    cache-control    
    Control how your pages are cached. The options you have are: public (default) - allows the page to be cached; private - the page may only be cached in private caches; no-cache - the page should never be cached; no-store - the page may be cached but not archived.    
    <meta http-equiv="cache-control" content="no-cache" />    
         
    expires    
    If the content of your page has an expiration date, you can specify this in your meta data. This is most often used by servers and browsers that cache content. If the content is expired, they will load the page from the server rather than the cache. To force this, you should set the value to "0", otherwise use the format YYYY-MM-DD@hh:mm:ss TMZ.    
    <meta http-equiv="expires" content="0" />
