Hi Graham,

Up to 2.2.x, there was not much difference between server scope and 
request scope logging. I suspect that the original intention was just 
to omit the referrer which is appended in request scope.

I don't see any reason why request scope logging should not work for 
the quick handler. Probably all the per-directory log configuration 
will be ignored when using the quick handler, but IMHO that's just 
something that needs to be documented.

+1, because that would allow to use some of the new features, like  
correlating error log and access log entries via the log id.
