META refresh

META refresh is a type of META element in HTML which redirects the Web browser to another URL. It can take effect after a specified delay.

Example:

Redirecting you to wikipedia.org...

This code redirects the browser to http://www.wikipedia.org in 10 seconds. You can change the delay by altering the number before the URL. Note that there should be a semicolon between the number and the URL. You can have any title.

Its use is discouraged by the Web Content Accessibility Guidelines 1.0, [http://www.w3.org/TR/WAI-WEBCONTENT/#tech-no-periodic-refresh Guideline 7.4]
