title: Force refresh of cached CSS data
body: <p>Is it possible force the browser to fresh the cached CSS? </p>
  
  <p>This is not as simple as every request. We have a site that has had stable CSS for a while. </p>
  
  <p>Now we need to make some major updates to the CSS; however, browsers that have cached the CSS will not receive the new CSS for a couple of days causing rendering issues. </p>
  
  <p>Is there a way to force refresh of the CSS or are we better just opting for version specific CSS URLs?</p>
