regex - HTTP Basic Auth Exclude Single File

Question

Part of my .htaccess file looks like this-

AuthUserFile /path/to/.htpasswd
AuthName "Authorization Required"
AuthType Basic
require valid-user

Doing that requires the Basic HTTP authentication for the entire directory and the directories below it as well. However, I have a single file within that root directory, thubservice.php, that should not require the HTTP authentication.

From what I have seen, I need to use <FilesMatch />, but I cannot figure out the pattern to match all but that given file.

Answer 1

AuthUserFile /path/to/.htpasswd
AuthName "Authorization Required"
AuthType Basic
require valid-user
<Files "thubservice.php">
    Satisfy Any
    Allow from all
</Files>
