I have one folder inside WordPress root folder named links and there is a file called index.php inside this folder. at somewhere else in my WordPress site I do generate links such as http://mysite.com/links/index.php?link=55 (it's more than one link).
How can I have specific rewrite rule (like http://mysite.com/link/55) for above link inside my .htaccess file that don't interrupt own WordPress rule and don't throw Internal Server Error?
