title: What is the difference between a concurrent connection and a concurrent request?
body: <p>I am trying to do some load testing and I was told that as parameters for testing, I should include both the number of concurrent requests and the number of concurrent connections. I really don't understand how there can be multiple requests on a given connection. When a client requests a webpage from a server, it first opens a connection, sends a request and gets a reponse and then closes a connection. What am I missing here?</p>
  
  <p><strong>UPDATE:</strong>
  I meant to ask how it was possible for a single connection to have multiple requests <em>concurrently</em> (meaning simultaneously.) Otherwise, what would be the point of measuring both concurrent requests and concurrent connections? Would counting both of them be helpful in knowing how many connections are idle at a time? I realize that a single connection can handle more than one request consecutively, sorry for the confusion.</p>
