The following code might automatically bring up the new page five seconds after you load the current page.

<TITLE>Don't use this!</TITLE>
<META http-equiv="refresh" content="5;
http://www.acme.com/newpage">
</HEAD>
<BODY>
<P>If your browser supports Refresh,
you'll be transported to our
<A href="http://www.acme.com/newpage">new site</A>
in 5 seconds, otherwise, select the link manually.
</BODY>
However, authors should not redirect users with this markup since is non-standard, it disorients users, and it can disrupt a browser's history of visited pages. Instead, in order of preference, authors should:
- Configure the server to use the appropriate HTTP status code (301). Using HTTP headers is preferable because it reduces Internet traffic and download times, it may by applied to non-HTML documents, and it may be used by agents who requested only a HEAD request (e.g., link checkers). Also, status codes of the 30x type provide information such as "moved permanently" or "moved temporarily" that cannot be given with META refresh.
- Replace the page that would be redirected with a static page containing a normal link to the new page.
