How to use 301 redirect for your web site?

301 redirect is the most efficient and Search Engine Friendly method for webpage redirection. It's not that hard to implement and it should preserve your search engine rankings for that particular page. If you have to change file names or move pages around, it's the safest option. The code "301" is interpreted as "moved permanently".

IIS Redirect

* In internet services manager, right click on the file or folder you wish to redirect
* Select the radio titled "a redirection to a URL".
* Enter the redirection page
* Check "The exact url entered above" and the "A permanent redirection for this resource"
* Click on 'Apply'

ColdFusion Redirect
<.cfheader statuscode="301" statustext="Moved permanently">
<.cfheader name="Location" value="http://www.new-url.com">

PHP Redirect
<?
Header( "HTTP/1.1 301 Moved Permanently" );
Header( "Location: http://www.new-domain-name.com" );
?>

ASP Redirect
<%@ Language=VBScript %>
<%
Response.Status="301 Moved Permanently";
Response.AddHeader("Location","http://www.new-domain-name.com/");
%>

ASP .NET Redirect
<script runat="server">
private void Page_Load(object sender, System.EventArgs e)
{
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location","http://www.new-domain-name.com");
}
</script>

JSP (Java) Redirect
<%
response.setStatus(301);
response.setHeader( "Location", "http://www.new-domain-name.com/" );
response.setHeader( "Connection", "close" );
%>

CGI PERL Redirect
$q = new CGI;
print $q->redirect("http://www.new-domain-name.com/");

Ruby on Rails Redirect
def old_action
headers["Status"] = "301 Moved Permanently"
redirect_to "http://www.new-domain-name.com/"
end

Redirect Old domain to New domain (htaccess redirect)

Create a .htaccess file with the below code, it will ensure that all your directories and pages of your old domain will get correctly redirected to your new domain.

The .htaccess file needs to be placed in the root directory of your old website (i.e the same directory where your index file is placed)

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) http://www.newdomain-name.com/$1 [R=301,L]

Please REPLACE www.newdomain-name.com in the above code with your actual domain name.
