Syntax Diagram for <meta>
The "meta-information" of a document, contained within one or more
<meta> tags, is where application-specific information resides.

- Specifies the URL of the document to be automatically loaded if
"http-equiv=refresh" is specified. If a refresh is requested,
but no URL is given, the current document will be automatically reloaded

the second half of the content tag (see example below); it is
not a separate parameter.

If the user's browser understands "http-equiv=refresh", he will be
automatically shuttled to the new location. If not, the user has only to
click the hyperlink to go to the new location.
If you want to be sure a page is always current, you can have the page
auto-load itself (as this page does every 60 seconds):
