.htaccess exceptions

Hi I'm a .php coder trying to allow a Ruby on Rails website to access
some .php scripts. I notice everything get redirected with Ruby on Rails
in the .htaccess file.

How do I stop Rails from redirecting my .php scripts which would be in
another directory.

Cheers

(.htaccess is below)

# General Apache options
AddHandler fastcgi-script .fcgi
AddHandler cgi-script .cgi
Options +FollowSymLinks +ExecCGI

# If you don't want Rails to look in certain directories,
# use the following rewrite rules so that Apache won't rewrite certain
requests
