URL重写技术求助：移除URL中的/pagina/目录

目标：将 https://voorbeeld.nl/pagina/lid-worden.html 重写为 https://voorbeeld.nl/lid-worden，即移除URL里的/pagina/路径部分。

已尝试的Rewrite规则 #

RewriteEngine On

#Rewrite from /pagina/lid-worden.html to /lid-worden
RewriteRule ^pagina/(.*)\.html$ /$1 [R=301,L]

RewriteEngine On

#Rewrite from /pagina/lid-worden.html to /lid-worden
RewriteRule ^pagina/lid-worden\.html$ /lid-worden [R=301,L]

RewriteEngine On

#Rewrite from voorbeeld/pagina/lid-worden.html to /lid-worden
RewriteRule ^voorbeeld/pagina/lid-worden\.html$ /lid-worden [R=301,L]

问题现象 #

尝试上述规则后未成功，访问 https://www.voorbeeld.nl/lid-worden 时出现错误提示：
The requested URL was not found on this server.

服务器目录结构 #

• /assets
• /pagina（包含lid-worden.html文件）
• .htaccess
• index.html

本人对URL重写了解较基础，希望能得到协助完成目标，如有遗漏信息可随时补充。

重要说明：文中域名及文件夹名称“voorbeeld”仅为示例，非真实名称。
