1. create dir /var/lib/nginx/fastcgicache and make it readable by nginx

2. at the very begining of your /etc/nginx/sites-available/yoursite
file (i.e., before the first server { ... line) include these 3 lines:

   fastcgi_cache_path /var/lib/nginx/fastcgicache levels=1:2
   keys_zone=MYCACHE:5m inactive=2h max_size=1g loader_files=1000
   loader_threshold=2000;

   map $http_cookie $no_cache { default 0; ~SESS 1; }

   fastcgi_cache_key "$scheme$request_method$host$request_uri";

3. in the block where you pass the control to php-fpm (i.e., the block
were you put include fastcgi_params; fastcgi_pass ...;
fastcgi_param ...; and so on ) add these:

		fastcgi_cache MYCACHE;
		fastcgi_keep_conn on;
		fastcgi_cache_bypass $no_cache;
		fastcgi_no_cache $no_cache;
		fastcgi_cache_valid 200 301 10m;
		fastcgi_cache_valid 302 5m;
		fastcgi_cache_valid 404 1m;
		fastcgi_cache_use_stale error timeout invalid_header updating http_500;
		fastcgi_ignore_headers Cache-Control Expires;
		expires epoch;
		fastcgi_cache_lock on;


Done.
