Nginx Proxy Cache and Tomcat

Hello,
We need a little bit of help to understand what's wrong with our
config.
We try to setup a reverse proxy cache using Nginx but somthing seems to
be wrong with our configuration.
Behind the Nginx there is a tomcat server.
The problem is that Nginx doesn't cache at all.
Logs shows that the content isen't cacheable, but we diden't understand
why !!
The config is:
nginx -V
nginx version: nginx/0.8.53
built by gcc 4.4.3 20100127 (Red Hat 4.4.3-4) (GCC)
configure arguments: --with-debug
nginx.conf
worker_processes 2;
error_log logs/error.log debug_core debug_http debug_alloc debug_mutex
debug_event ;
worker_rlimit_nofile 8192;
events {
worker_connections 1024;
use epoll;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
