1 つのページで 301 リダイレクトを行う必要があります。www.example.com から動作させたい場合は、次のようにします。
redirect 301 /urisegment1/urisegment2/urisegment3 http://www.example.com/urisegment1/urisegment2/NEWURISEGMENT3
問題は、ユーザーがログインし てSSL-保護されたページ。また、サイトをローカルにセットアップしているので、http://www.example.local/urisegment1/urisegment2/urisegment3からアクセスできます
これをすべてのケースで機能させるにはどうすればよいですか？
（これで質問は終わりです。関連する場合に備えて、現在の.htaccessファイルを以下に示します。ほとんどが私の作品ではなく、さまざまなソースから引き出されていることに注意してください）。
