title: Getting started with "long polling"
body: <p>I would like to start implementing to my site some "long polling like" techniques. </p>
  
  <p>Basically i need a main feature that refresh an HTML listing whether new data has been added to the DB.</p>
  
  <p>For my setup, I have a entry range VPS server with LAMP environement. 
  I know PHP, JS and i am familiar with Unix systems.</p>
  
  <p>What would be the right technology to achieve some long polling effects? </p>
  
  <p>Thanks a lot for any inputs</p>
