Redirect HTML pages
Redirect web pages is common practice and often done with the meta tag refresh, but there are drawbacks and it is not recommended by the W3C. Using a HTTP redirection status code is preferred, but often simply not practical.
If you have a page http://oldsite.com/project/index.html and you need a redirect to http://mysite.com/project/, you simply place this index.html in http://oldsite.com/project/. In case JavaScript is disabled, the default meta refresh is used as a default:
index.html
<!DOCTYPE HTML>
<html>
<head>
<title></title>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<meta http-equiv="refresh" content="1; URL=http://mysite.com/project/" />
<script type="text/javascript">
window.location.href = "http://mysite.com/project/"
</script>
</head>
<body>
</body>
</html>
