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

Question

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:

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

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

Answer 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 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]

Answer 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.

Answer 3

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!

Answer 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
