./configure --with-http_random_index_module

    error_page  502 504 /error/type$arg_type/';

    location = /error/typeABC/ {
        root  /path/to/custom/;
        random_index  on;
    }

    location = /error/typeDEF/ {
        root  /path/to/custom/;
        random_index  on;
    }

    # fallback
    location /error/type {
        root  /path/to/custom/;
        random_index  on;
    }
