nginx. Test which location used to process request

Question

I\'m wondering how do I know if a particular location[s] used to process request in nginx.

E.g.:

# 1
location / {}

# 2
location ~ /[\\w

If you just want to see which block was used, and don't care about returning otherwise valid results, it might be more straight-forward to use return rather than add_header.

location / {
    return 200 'location 1';
}

location ~ /(\w+\-)\.html {
    return 200 'location 2';    
}

location @named {
    return 200 'location named';
}
