Strangely this is one of the easiest things to make, but then everything is easy when you know how!
How do I make an html redirect page - html URL redirect
Here's the code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<title>Your Page Title</title>
<meta http-equiv="REFRESH" content="0;url=http://www.the-domain-you-want-to-redirect-to.com"></HEAD>
Optional page text here.
<meta http-equiv="REFRESH" content="0;url=http://www.the-domain-you-want-to-redirect-to.com">
is the part that actually does the redirecting.
The number preceding the url (in this case zero) tells the browser the number of seconds to wait before redirecting to the new url.
You could set this to 5 and add some optional text to your page - something like:
"Please wait while we redirect you to our new site".
That's it! Just copy the code, save it (i.e. save as index.html) and your html redirect will work perfectly.
