Exercise 1 - Creating and Reading Cookies

When you access a website, a connection is made between your computer and the web server. The URL you typed is sent as a request to the web server. The web server, in turn, returns the website you requested, and then the connection between the server and your computer is closed. The server does not have memory to store information such as who you are or any settings/preferences that you would have specified on the web page.

Cookies are used to help the Web server remember you and your specified preferences. Cookies are small text files that store your information on your computer’s hard disk when you visit a website for the first time. At subsequent visits to the same website, the data stored in this file is used to personalize the website for you.

In this exercise, you will learn how to write and read cookies to personalize your website for the users. In the first task, you will download the Visual Studio Code workspace from the Intranet and open the ToDoList workspace.

In the second task, you will write JavaScript code to create and retrieve cookies.

In the third task, you will install the Internet Information Services (IIS) on your computer to host the ToDoList.html page and view the effect of cookies in your browser.
