#1167: Requests for URLs that contain ".php" aren't routed to WPMU

 Using WPMU 2.8.6, I have just noticed a problem with WPMU's mod_rewrite
 rules.

 With WPMU installed at domain.com, I've noticed that a request for
 http://domain.com/file.php produces a standard 404 error (from apache),
 instead of a WordPress-powered 404 error page.

 If I try and load http://domain.com/filephp instead, the request is routed
 to WPMU (as expected).

 The contents of our .htaccess file is as follows:

 {{{
 RewriteEngine On
 RewriteBase /


 #uploaded files
 RewriteRule ^(.*/)?files/$ index.php [L]
 RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
 RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]

 # add a trailing slash to /wp-admin
 RewriteCond %{REQUEST_URI} ^.*/wp-admin$
 RewriteRule ^(.+)$ $1/ [R=301,L]

 RewriteCond %{REQUEST_FILENAME} -f [OR]
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule . - [L]
 RewriteRule  ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
 RewriteRule  ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
 RewriteRule . index.php [L]

 <IfModule mod_security.c>
 <Files async-upload.php>
 SecFilterEngine Off
 SecFilterScanPOST Off
 </Files>
 </IfModule>
 }}}

 It looks like the second-last RewriteRule might be causing the problem?


 A request for /anyfile.php on a standard WP site is routed correctly to
 WP, so it looks like an MU-specific problem.

 Standard WP uses rewrite rules like the following:

 {{{
 <IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteBase /
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule . /index.php [L]
 </IfModule>
 }}}

 So I'm not sure why WPMU has those other lines in there.
