Logging by sidddy

[Psycojoker]

Hello,

As said there sidddy@e6b220d#commitcomment-22128490 the logging work by @sidddy looks very interesting. To avoid losing this work I'm creating this PR based on this commit (+ removing unrelated things) to avoid losing track of it.

I haven't tested it.

Got this error while playing with it.

The log file location is hard-coded to "/var/log/nginx/ssowat.log"... probably not a good idea for general usage ;-)

Make sure that:

1. The directory exists in your environment (or change the corresponding line of code to an alternative directory)
2. Directory and file are writable by your nginx user

Any news on this ?

I did a quick and dirty integration of the work but never tested it nor tried to make the things for it to work despite having received feedback, so no, nothing on my side :/

Trying to clean PR which are opened and inactive since more than 6 months ~ 1 year ... I propose to close this PR and keep it in the "Horizon" milestone in case somebody wants to take care of it later. But in the meantime there's no point in keeping all of these opened if there's no indication that someone might work on this soon.
