title: c# How to get session from asp.net session cookie
body: <p>I'm pretty basic with .net</p>
  
  <p>But basically I've been told that to have session stickiness for my website in the environment it is to be deployed means I have to get session from the cookie <code>ASP.NET_SessionId</code>  </p>
  
  <p>But what does this mean/how do I use this?</p>
  
  <p>And where I am using my existing session code e.g. <code>Session.Add("Something", something)</code> do I now need to change this?</p>
