Utility class for setting/reading values from browser cookies. -Values can be written using the set method. -Values can be read using the get method. -A cookie can be invalidated on the client machine using the clear method.
-Removes a cookie with the provided name from the browser -if found by setting its expiration date to sometime in the past.
-The name of the cookie to remove
-(optional) The path for the cookie. This must be included if you included a path while setting the cookie.
-Retrieves cookies that are accessible by the current page. If a cookie
-does not exist, get() returns null. The following
-example retrieves the cookie called "valid" and stores the String value
-in the variable validStatus.
var validStatus = Ext.util.Cookies.get("valid");
-The name of the cookie to get
-Returns the cookie value for the specified name; -null if the cookie name does not exist.
-Create a cookie with the specified name and value. Additional settings -for the cookie may be optionally specified (for example: expiration, -access restriction, SSL).
-The name of the cookie to set.
-The value to set for the cookie.
-(Optional) Specify an expiration date the -cookie is to persist until. Note that the specified Date object will -be converted to Greenwich Mean Time (GMT).
-(Optional) Setting a path on the cookie restricts -access to pages that match that path. Defaults to all pages ('/').
-(Optional) Setting a domain restricts access to -pages on a given domain (typically used to allow cookie access across -subdomains). For example, "sencha.com" will create a cookie that can be -accessed from any subdomain of sencha.com, including www.sencha.com, -support.sencha.com, etc.
-(Optional) Specify true to indicate that the cookie -should only be accessible via SSL on a page using the HTTPS protocol. -Defaults to false. Note that this will only work if the page -calling this code uses the HTTPS protocol, otherwise the cookie will be -created with default options.
