Question

I have a primary domain – let’s call it xyz.com. I also have several other secondary domains such as abc.com def.com, ghi.com, etc.. These domain all have the same content.

I am trying to do a URL redirect in IIRF that will take any of the secondary domains, and replace it with my primary xyz domain.

This is the closest I have gotten.

RewriteCond  %{HTTP_HOST}  ^(?!(.*)\.xyz\.com)$
RedirectRule ^/(.*)$        http://*1.xyz.com/$1   

Problem #1: with this if I navigate to 123.abc.com, I am brought to .xyz.com (I am losing my sub-domain, I thought I could retrieve that with ‘*1’).

Problem #2: even when I go to http://www.xyz.com, I am redirected to .xyz.com this rule should obviously ignore any xyz.com domain

Answer 1

I took me a week, but I got it.

##### handles 3-part domains like "xxx.yyy.com"
    RewriteCond %{HTTP_HOST} ^(.*)\.(?!xyz).*\.com$        
    RedirectRule ^/(.*)$ http://*1.xyz.com/$1 [R=301]

and

##### handles 2-part domains like "yyy.com"      
    RewriteCond %{HTTP_HOST} ^(?!xyz).*\.com$        
    RedirectRule ^/(.*)$ http://xyz.com/$1 [R=301]
