Potentially useful to quickly know which mirror we're talking to.

We had a GeoIP mirror in the past based on nginx and its GeoIP module,
but it didn't perform very well, due to the high latency (asking a
central server for the package and then redirected to the closest
mirror).

One of the reasons for offering this service, is so we can relieve
mirror.pkgbuild.com which is burning a ton of traffic (50TB/month),
likely due to it being the default mirror in our Docker image. Another
reason is so we can offer a link to our arch-boxes images in libosinfo
(used by gnome-boxes, virt-install and virt-manager), with good enough
performance for most users.

This time we take a different approach and use a DNS based solution,
which means the latency penalty is only paid once (the first DNS
request). The downside is that the mirrors must have a valid certificate
for the same domain name, which makes using third-party mirrors a
challenge. So for now, we are just using the sponsored mirorrs
controlled by the DevOps team.

Fix #101

Kristian Klausen authored 3 years ago and Jelle van der Waa committed 3 years ago

A extra access_log entry was added with the following commands:
$ cd roles
$ grep -lr access_log | xargs -P 1 -n 1 sed -i '/access_log/ s/\(.*\)\( \)\(\(reduced\|main\);$\)/\1 \3\n\1.json json_\3/'

Where http does not redirect to https. These are package mirrors and
the web key directory.

For proxy/fastcgi/uwsgi blocks, logging is still set to the old format,
but for everything else (= static data) a reduced format is used that
excludes items that no longer make sense (request_time, remote_user) and
those that are personal information all the time (remote_addr, http_x_forwarded_for).

This is the same as used on luna and as expected by the zabbix nginx
monitoring service.
