title: Add expires header to OpenShift Do It Yourself(DIY) cartidge
body: <p>I have launched Openshift DIY cartidge to server static web contents(html/css/js/images). I want to add expires headers for the contents so that contents are cached for local retrieval.</p>
  
  <p>I found <a href="https://forums.openshift.com/cache-static-files-served-by-openshifts-application" rel="nofollow noreferrer">https://forums.openshift.com/cache-static-files-served-by-openshifts-application</a>, but am not able to find .htaccess in DIY cartidge. </p>
  
  <p>Also <a href="https://stackoverflow.com/questions/13972629/add-expires-headers">Add Expires headers</a> was what I was looking for, but I can anyone help me find the file where these configurations should go in Openshift DIY cartidge?</p>
