Nginx LUA

[nginxsantos]

Can anyone please help me with a lua configuration which I can embedded into
nginx.conf to send the following sepaately in access log.

user_agent_os
user_agent_browser
user_agent_version

At present all these fields are embedded in http_user_agent and I am writing
parser to parse at the receiver end. I am looking for some input where I can
send them separately as different fields from Nginx itself.
