You can disable caching for your website through .htaccess file. You can add following code to your .htaccess file:
<FilesMatch "\.(css|flv|gif|htm|html|ico|jpe|jpeg|jpg|js|png|pdf|swf|txt)$">
	<IfModule mod_expires.c>
		ExpiresActive Off
	</IfModule>
	<IfModule mod_headers.c>
		FileETag None
		Header unset ETag
		Header unset Pragma
		Header unset Cache-Control
		Header unset Last-Modified
		Header set Pragma "no-cache"
		Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
		Header set Expires "Mon, 10 Apr 1972 00:00:00 GMT"
	</IfModule>
</FilesMatch>
