问题
Im trying to request the following entire site 301 redirect:
word.something.blah.domain.com --> http://www.word.com
I don't know how to write the 301 redirect rule.
Can someone help out?
回答1:
I will assume you are using the same directory to serve files on both domains. In which case, a Redirect clause won't work (infinite redirect loop).
With mod_rewrite, you can check the value of the current HTTP_HOST and take a decision based on that:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^([a-zA-Z0-9]+)\.something\.blah\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.%1.com/$1 [R=301,NE,L]
回答2:
put this into root directory of the subdomain:
Redirect permanent / http://www.word.com
回答3:
If you are keeping everything else the same - that is, the file names - but simply changing the domain, this code is all you need to put on the OLD DOMAIN htaccess:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.newdomain\.co.uk
RewriteRule (.*) http://www.newdomain.co.uk/$1 [R=301,L]
