title: Is it possible to build a web-based chat client without a socket-based framework?
body: <p>I have heard that web-based chat clients tend to use networking frameworks such as the <strong>twisted framework</strong>. </p>
  
  <p>But would it be possible to build a web-based chat client without a networking framework - using <strong>only ajax</strong> connections? </p>
  
  <p>I would like to build a session-based one-to-one web chat client that uses sessions to indicate when a chat has ended. Would this be possible in Rails using only ajax and without a networking framework? </p>
  
  <p>What effect does it have to use a networking framework and what impact would it have on my app to not use one? Also any general recommendations for approaching this project would be appreciated.</p>
