Your server log is not in common log format or in NCSA extended/combined log format, so this is just a guess:
I'd say 231 is the total bytes sent, including the HTTP response header, and 0 is the total bytes sent excluding the header. So, nothing but the response header was returned.
The zero could also be the time in seconds required to send the response. I don't see any other common numerical entries that would make sense, but again these are just guesses. For a question like this, you should ask your host or server admin.
