The user agent detection might not always be reliable for some environments, so permit disabling it if the server administrator wants the check to happen in the browser rather than the server. The server administrator may also wish to disable the automatic refresh logic associated with the site header, footer and CSS. For example, these assets might never change anyway without doing a full server restart, so checking the modification time on each incoming request is not worth the system call.
