<meta HTTP-EQUIV="Refresh" CONTENT="60">
Content = 60 means Refresh the page after every 60 second.

Search for tag as below:
Refresh scorecard
Syntax: Location.reload([forceGet])
The reload method forces a reload of the window's current document, i.e. the one contained in the Location.href property.
The reload method forces a reload of the window's current document, i.e. the one contained in the Location.href property.
It behaves in exactly the same way as the browser's reload button which, by default reloads from the cache.
If, however, the user has specified that the server be checked every time for an updated version, then the reload method will do the same.
You can force an unconditional HTTP GET of the document from the server by supplying 'true' for the parameter, but this should only be done if you believe that disk and memory caches are off or broken, or you believe the server has an updated version.
Variants: Location.reload - loads from cache
Location.reload(false) - loads from cache
Location.reload(true) - loads from server
Rediff score card uses
<meta HTTP-EQUIV="Refresh" CONTENT="480">for automatic refresh. For manual refresh they rely on JavaScript timer.
