What is web Session?
--------------------
- An abstract concept to represent a series of HTTP requests and responses
  between a specific web browser and server. HTTP doesn't support the
  notion of a session.
- A session's data is stored on the server (only 1 session per client)
- Sessions are often built on top of cookies.
- The only data the client stores is a cookie holding a unique session ID
- And on each page request, the client sends its session ID cookie, and the
 server uses  this to find and retrieve the client's session data
