title: Append file date to css file in apache
body: <p>I am trying to find a way to make sure browsers dont cache versions of my css files everytime I push a new update.</p>
  
  <p>I was thinking the best way would be to somehow get the file timestamp of the css file on the filesytem and append append it tot he css URL somehow like www.mysite.com/css/style.css?13245645434</p>
  
  <p>Is this possible at all? If not, then any idea how i can make sure the browser gets a new version of the file when it is updated? I dont want to eliminate browser cache all together because if the file hasnt been touched then i would like it to be cached. However, when i push a new update i would like to someone tell the browser that.</p>
  
  <p>I understand i can write server side code to put the style.css?2342343 in but i want to see if its possible through apache at all.</p>
  
  <p>Thanks</p>
