Many developers in search engine arena thinks that as meta's are not that important to use in search engines but thats not all the meta's can do. If you would like to refresh a page after certain interval of time you can do that in just a single line using Meta's and you dont need any server side language nor any load on the server for the same. Just introduce the following line in your Metas and your page will refresh every 60 seconds. <meta http-equiv="Refresh" content="60;url=http://www.go4expert.com"> This type of code can be useful for displaying user a message and redirect him after displaying the message. This does not need any overhead of server side and so is better than server side processing and delaying of timer to refresh the page.
