title: why the cookies continues working
body: <p>I have a question about the reason the web applications continues setting cookies, because the persistent HTTP conections use sockets, i.e.: websocket.</p>
  
  <p>HTTP 1.1 and 2 uses persistent http conections, with sockets in the client and server. These sockets are active a necessary time for loading a complete web page (HTML, CSS, images, etc), then the sockets are killed by the server. It is logic due to the server does not know what is doing the client. So, in this scenario, the use of the cookies is justified.</p>
  
  <p>But, with websocket i think the scenary is different, because it uses only one socket, so it means that after the conection is done, the server and the client uses the sockets for sending data.</p>
  
  <p>So, the question is... why are the cookies necessary if the server know who is the client?</p>
