301重定向到同名文件，同一个服务器，但域名不同

Question

I recently did an overhaul of a website in which we switched to a new master domain name for that website. The old domain is still active, and needed to be redirected to the new domain name.

The site still has the same root folder, and so there are a couple of files that were updated, but have the same name (ie index.php, about.php, contact.php).

I manually redirected all the files (via .htaccess) that no longer exist to new files with a manual redirect:

redirect 301 /old_file.php http://www.new_domain.org/new_file.php

However this will not work with the files that have the same name such as "index.php". I can still call the site by the old domain name. How do I properly refer these files so that I don't have a duplicate penalty from google?

I tried this and it did not work:

#Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.old_domain.org$[OR]
RewriteCond %{HTTP_HOST} ^old_domain.org$
RewriteRule ^(.*)$ http://www.new_domain.org/$1 [R=301,L]

Thank You

Answer 1

• Clear your browser cache and restart it
• Make sure mod_rewrite and .htaccess are enabled through httpd.conf and then put this code in your .htaccess under DOCUMENT_ROOT directory:

Code

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^(www\.)?old_domain\.org$ [NC]
RewriteRule ^ http://www.new_domain.org%{REQUEST_URI} [R=301,L]

Take a look at using the canonical tag as an alternative.
