title: What's the maximum count of active websocket connections supported by tomcat 7.0
body: <p>I'm developing a game server currently, to avoid developing the server from scratch, tomcat 7.0 is employed so that I can focus on the game logic.</p>
  
  <p>Base on the requirement, I use websocket to communicate with the clients, but when many clients have connected to the server, new connection can't be established, I doubt the count of established connections has reached the maximum count. By the way, APR connector is used by tomcat.</p>
  
  <p>So, my questions are:</p>
  
  <ol>
  <li>What's the maximum count of active websocket connections supported by tomcat 7.0.</li>
  <li>How to configure it.</li>
  <li>Is there any solution to load balancing of websocket, because apache and mod_jk can't be used for load balancing now.</li>
  </ol>
  
  <p>Any help will be appreciated, thanks in advance!</p>
