What are cookies?
An Internet Cookie is a small snippet of information sent from a web server to a user’s browser, which then stores it.
A cookie is a piece of information in the form of a very small text file that is placed on an internet user's hard drive. It is generated by a web page server, which is basically the computer that operates a web site. The information the cookie contains is set by the server and it can be used by that server whenever the user visits the site. A cookie can be thought of as an internet user's identification card, which tell a web site when the user has returned.
Cookies are small files which are stored on a user's computer. They are designed to hold a modest amount of data specific to a particular client and website, and can be accessed either by the web server or the client computer. This allows the server to deliver a page tailored to a particular user, or the page itself can contain some script which is aware of the data in the cookie and so is able to carry information from one visit to the website (or related site) to the next.
On subsequent access to the same web server this server can then read back this information snippet and use it to “recognize” the user. These are an extension of the “Hypertext Transfer Protocol” (HTTP). This protocol makes surfing possible by allowing the requested web page to be delivered from the relevant server to your computer and then displayed in your browser.Back to Contents
