Cookies therefore help the web server customize pages based on your browsing habits. The cookie file only tells the server that a previous visitor has returned. It doesn't tell the web server who you are, your email address or anything else personal. Only you can provide additional information. You won't have to retype your name and address because the server can fill-in those fields for you.
Cookies do have restrictions.
The browser controls the cookie file and the information in each cookie. It is possible to have the web server do the work of requesting a cookie but most implementations use JavaScript to make the request local on your computer. All rights reserved.
