    location /dbfile {
        rewrite  "^/dbfile/([0-9]{3})([0-9]{3})([0-9]{3})/(.*)$" 
                 /cache/$1/$2/$1$2$3__$4  last;
    }
 
    location /cache/ {
        flv;
        error_page  404  = @apache;
    }

    location @apache {
        proxy_pass  http://127.0.0.1:8080;
    }

However, Apache should pass flv headers by itself.
