<!--prevent the browser from accessing pages from the local cache. -
<meta http-equiv= "Pragram" content= "No-cache" >
<!--pages are not in the cache, and each visit refreshes the page. -
<meta http-equiv= "Cache-control" content= "No-cache, must-revalidate" >
<!--similar to the above meaning, you must reload the page--
<meta http-equiv= "Expires" content= "0" >
<!--the page expires in cache at 0 and must be re-subscribed from the server once the page expires
<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 "/>
