title: HTTP Keep-Alive - If polling is maintained - Is there a maximum allowed for the connection?
body: <p>I have searched and found that the general consensus is that using the 1.1 keep-alive for an indefinate period of time is not proper use of the 1.1 keepalive type of connection. We are tunneling through a proxy and wish to maintain this socket for a long time (forever if possible).  </p>
  
  <p>Putting aside that it may be not proper, is there some generally accepted maximum length of time?</p>
  
  <p>The client side and server side software is custom so there is no issue there. We already have client with permanent persistent sockets. We are trying to overcome tunneling through a proxy which he have no access to using HTTP.</p>
  
  <p>Thanks</p>
