title: How to prevent Browser cache for php site
body: <p>I have a php site running in cloud server.When ever i add new files css, js or images the browser is loading the same old js, css and image files stored in cache.</p>
  
  <p>My site has a doctype and meta tag as below</p>
  
  <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  
    &lt;meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"&gt;
    &lt;meta http-equiv="Page-Enter" content="blendTrans(Duration=1.0)"&gt;
    &lt;meta http-equiv="Page-Exit" content="blendTrans(Duration=1.0)"&gt;
    &lt;meta http-equiv="Site-Enter" content="blendTrans(Duration=1.0)"&gt;
    &lt;meta http-equiv="Site-Exit" content="blendTrans(Duration=1.0)"&gt;
  </code></pre>
  
  <p>Because of the above doctype and meta code am i loading the same files cached in browser instead of new one</p>
