title: Prevent browser from caching input control value
body: <p>Most browsers will remember what you've typed into an input control so that you don't have to type it in again. Usually, this is useful</p>
  
  <p>I have a field in which the user needs to enter a unique reference for a newly created resource.  The reference us unique and a user should never type the same in twice (this would return an error).</p>
  
  <p>Is it possible to tell the browser <em>not</em> to cache the entries for this field only?  Auto-complete is causing user input errors in this case.</p>
