I'm having a heck of a time setting allow / deny rules for certain directories and files + getting Nginx to keep handling other location rules.

For example, I want to only allow my IP address access to the WordPress login page:

location ~* wp-login.php {
allow 22.131.12.14;
deny all;
}

# Pass off php requests to Apache
location ~* \.php$ {
include /usr/local/etc/nginx/proxypass.conf;
proxy_pass http://127.0.0.1:80;
}

When I visit the WordPress login page, all I see is the raw PHP code.

How can I set up the first location block to allow me to add allow / deny rules, charset, headers, etc + have PHP files still processed by the second location block?
