title: Symfony2 - stylesheet changes not reflected
body: <p>I am working on a web application and using Symfony2 for the first time.</p>
  
  <p>I have this problem: I have a template which references a stylesheet. Now, when I make changes to the stylesheet (e.g. change font colours), they are not reflected on the page when I open the page in my browser. It keeps on using the values of the original stylesheet as though it was never changed (in fact, I even removed the stylesheet completely, still the page displays the values of the original stylesheet).</p>
  
  <p>Here is the code in the template:</p>
  
  <p></p>
  
  <p>I have already tried clearing the cache and running Assetic:dump with no success. Any help will be greatly appreciated!</p>
  
  <p>p.s. I am working in the dev environment </p>
