title: Different browser means a different client from the same machine
body: <ol>
  <li><p>If I open a new Tab (or Window) of the same browser I am working on (say Firefox), then it would be considered as the same client by the server.</p></li>
  <li><p>But, if I open the same URL from a different browser (say IE), then the server cannot identify this as the same client.</p></li>
  </ol>
  
  <p>So, how does the server identifies a client, internally?</p>
  
  <p>If I want a Server to uniquely identify a client even from a different browser (and not consider it as a new client), how do I do it from a Web Server (using Servlets)?</p>
