title: Does purging cache on cloudflare also purge cache on browser?
body: <p>I have deployed my node app on heroku and I have cloudflare as CDN infront of it. Now my question is, if  there are changes to my javascript and if I purge the cache in cloudflare, will this automatically purge the browser cache? 
  I have following setting in my expressjs server file</p>
  
  <pre><code>if ('production' == process.env.NODE_ENV) {  //production
      var oneYear = 31557600000;
      app.use(express.static(__dirname + '/public', {maxAge: oneYear}));
  } else { //development
      app.use(express.static(__dirname + '/public'));
      app.use(express.errorHandler());
  }
  </code></pre>
  
  <p>If the purge on cloudflare doesnt purge browser cache, then what is the best strategy to purge browser cache every time I change my javascript or css files?</p>
  
  <p>Regards,
  Chidan</p>
