use epoll; 
worker_connections 1024; 
} 
http { 
include mime.types; 
default_type application/octet-stream; 
access_log logs/access.log main; 

sendfile on; 
#tcp_nopush on; 

#keepalive_timeout 0; 
keepalive_timeout 65; 

proxy_temp_path /home/se/nginx_cache/tmp_nc1 1 2; 
proxy_cache_path /home/se/nginx_cache/nc1 levels=1:2 keys_zone=nc1:50m; 

upstream bj{ 
server 192.168.1.107:7111;
