permanent links to article via htaccess

Hello,

I use on my domain wordpress with the apache rewrite rule module. At this time everything works correctly. Iw ould like to create subdirectories that point to an article or page like

https://mysub.domain.xxx => https://domain.xxx/<year>/<month>/<name&gt;

I set up my htaccess with
RewriteCond %{HTTP_HOST} subdomain.domain.xxx [NC] RewriteRule .* https://domain.xxx/<&#8230;..>

or a subdomain to mailman under domain/mailman/listinfo
but they don’t work. The rules follow always to the main WP document

Does anyone know a plugin?

Thanks
