title: How to user predis for publish more than one time
body: <p>How can I publish info between the clients more than once?<br>
  I mean when I publish info from one user to other, he receives and backwards, but this is only once.<br>
  Because when one user send something to the other, the GET is being loaded and the receiving stops, how can I make it that way so the clients receives forever, not only once?</p>
