301 Redirect for URL Changes
It is very important that when a search engine comes to index your site it is able to find the pages it’s looking for.
Many web sites lose out on valuable search engine traffic and suffer a loss of Google Page Rank when the site is redesigned or the page URLs are changed, due to incorrectly configuring redirects or omitting them altogether.
UPDATE: Here’s a 301 Redirect Cheat Sheet I came across that’s very handy.
The following excellent information is from WebConfs.com.
301 Redirect
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”.
You can Test your redirection with the Search Engine Friendly Redirect Checker.
Below are a couple of methods to implement URL Redirection
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-url.com” );
?>
ASP Redirect
<%@ Language=VBScript %>
<%
Response.Status=”301 Moved Permanently”;
Response.AddHeader(”Location”,”http://www.new-url.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-url.com”);
}
</script>
JSP (Java) Redirect
<%
response.setStatus(301);
response.setHeader( “Location”, “http://www.new-url.com/” );
response.setHeader( “Connection”, “close” );
%>
CGI PERL Redirect
$q = new CGI;
print $q->redirect(”http://www.new-url.com/”);
Ruby on Rails Redirect
def old_action
headers["Status"] = “301 Moved Permanently”
redirect_to “http://www.new-url.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.com/$1 [R=301,L]
Please REPLACE www.newdomain.com in the above code with your actual domain name.
In addition to the redirect I would suggest that you contact every backlinking site to modify their backlink to point to your new website.
Note* This .htaccess method of redirection works ONLY on Linux servers having the Apache Mod-Rewrite moduled enabled.
Redirect to www (htaccess redirect)
Create a .htaccess file with the below code, it will ensure that all requests coming in to domain.com will get redirected to www.domain.com
The .htaccess file needs to be placed in the root directory of your old website (i.e the same directory where your index file is placed)
Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301,nc]
Please REPLACE domain.com and www.newdomain.com with your actual domain name.
Note* This .htaccess method of redirection works ONLY on Linux servers having the Apache Mod-Rewrite moduled enabled.
How to Redirect HTML
Please refer to section titled ‘How to Redirect with htaccess’, if your site is hosted on a Linux Server and ‘IIS Redirect’, if your site is hosted on a Windows Server.

I am considering the google’s spider’s implementation. since google’s spider will fetch the redirected url (target url), the spider must have the ability to get the new domain’s IP address. So does Google’s spider will store the IP in some datastructure? so that when the fetch-list (a list of urls to be fetched )is generated, the IPs are filled.
Do you know that?
Very useful content. When programming with Java, we can use tuckey.org/urlrewrite/. It is a very powerful API for URL rewriting.
