title: How to Leverage Browser Caching using .htaccess ? (Google Maps api)
body: <p>So I have tested my page via Googles Page Insights 
  And it is currently telling me to: </p>
  
  <blockquote>
    <p>Leverage browser caching for the following cacheable resources:
    <a href="http://maps.google.com/maps/api/js?sensor=false&amp;language=en" rel="nofollow">http://maps.google.com/maps/api/js?sensor=false&amp;language=en</a> (30
    minutes)</p>
  </blockquote>
  
  <p>Its rather ironic as its a google resource from a google server But 
  Its always good to know how to do things I've tried to read about how to do this on a link google provided on the test page however it didn't really give an example of how to cache this external resource I've tried reading as much as I can and adding bits into my htaccess file but nothing seems to work.</p>
  
  <p>So I guess my question firstly is, is it even possible via the .htaccess file to cache this resouce?
  And if so how what code would I need to put in there to get it to cache the resource? </p>
  
  <p>Thanks you In advance for any help.</p>
