我们最近完全重新设计了我们的网站并迁移到不同的 CMS 系统。我正在尝试基于旧的 Web 结构设置重定向，通过识别数百个可能的 URL 中的任何一个字符串来将所有内容定向到我们的新站点。出于本文的目的，我将重点关注字符串“_xdc.php”。
示例：我想http://www.mysite.com/_xdc.php?somerandomstring将 (301) 重写为http://www.mysite.com.
目前我正在使用这个：
RewriteRule ^.*xdc.*$ http://www.mysite.com [R=301,L]
只要它确实重定向到站点主页，此方法就可以工作。不过有两个问题。
第一个问题： ? 之后的胡言乱语 正在附加，我不希望它。基本上：
http://www.mysite.com/_xdc.php?somerandomstring变成http://www.mysite.com/?somerandomstring但我希望它是唯一的http://www.mysite.com第二个问题：如果我创建了一个包含字母“xdc”的新页面，它将被重定向。但是，当我尝试限制
^.*_xdc.php*重写时根本不起作用。我确定这与 _ 和 . 在“_xdc.php”中，但我不确定如何强制将这些特殊字符读取为纯文本而不是代码......
我错过了什么？我确信它很明显，但我仍然是 htaccess 的菜鸟，所以我非常感谢你的帮助！
如果需要，我在下面包含了我的完整 htaccess：
RewriteEngine On
## Begin - Rewrite rules to block out some common exploits.
# If you experience problems on your site block out the operations listed below
# This attempts to block the most common type of exploit `attempts` to Joomla!
