What does status code 000 mean in the Nginx logs? I have the following  
in  
the config:

```
    location = /get-img.pl
    {
        limit_req zone=slow burst=10;
        proxy_pass http://service_perl;
    }

```

get-img.pl generates an image, writes it to disk and then returns  
“X-Accel-Redirect” to the image. Everything seems to be working just  
fine, I  
see delayed responses because of limit\_req in the logs (with code 200).  
Sometimes there are responses with code 503 for “greedy” clients that  
exceed  
the burst=10 parameter. All as expected.

However, occasionally I see a bunch of requests (around 5 to 20 within a  
few  
seconds of each other) with status code 000 and 0 for the body size in  
the  
logs. They are always from the same IP address for the entire bunch, so  
I’m  
guessing it’s requests that already went through internal  
“X-Accel-Redirect”  
redirect and then something happened. Connection aborted? Something  
else?  
Why not status code 503? That’s where you come in with a helpful  
explanation. 🙂
