  <p>How do I configure Apache2 to allow multiple simultaneous connections from the same IP address?</p>
  
  <p>Here is my situation:</p>
  
  <ol>
  <li>a web app being hosted on a server.</li>
  <li>a remote client makes an request that may take 15 seconds to complete.</li>
  <li>the same remote client makes another (independent) request.</li>
  <li>at present, the 2nd request sits in a queue until the 1st request completes,
  since Apache2 seems to impose a limit of 1 connection per IP address.</li>
  </ol>
  
  <p>How do I override this default behaviour and allow the 2nd request to be processed in parallel?</p>
  
  <p>thanks in advance,
    David Jones</p>
