我需要在单个页面上进行 301 重定向。如果我只是想让它在 www.example.com 上工作，我会：
redirect 301 /urisegment1/urisegment2/urisegment3 http://www.example.com/urisegment1/urisegment2/NEWURISEGMENT3
问题是，用户可以访问http://www.example.com/urisegment1/urisegment2/urisegment3 或有时https://www.example.com/urisegment1/urisegment2/urisegment3/如果他们已经登录并访问 SSL-受保护的页面。我还在本地设置了站点，因此我可以通过http://www.example.local/urisegment1/urisegment2/urisegment3访问它
我怎样才能让它适用于所有情况？
（这是问题的结尾，我当前的 .htaccess 文件在下面以防万一。请注意，这主要不是我自己的工作，它来自各种来源）。
