Subject Re: mod_jk logging buffer
Date Mon, 15 Aug 2005 10:51:21 GMT

the problem is not only a delay but also an order of the messages. I
think all messages should be flushed to the file as soon as they come.

When I choosing to log 'info' messages I accept the fact that it will
slow down the processing of requests. That is always a drawback of
logging. The users should be aware of this.

I have never see apache server showing log entries in a wrong order or
delayed? Then why delay it in mod_jk??

By not flushing output immediatelly you are shirnking the functionality
of logging mechanism.
