Delete All ABC cookies on your system. A Cookie is a small text file that a Web server can place on your hard disk. This file can be read by the server next time you visit the same site. Using this info the server can remember any preferences you may have chosen.
Cookies are quite safe.
They can't transmit computer viruses, they can't be used to inspect the contents of your hard disk and they can't be used to secretly extract information such as your email address. Also, a cookie can only be read by the server which originally wrote it, not by any other part of the Internet. Each time you click on a link to the Lab's home page, there is a check for the ABC Science cookie. If it is found, the Lab's sitemap page is served instead. The sitemap has exactly the same functionality as the Lab's standard home page, but is optimised for minimal graphics and loads at least 3 times faster.
