Htaccess solution :

You might want to use mod_headers functions Cache-Control and Expires, for the file types you want the browser to not cache :

<filesMatch "\.(js|css|jpg|jpeg|png|gif)$">
FileETag None
<ifModule mod_headers.c>
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
</ifModule>
</filesMatch>

PHP solution :

You could also load each resource with a different timestamp each time your page is shown :

 <script type="text/javascript" src="myfile.js?time=<?php echo mktime(); ?>" />
 <link rel="stylesheet" media="screen" href="/myfile.css?time=<?php echo mktime(); ?>">
