What are cookies ?

Cookies are a feature of web browser software that allows web servers to recognize the computer used to access a web site. Cookies are small text files that are placed on your computer by websites that you visit. Cookies allow the web server to remember what information a user accesses on one web page to simplify subsequent interactions with that web site by the same user or to use the information to streamline the user’s transactions on related web pages. This makes it easier for a user to move from web page to web page and to maintain a virtual session. Cookies should make your online experience easier and more personalized.

When the volume of information is significant, the web site records on the client’s computer only an identifier (a unique number assigned to the user). Information is then stored locally on the server’s side, but is connected to the user through the identifier contained in the cookie.
