Hello!

Please correct me if I’m wrong, but I noticed if you open and  
immediately close a TCP connection to HTTP port without sending any HTTP  
headers or anything, it ends up as  
xxx.xxx.xxx.xxx - - [16/Dec/2010:18:14:34 +0900] “-” 400 0 “-” “-”  
in accesslog. Not that it’s a huge problem, but it confuses our log  
analyser/statistics a bit.

Is there a way to disabled those log messages in this case or am I  
missing something here?

Many thanks!  
Denis.
