I am using these rules and conditions in .htaccess to turn these
http://www.example.com/index.php/about/history
http://www.example.com/about/history/index.php
into
http://www.example.com/about/history
.htaccess
# ensure there is no /index.php in the address bar
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*index\.php\ HTTP/
RewriteRule ^(.*)index\.php$ $1 [R=301,L,NS]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /(.*)index\.php(.*)\ HTTP/ [NC]
RewriteRule ^index\.php/(.*) $1 [NS,NC,L,R=301]
Except there is a case where if the URL is
http://www.example.com/about/index.php/history/
It will result in an endless loop of redirecting. Now I know this is probably a rarity, but I'd like it not to happen if possible. How can I change my rules to accomodate this?
