通过htaccess将旧域的子目录重定向到新域的根文件夹

Question

I have gone through several domain iterations on a wordpress blog and want to get old links redirected to the new domain. Initially the blog was in

olddomain.com/blog/

Now the blog is at the root level of

 newdomain.com

The old domain is set up as a domain alias of the new domain, it is not forwarded.

If anyone visits the site from

 olddomain.com/blog/

I need that to redirect to

 newdomain.com/

Thanks for your help.

Answer 1

1. Just create your .htaccess file and put it in the folder where you want to redirect from eg put it in the /blog folder.

2. Add the following lines to your .htaccess file.

   RewriteEngine On

   RewriteCond %{SERVER_PORT} 80

   RewriteCond %{REQUEST_URI} blog

   RewriteRule ^(.*)$ http://www.newside.com/newblog/ $1 [R,L]

Answer 2

If you are running an apache web server you can just do it vía a 301 redirect in a .htaccess file

1. Go to you olddomain.com FTP root
2. Create or edit .htaccess file

3. Add following lines

    RewriteEngine On RewriteRule ^blog/* http://www.newdomain.com/ [R=301,L] 

But this just redirect anything to the new domain, if you want to be "SEO friendly" (conserve canonical URLs) you will have to define a bit complex rule, take a look here: http://www.ksl-consulting.co.uk/301-redirect-examples.html

Answer 3

If you're not strictly limited to .htaccess and have the option to modify VirtualHost configuration for olddomain.com you can add this to the configuration block:

RewriteEngine on
RedirectMatch 301 ^/blog/(.*) http://newdomain.com/$1

This assumes newdomain.com is a separate VirtualHost and we're leveraging that for domain matching to prevent a redirect loop when the source is in a common folder.
