HTML Meta Http-Equiv Refresh
Specifies a delay in seconds before the browser automatically reloads the document. Optionally, specifies an alternative URL to load. E.g.
<META HTTP-EQUIV="Refresh" CONTENT="3;URL=http://www.some.org/some.html">
or (HTTP header)
Refresh: 3;URL=http://www.some.org/some.html
In Netscape Navigator, has the same effect as clicking “Reload”; i.e. issues an HTTP GET with Pragma: no-cache (and If-Modified-Since header if a cached copy exists).
Note: If a script is executed which reloads the current document, the action of the Refresh tag may be undefined. (e.g. <body onLoad= “document.location=’otherdoc.doc’>)
