Nginx Location Modifiers
= exact match
^~ preferential prefix match
~ and ~* regex match

Exact math Example

location = /favicon.ico {
	expires 1y;
}
http://www.site.com/favicon.ico


Preferential prefix

location ^~ /.well-known {
	try_files $uri = 404;
}
http://www.site.com/.well-known


Case insensitive regex

location ~* /uploads/.*\.php$ {
	deny all;
}
