Cache control

• Webmasters also use meta tags to force browsers to show current pages, rather than viewing them from the cache.

• <meta http-equiv="Expires" content="0" />

• • • Causes browser to NEVER view the page in the cache

• <meta http-equiv="expires" content="Sat, 07 Jul 2007 07:07:07 GMT" />

• • • Causes browser to check for new content on 07/07/07, otherwise it'll show what's in the cache.
