Well what is your log format then? We can't possibly help you if we don't have the necessary info ;)

Do you want to block based on http referer? Or user agent string? Or something else entirely? The config snippet you posted indicates you are trying to block by referer. If you want to block a request based on the user agent string, you need to use the variable I noted ($http_user_agent).
