Apache 2.4 and php-fpm does not trigger apache http basic auth for php pages
apache,proxy,php-fpm,fcgi,centos7
After hours of research I understood that the reason that this occurs is because the ProxyPassMatch directive is the first directive to be processed, and this causes apache to ignore the other directives for the .php extensions.
