Cookies set by us
When you browse the web, each page is completely disconnected from the others: each page request is served by the server, which then forgets everything about the request. In some cases, such as when you have 10 pages of search results or when you are logged in, it’s helpful to carry information from page to page. So the server sets a session cookie that lets it remember, amongst other things, what is in your shopping basket or which page of search results you are on. This is called a ‘session’ cookie.
