我想用大写字符http://localhost/A/B将URLredirect到使用.htaccess文件的小写版本http://localhost/a/b 。
使用正则expression式我可以捕获A和B，但有可能将它们转换为小写？
在.htaccess中
<IfModule mod_speling.c> CheckSpelling on </IfModule>
testing，工作，如果你有mod_speling启用。
或者，在服务器范围的httpd.conf中：
RewriteEngine On RewriteMap lc int:tolower RewriteCond %{REQUEST_URI} [AZ] RewriteRule (.*) ${lc:$1} [R=301,L]
