How to setup access log with different log level.

[nottherealbatman]

When setting up the access log you have to pass the write to it. Doing so it will take the loglevel of that writer which not always make sense. I want to be able to configure the access log to log non 200 responses as error and 200 as info. So that when I set the loglevel I only log what I need.

Is there a way to do so? The examples/documentation do not show this functionalty
