your question is vague and you didn't give any details, so i'm not going to spend much time answering.
http://www.submitcorner.com/Guide/Meta/refresh.shtml
gives instructions on the use of the Refresh Meta tag. The meta tag auto-refreshes the page based on a number of seconds.
if you want to do something other than auto-refresh, ask a more specific question.
