使用.HTAccess从URL中删除？id = [关闭]

I have a page

root/pages/?id=webdesign

and I want to translate it into something like

root/pages/webdesign

To keep the prefix and replace the last part with a query string

RewriteCond %{QUERY_STRING} !^id=
RewriteRule ^root/pages/(.+)$ /root/pages/?id=$1 [L]

The RewriteCond is needed to prevent a rewrite loop.
