What are cookies?

A cookie is information that a Web site puts on your hard disk so that it can remember something about you at a later time. (More technically, it is information for future use that is stored by the server on the client side of a client/server communication.) Typically, a cookie records your preferences when using a particular site. Using the Web's Hypertext Transfer Protocol (HTTP), each request for a Web page is independent of all other requests. For this reason, the Web page server has no memory of what pages it has sent to a user previously or anything about your previous visits. A cookie is a mechanism that allows the server to store its own information about a user on the user's own computer. You can view the cookies that have been stored on your hard disk. The location of the cookies depends on the browser: Internet Explorer stores each cookie as a separate file under a Windows subdirectory; Netscape stores all cookies in a single cookies.txt file; Opera stores them in a single cookies.dat file.

If you use technology that disabled cookies, you will not be able to take advantage of this feature, but the form will still function normally in all other ways.
