Was requested ages ago by Karl Jeacle, now that there is some better support for configuring the logging there's no excuse to add this. It helps with filtering from syslog.d / syslog.conf.

I think the condensed is better but it'll need to change post 2.0 to accomodate for logging the number of bytes read in the body of a titan request (and it's weird to hardcode a zero there.) 2.0 will ship with the legacy logging style thus.

will be used in the future to log how much byte a titan request uploaded.

add `log style <style>'; The old default is called `legacy' now, a new default format is added called `condensed', and `common' and `combined' to mimick Apache httpd and nginx (respectively) are also added.
