I would like to know if it is possible to format a URL like https://site1.com/en/article-details.test-article?item=test to https://site1.com/en/article-details/test-article?item=test so basically changing the .test-article to /test-article.
Because of how my site works it only recognizes .test-article as a valid selector so reading up https://httpd.apache.org/docs/2.4/rewrite/flags.html it seems I may need to use a PT flag to show the user the desired URL but pass the correct one to my site.
So far I have this to replace the dot for a slash
RewriteCond %{REQUEST_URI} ^/([a-z]{2})/article-details.([a-z]{2})(/?)$
RewriteRule ^/([a-z]{2})/.* https://%{SERVER_NAME}/$1/$2 [L,NC,R=301]
Edit(this works to format the URL as per RavinderSingh13's suggestion)
RewriteEngine ON
RewriteCond %{REQUEST_URI} ^/([a-z]{2})/article-details.([^?]*)(/?)$
RewriteRule ^ https://%{SERVER_NAME}/%1/article-details/%2 [QSA,R=301,NE,L]
