allow cookie access across
26 * subdomains). For example, "extjs.com" will create a cookie that can be
27 * accessed from any subdomain of extjs.com, including www.extjs.com,
28 * support.extjs.com, etc.
29 * @param {Boolean} secure (Optional) Specify true to indicate that the cookie
30 * should only be accessible via SSL on a page using the HTTPS protocol.
31 * Defaults to <tt>false</tt>. Note that this will only work if the page
32 * calling this code uses the HTTPS protocol, otherwise the cookie will be
33 * created with default options.

46 * Retrieves cookies that are accessible by the current page. If a cookie
47 * does not exist, <code>get()</code> returns <tt>null</tt>. The following
48 * example retrieves the cookie called "valid" and stores the String value
49 * in the variable <tt>validStatus</tt>.
51 * var validStatus = Ext.util.Cookies.get("valid");
53 * @param {String} name The name of the cookie to get
54 * @return {Mixed} Returns the cookie value for the specified name;
55 * null if the cookie name does not exist.
