Okay, so you've set up a site and its domain name was www.reallybadhost.com. Tons of people come and visit your site. However, you being the genius that you are found a better host and now your new site is called www.reallygoodhost.com. How do you redirect visitors from your old site to the new one?
      These pages are called Century 21 pages. You've seen them everywhere: you stumble on a site that reads "We have moved!" Usually you are redirected automatically, as if by magic, to the new URL within seconds.
      The way you do this is by placing a simple META tag in the HEAD element.
< HEAD> < META HTTP-EQUIV="REFRESH" CONTENT="5; URL=http://www.newsite.com/">
</HEAD>
      Notice first that HTTP-EQUIV="REFRESH" This tells the browser that this META tag is going to refresh this page.
      Secondly, notice the CONTENT = "5; URL=http://www.newsite.com/" attribute. This means that in 5 seconds the page will redirect to www.newsite.com. Obviously, you could replace the number 5 with a different time period (i.e 10, 15, etc.) and also change the URL.
The Code
    Remember, that you should also include a physical link to the new URL on the page that the user can click on in case the browser doesn't redirect them.
