http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

See Section 14.9

To prevent caching, for example, HTTP headers or HTML headers should contain

,----[ Code ]
| Pragma: no-cache
| Cache-Control: no-cache
`----

Also see: http://www.i18nguy.com/markup/metatags.html

Apache specifics at: comp.infosystems.www.servers.unix

To debug, use Firefox with the Live Headers extension.

Hope it helps,

Roy
