我试图让这个 joomla 网站在移动设备上使用时重定向到一个名为 mobile.backuptoweb.co.uk 的子域。但我也想保留现有的重写规则，确保所有用户都被重定向到 www。url 和尾随 / 被删除。

目前它只是在移动设备上查看时重定向到无限循环。

将所有移动流量重定向到您的移动子域并在那里有第二个 .htaccess 文件进行移动测试和重写是否可行？

要检查我是否正确理解您的评论，

对于非移动访客

http://backuptoweb.co.uk/something重定向到http://www.backuptoweb.co.uk/something

对于移动访客

http://backuptoweb.co.uk/something重定向到http://www.mobile.backuptoweb.co.uk/something

除非它们来自您的移动网站。如果这是你想要的情况

http://backuptoweb.co.uk/something重定向到http://www.backuptoweb.co.uk/something

你怎么看这个逻辑和顺序？

  • 将 index.php 重写为 / （绝对不要使用 [L] 标志）

  • 检查移动访问者是否来自移动站点。如果是，请使用 [L] 重写并发送到http://www.backuptoweb.co.uk/something

  • 检查移动访问者（而不是来自移动站点。如果是，请使用 [L] 重写并发送到http://www.backuptoweb.co.uk/something

  • 用 [R=301,L] 将 no-www 改写为 www.backuptoweb.co.uk/something

一些标志可能需要工作。

看看这对你有什么作用。确保在测试时也清除浏览器缓存。

如果那里有任何 mod_rewrite 大师，我也欢迎提出改进建议
