Redirect top-level domain except for one page in Drupal


I have two top-level domains pointing to my Drupal installation, abc.com and xyz.com.

I'd like to force all pages to use abc.com, EXCEPT for one page (node), which should always use xyz.com.

I've tried a bunch of different .htaccess, none seem to work. This is the closest I've gotten:

# Redirect abc.com/path/to/my/page to xyz.com/path/to/my/page
RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com$ [NC]
RewriteRule ^path/to/my/page$ http://www.xyz.com$1 [R,L,NC]

# Redirect xyz.com to www.abc.com
RewriteCond %{HTTP_HOST} ^(www\.)?xyz\.com$ [NC]
RewriteRule ^ http://www.abc.com%{REQUEST_URI} [R,L]

The above works for the whole site redirect, but when you go to abc.com/path/to/my/page it redirects to the main page, abc.com. I also tried this:

# Redirect abc.com/path/to/my/page to xyz.com/path/to/my/page
RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com$ [NC]
RewriteRule ^path/to/my/page$ http://www.xyz.com/path/to/my/page [R,L,NC]

But that just gave me an error about too many redirects to xyz.com/path/to/my/page.

Any ideas? I'm not sure if my .htaccess code is wrong, or if it has to do with Drupal's clean URL functions, or what.

Here's the full Drupal .htaccess file:

Solution

  • Your code generates a loop. abc.com/path/to/my/page redirect to xyz.com/path/to/my/page, but all xyz urls are redirect to abc.com, so it would redirect back to abc.com/path/to/my/page, over and over again.

    # Redirect abc.com/path/to/my/page to xyz.com/path/to/my/page
    RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com$ [NC]
    RewriteRule ^(path/to/my/page)$ http://www.xyz.com/$1 [R=302,L,NC]
    
    # Redirect xyz.com to www.abc.com (except for /path/to/page)
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteCond %{REQUEST_URI} !^/path/to/my/page$ [NC]
    RewriteCond %{HTTP_HOST} ^(www\.)?xyz\.com$ [NC]
    RewriteRule ^ http://www.abc.com%{REQUEST_URI} [R=302,L]
    

    The rule in your first code was incorrect, redirecting abc.com/path/to/my/page to abc.com/ (and that didn't create a loop).

    RewriteRule ^path/to/my/page$ http://www.xyz.com$1 [R,L,NC]
    

    This was because $1 reference to the first pair of parentheses, but you didn't have any. Secondly you needed to add a / before it, or it would redirect to xyz.compath/to/my/page
