Server Side Google Analytics

I stitched together a bunch of posts from different sites to get a working setup for server-side google analytics with unique user tracking. This allows you to have a completely static (javascript-free) site and still get useful analytics data.

server {
    # all of your other config...
        userid         on;
        userid_name    uid;
        userid_domain  <<the domain you are using this on>>;
        userid_path    /;
        userid_expires 365d;
        userid_p3p     'policyref="/w3c/p3p.xml", CP="CUR ADM OUR NOR STA NID"';

        location / {
                try_files $uri $uri/;
                index index.html;
                post_action @analytics;

        location @analytics {
                set $ipaddr $remote_addr;
                resolver ipv6=off;
                proxy_pass<<your analytics UA- tag>>&cid=$uid_got&t=pageview&dh=$host&dp=$uri&dr=$http_referer&uip=$remote_addr;

Of course replace the <<the domain you are using this on>> and <<your analytics UA- tag>> with the appropriate data.
This will result in the server sending out a GET request with the client's info to the tracking URL for each page visit. It increases bandwidth used by your server but is a neat trick regardless.
