Hello,

I'm not sure about the 'ajax.php' file, as I've never needed to do 
anything special for it. Here's a basic configuration that works for me.

# Handle /
location / {
         try_files $uri $uri/ /rampage.php?$args;
         }

# Handle /rpc
location /rpc/ {
         rewrite ^(.*)$ /rpc/index.php/$1;
         }

# Caldav and Carddav rewrites
location ~* /.well-known/(cal|card)dav {
         rewrite ^ /rpc/ permanent;
         }

# Set expires headers for static content
location ~* 
.(jpg|jpeg|png|gif|ico|css|js|ico|gz|bz2|tbz|tgz|svg|svgz|mp4|ogg|ogv|webm|zip|rar|tar|txt|pl)$ 
{
         expires  30d;
         }

# PHP files
location ~ [^/]\.php(/|$) {

# Set the uwsgi modifier to PHP
         uwsgi_modifier1 14;
         include /path/to/uwsgi_parms;

# Pass to UWSGI
         uwsgi_pass unix://$socket;
         }

That configuration should work assuming you're not using the uWSGI 
chroot capability. If you are doing chrooting, let me know and I'll send 
a more complete configuration.
