在您的 VirtualHost 部分中定义此 RewriteMap 并重新启动 Apache:

Define this RewriteMap in your VirtualHost section and restart Apache:

RewriteMap lc int:tolower

然后在站点根目录 .htaccess 里面有这个代码:

Then inside site root .htaccess have this code:

RewriteEngine On

# external redirect from actual URL to pretty one
RewriteCond %{THE_REQUEST} (/product-category/subcategory)/?\?id=([^\s&]+) [NC]
RewriteRule ^ %1/${lc:%2}? [R=301,L,NE]

# internal forward from pretty URL to actual one
RewriteRule ^(product-category/subcategory)/(\w-]+)/?$ $1/?id=$2&fromDate=&parts= [L,QSA,NC]

${lc:%2} 会将 %2 中的值转换为小写.

${lc:%2} will convert value in %2 to lowercase.
