title: Android WebView XMLHttpRequest Keepalive
body: <p>when making XMLHttpRequests in an Android WebView, no keepalive connections are used as it seems. </p>
  
  <p>My desktop browsers all use keepalive when the requests are frequently made (eg. XMLHttpRequests triggered in a page's onload event are queued to the page's loading request connection). </p>
  
  <p>Does anybody know what the requirements for a keepalive connection are (timeouts, headers..) ? </p>
  
  <p>Thanks very much!</p>
