∟Persistent Cookies Stored on Hard Disk

This section describes what are persistent cookies - cookies that are stored in files on hard disk. Persistent cookies will be sent back to the server when open the browser again later.

There are two kinds of cookies: persistent cookies and temporary cookies.

A persistent cookie is a cookie stored as a file on your computer, and it remains there when you close Internet Explorer. The cookie can be read by the Web site that created it when you visit that site again. You can use cookie.setMaxAge(s) to set the cookie to be persistent for 's' seconds.

A temporary or session cookie is stored only for your current browsing session, and is deleted from your computer when you close Internet Explorer. You can use cookie.setMaxAge(-1) to set the cookie to be temporary.

Other properties of a cookie object that you can set and get:

setPath(): Defines the path name so that when a pages under this path name is requested, the browser will send this cookie to the server. The path name is the URL without the server name and the port number parts.
setDomain(): Defines the domain name so that when a page under this domain name is requested, the browser will send this cookie to the server. The default domain name is the server name from which the cookie was created.
setMaxAge(): Defines how long the cookie should be stored on the browser's machine. MaxAge value is in unit of second. A negative value tells the browser to not save it to the hard disk. A zero value tells the browser to delete it.
setVersion(): Defines the version number to which this cookie is compliant with.
