title: how to get the server to talk to the client
body: <p>I'm pretty new to web development, so excuse my ignorance. </p>
  
  <p>What I'd like to know is if there's a way to have the server broadcast a message to clients. An example of this would be a client page that has a newsfeed, and every time a new story comes in to the server, the server sends that information out to the client and the client updates its page's newsfeed. I don't want the client to constantly be polling the server every few seconds, asking "hey, is there a new story now? what about now? what about now???" I want the client to be doing its own thing, and then be interrupted by a message from the server. </p>
  
  <p>Is there a way to do this?</p>
