title: Is a Session ID generated on the Server-side or Client-side?
body: <p>This web page <a href="http://www.w3schools.com/ASP/prop_sessionid.asp" rel="noreferrer">http://www.w3schools.com/ASP/prop_sessionid.asp</a> states that a session ID is generated on the ServerSide.</p>
  
  <p>If this is the case, then how does a server know it's still the same client on the 2nd request response cycle? </p>
  
  <p>Surely the SessionId would be generated on the ClientSide so that the client would be sure of passing the same value to the server?</p>
