title: How to manage session variables in a web cluster?
body: <p>Session variables are normally keept in the web server RAM memory.</p>
  
  <p>In a cluster, each request made by a client can be handled by a different cluster node. right?!</p>
  
  <p>So, in this case... </p>
  
  <ul>
  <li>What happens with session variables? Aren't they stored in the nodes RAM  memory? </li>
  <li>How the other nodes will handled my request correctly if it doesn't have my session variables, or at least all of it?</li>
  <li>This issue is treated by the web server (Apache, IIS) or by the language runtime (PHP, ASP.NET, Ruby, JSP)?</li>
  </ul>
  
  <p>EDIT: Is there some solution for <strong>Classic ASP</strong>?</p>
