我想使用mod_rewrite来检测用户代理是否是移动设备，如果是，则从www.example.com/foo.php重定向用户？a=1234到example.com/mobile/foo.php？a=12345。重定向必须保留查询字符串和请求的文件名。
我正在使用移动沸腾板(https://github.com/h5bp/mobileboilerplate.com)作为起点。在他们提供的.htaccess文件中，他们使用以下代码将所有移动浏览器重定向到移动网站，example.com/mobile/.

RewriteRule ^$ http://www.example.com/mobile [R,L]
代码运行良好，但不幸的是，无论请求的文件是什么，它都不会保留查询并重定向到页面。
我在之前的代码中添加了以下代码片段，但它在移动和桌面浏览器上都是内部错误。
// Previous Code Without ReWrite Rule
RewriteCond %{HTTP_HOST} ^example.com$
RewriteCond %{REQUEST_URI} !^/mobile/
RewriteRule ^(.*)$ /mobile/$1 [QSA, L]
我已经用尽了所有可以在网上找到的解决方案。我认为问题可能在于检查移动设备的条件，然后我添加了其他条件。任何帮助都将不胜感激，我仍将继续破解这个cookie。
我解决了这个问题，我正在回答自己的问题，以防其他人遇到类似的问题。
此外，感谢Kamil Srot为我指明了正确的道路，并建议我检查Apache Error.log。
这是我使用的导致错误的原始代码：

RewriteRule ^(.*)$ /mobile/$1 [QSA, L]
目标是将移动用户重定向到一个子目录并保留查询字符串。当我在.htaccess中使用此代码时，收到了内部服务器错误。问题是重写规则中的[QSA]标志。为了让整个程序正常工作，我不得不删除它。我还收到了一些提示，并被告知我也可以清理代码。
这是解决方案和最终结果，并对所发生的事情进行了逐行解释。
