Drupalのインストールを指す2つのトップレベルドメイン、abc.comとxyz.comがあります。
1つのページ（ノード）を除いて、すべてのページでabc.comを使用するように強制したいのですが、常にxyz.comを使用する必要があります。
さまざまな.htaccessを試しましたが、どれも機能していないようです。これは私が得た最も近いものです：
# 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]
上記はサイト全体のリダイレクトで機能しますが、abc.com / path / to / my / pageにアクセスすると、メインページのabc.comにリダイレクトされます。私もこれを試しました：
# 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]
しかし、それはxyz.com/path/to/my/pageへのリダイレクトが多すぎるというエラーを私に与えました。
何か案は？.htaccessコードが間違っているのか、それともDrupalのクリーンURL関数に関係しているのか、それとも何なのかわかりません。
