Meta refresh breaks the Back button - http://www.w3.org/QA/Tips/reback
Sample code for Meta refresh redirect:
<html>
<head>
<title> Redirecting to correct page </title>
<META http-equiv="refresh" content="5;URL=http://jhpatel.blogspot.com/"> </head>
<body>
<center>
You will be redirected automatically in 5 seconds. Please bookmark the page at
<a href="http://jhpatel.blogspot.com/" > http://jhpatel.blogspot.com/</a>
</center>
</body>
</html>
Better way :
HTTP 301 Redirect - Permanent redirect (In JSP)
response.setStatus(301);
response.setHeader("Location", "http://www.jhpatel.blogspot.com/");
response.setHeader("Connection", "close");
