Website log format?

Where can I customize website individual logs format? By default it doesn’t includes User-Agent and I would like to have it added to logs. General OLS logs located in /usr/local/lsws/logs have User-Agent, but the website logs located in /home/example.domain/logs doesn’t.

logFormat "%v %h %l %u %t "%r" %>s %b"
