title: connection establishment between client and server
body: <p>I want to know few basic things about <strong>connection establishment between client and server</strong>.
  suppose my web page has left menu where i have some links, on click of those  child pages 
  are open in the right side of master page .Now each link is requesting a new web page to 
  the server. Each web page is calling 5-6 web services asynchronously to get the data. So 
  if i am clicking on a left menu link, a connection is established between client and 
  server using <code>(client IP and Port)</code> to <code>(server Ip and port)</code>. But before the response comes, 
  suppose i clicked on other link of menu then how server knows that old conneciton is 
  terminated and new connection is established.next thing,when i clicked on a link, request 
  goes to server, server process the request but before sending the response if connection 
  is terminated from client side, what happens to that response, does server discards the 
  response and takes the new request for process. </p>
  
  <p>actually i have lot of confusion, so if anyone can explain me the full client-server round trip process,that will really very helpful . </p>
  
  <p>Thanks in advance</p>
