Redirect multiple domains to one domain (with or without www before)

问题:

I have about 18 domains that need to be redirected to a new one. It has to work both with or without www prepended.

I've tried this:

     RewriteEngine on      Rewritecond %{HTTP_HOST} !^www\.domain\.com     RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L] 

That gives me a redirect loop (and only works with www before, i think?).

回答1:

RewriteEngine on RewriteCond %{HTTP_HOST} ^domain1.com [OR] RewriteCond %{HTTP_HOST} ^domain2.com [OR] RewriteCond %{HTTP_HOST} ^domain3.com [OR] RewriteCond %{HTTP_HOST} ^domain4.com [OR] RewriteCond %{HTTP_HOST} ^domain5.com RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=permanent,L] 

This will redirect all your 18 domains to your to your new single domain www.newdomain.com Otherwise you can use following code to redirect each domain if they are on separate hosting

RewriteCond %{HTTP_HOST} ^domain.com RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=permanent,L] 

回答2:

Instead of redirecting a.com, b.com, c.com to newdomain.com you can do this:

Redirect everything that is not newdomain.com to http://www.newdomain.com

RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} !newdomain.com$ [NC] RewriteRule ^(.*)$ http://www.newdomain.com/$1 [L,R=301] 

Credit for this goes to: http://www.raramuridesign.com/blog/83-dev-htaccess-redirect-a-domain-or-multiple-domains.html where it is explained in greater detail.

I tried it out for a client project and it works like a charm.

My experience after few days rummaging SO and other hosts instructions was disappointing. However, I cherry-picked the best workful parts of all of them and yields the following:

RewriteEngine On RewriteCond %{HTTP_HOST} ^www\.domain1\.com$ [OR] RewriteCond %{HTTP_HOST} ^domain1\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.domain2\.com$ [OR] RewriteCond %{HTTP_HOST} ^domain2\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.domain3\.com$ [OR] RewriteCond %{HTTP_HOST} ^domain3\.com$ RewriteRule ^/?$ "http\:\/\/www\.domain\.com\/" [R=301,L] 

• The above format is also according to cPanel style of redirection done in GUI.
• Redirection of www. version and non-www. version of domains is one of the issues which other solutions (at least I tried em!) couldn't solve it.
• Pay attention to ^/?$ in RewriteRule

If you want to redirect www version of the main domain to the non-www version of it, the last two lines should be like this:

RewriteCond %{HTTP_HOST} ^www\.domain\.com$ RewriteRule ^/?$ "http\:\/\/domain\.com\/" [R=301,L] 

Good Redirection!

回答4:

RewriteEngine on RewriteCond %{HTTP_HOST} ^domain.com RewriteRule ^(.*)$ http://www.newdomain.com/$1 [R=permanent,L] 

The ^domain.com solves the problem of the WWW, so all sub domains will now redirect.

Make sure that http://www.newdomain.com is not included in the RewriteCond.

That would cause a redirect loop
