I've the next code to safeguard files with password in .htaccess:

<FilesMatch "\.(html|htm|css|js|php|swf|swz|xml|ico|jpg|jpeg|png|txt)$">
AuthName "Member Only"
AuthType Basic
AuthUserFile /path/to/password/.htpasswd
require valid-user
</FilesMatch>

How do i exclude came from here the should_be_excluded.php from being password protected? I'm able to alter the protection lines as needed, but I believe that something might be completed in the regex?

what about something similar to:

<FilesMatch "\.(html|htm|css|js|php|swf|swz|xml|ico|jpg|jpeg|png|txt)$">
    AuthName "Member Only"
    AuthType Basic
    AuthUserFile /path/to/password/.htpasswd
    require valid-user
</FilesMatch>
<Files /should_be_excluded.php>
    Order Allow,Deny
    Allow from all
</Files>

this will allow ALL accessibility excluded file?
