Is it possible to make such a redirect?

Question

linux

Good afternoon. The webmaster made a new website (redesign) on WordPress. Did you enable some plugin or is it a permanent setting (not familiar with WordPress) - permalinks "/%category%/%postname%.html". Those. all pages of the site are now with html. However, the old site has pages both without html at the end and with it. Is it possible to do in .htacess that "if a link is in a certain section without html, then redirect to the same address, but with html". Or is it unrealistic?

Answer 1

possibly.

RewriteEngine On
RewriteCond %{REQUEST_URI} !^.*\.html$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ %{REQUEST_FILENAME}.html
