Apache "filesmatch" directive in htaccess not matching as expected

Question

I have a filesmatch directive in my .htaccess file:

<filesMatch "admin"> AuthUserFile /var/www/html/.htpasswd AuthType Basic AuthName "Protected Area" require valid-user </filesMatch> 

It matches http://www.website.com/admin (and sub-pages such as /admin/edit_page)

But not http://www.website.com/index.php/admin

(I also have a mod_rewrite rule to hide the index.php from most of the website, don't know if this conflicts).

The mod rewrite rule:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase / #Removes access to the system folder by users. #Additionally this will allow you to create a System.php controller, #previously this would not have been possible. #'system' can be replaced if you have renamed your system folder. RewriteCond %{REQUEST_URI} ^system.* RewriteRule ^(.*)$ /index.php?/$1 [L] #Checks to see if the user is attempting to access a valid file, #such as an image or css document, if this isn't true it sends the #request to index.php RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L] </IfModule> 

Answer 1

FilesMatch matches physical filesystem objects. index.php/admin is not one of those.
