The basics of tmpfs are here: http://en.wikipedia.org/wiki/Tmpfs

Here's my config with most comments and white-space trimmed out:
________________________________________
worker_processes 4;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;

events {
worker_connections 1024;

#normalize all accept-encoding headers to just gzip or empty string
set $myae "";
if ($http_accept_encoding ~* gzip) {set $myae "gzip";}
#get rid of accept-encoding header for known-compressed file types
#we only want to store one version of these files in cache
if ($uri ~* \.(gif|jpg|jpeg|png|pdf|swf|flv|mp3|mp4|wmv)$) {set $myae "";}
access_log /var/log/nginx/localhost.access.log;

location / {
proxy_pass http://backend;

proxy_cache_key "$host$request_uri$myae";
}
}

Thanks!!!!

So this is only caching gif|jpg|jpeg|png|pdf|swf|flv|mp3|mp4|wmv? That's almost exactly what I want.

Upstream backend is the ip address of what nginx is running on? This box has 4 IPs for 4 different sites, should I list them all in upstream backend?
