DOT NET – What is a cookie

Recently I got a message from one of the reader of my site that what exactly is a cookie. So I decided to wire a post dedicated to it .

  1. A cookie is name=value pair like variable which is stored as a file(persistant cookie) and which travels automatically between every request and response.
  2. Cookies are based on domains(website). As long as user is working with current web site cookie will be available.
  3. Cookies are maintained by browser but not by server which means cookies based websites are dependent on client.
  4. Cookies can be created as
    (i) In-memory cookie
    (ii) Persistant Cookie

An In-memory cookie means as long as user is working with app it will be available – also called as Session Cookie.

Persistant cookie means it will be stored in client physical location and available online as well as offline.
