This tutorial will show how we can both write to and read from a simple cookie. VB version.

Using Cookies in web pages is very useful for temporarily storing small amounts of data, for the website to use. These Cookies are small text files that are stored on the user’s computer, which the web site can read for information; a web site can also write new cookies.

An example of using cookies efficiently would be for a web site to tell if a user has already logged in. The login information can be stored in a cookie on the user’s computer and read at any time by the web site to see if the user is currently logged in. This enables the web site to display information based upon the user’s current status – logged in or logged out.
