Didnt say thanks before, so thank you. One question I did not think of. Should the internal linking of the site be to the file name with extension or no extension?

I think it should be without extension but just want to double check.

Hi Ben. I tried this code on another hosting account and it did worked. The first account was a VPS account from Godaddy. The second was a shared account from the same hosting company. Im not sure why it works on one and not on the other. I did see the mod_rewrite option enabled.

Hi Ben. Thanks for your help but this does not work for some reason. Im testing it on an old site I have that is html and I just replaced php for html but both URL's still resolves.

I have been searching and testing for hours but cannot find a solution. I am able to get a URL to display with out the file exntension.

i.e domain.com/file instead of domain.com/file.php

The problem is both versions of the URL above work, therefore a duplicate content issue. How can I force the URL with the file extension not to resolve and give a 404 error? Or just redirect to the non extension URL?

IF it helps here is my code.

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+)$ $1.php [L,QSA]
