Cookies are small files that the server sends to the requesting browser when a page is requested, which stores them. If the browser requests a page from this server again, it also transfers the cookies stored by this server to the server. This enables the server to determine that it is a browser that has visited this server before. In our store, cookies are used, among other things, to assign the shopping cart to a specific customer for the duration of the purchase and to enable the customer not to have to log in to the web store each time.
