Nginx HTTP Server - Fourth Edition

Case 3

server { 
    server_name website.com; 
    location ^~ /doc { 
    [...] # requests beginning with "/doc" 
    } 
    location ~* ^/document$ { 
    [...] # requests exactly matching "/document" 
    } 
} 

This last case makes use of the ^~ modifier. Which block applies when a client visits http://website.com/document? The answer is the first block. The reason is that ^~ has priority over ~*. As a result, any request with a URI beginning with /doc will be affected to the first block, even if the request URI matches the regular expression defined in the second block.
