use meta header to redirect a page to another one

<META HTTP-EQUIV="Refresh" CONTENT="10; URL=http://www.htmlhelp.com/">

tells the browser to load http://www.htmlhelp.com/ 10 seconds after the current document has finished loading. Not all browsers support this, so authors should provide an alternate means of moving to the new page where necessary. The Refresh header is sometimes used for "splash screens" or when a page has moved, but the technique is not very effective since users may not even be looking at the window that is to be refreshed. Some search engines penalize pages that use a Refresh of a few seconds or less.

remember that search engines don't like this kind of pages.
