title: Time out issues with chrome and flask
body: <p>I have a web application which acts as an interface to an offsite server which runs a very long task.  The user enters information and hits submit and then chrome waits for the response, and loads a new webpage when it receives it.  However depending on the network, input of the user, the task can take a pretty long time and occasionally chrome loads a "no data received page" before the data is returned (though the task is still running).</p>
  
  <p>Is there a way to put either a temporary page while my task is thinking or simply force chrome to continue waiting?  Thanks in advance</p>
