title: Idle socket connection to Apache server timeout period
body: <p>I open a socket connection to Apache server however I don't send any requests waiting for a specific time to do it. How long can i expect Apache to keep this idle socket connection alive? </p>
  
  <p>Situation is that Apache server has limited resources and connections require to be allocated in advance before they all gone.</p>
  
  <p>After request is sent server advertise its timeout policy: </p>
  
  <blockquote>
    <p>KeepAlive: timeout=15,max=50</p>
  </blockquote>
  
  <p>If consequent request is sent in longer then 15 seconds it gets 'server closed connection' error. So it does enforce the policy. </p>
  
  <p>However, it seems that if no requests are sent after connection was opened Apache will not close it even for as long as 10 minutes.</p>
  
  <p>Can someone shed some light on behavior of Apache in such situation.</p>
