NGINX Configuration: NGINX Configuration with PROXY

"PROXY_CACHE is general-purpose cache with automatic lookups before PROXY_PASS, expiration support and so on. It is usually what you need if you need caching capabilities. Lets see the configuration of proxy_cache on RHEL 5.x.

Enable GZip:

gzip on;

gzip_http_version 1.1;

gzip_vary on;

gzip_comp_level 6;

gzip_proxied any;

gzip_buffers 16 8k;

gzip_disable “MSIE [1-6].(?!.*SV1)”;

Configure port:

listen 88;

server_name localhost;

access_log logs/host.access.log main;

Cache Path Setup:

proxy_buffering on

proxy_cache_path /usr/local/cache/proxy levels=1:2

keys_zone=aeon:10m inactive=30m

max_size=256m max_size=1500m inactive=600m;

proxy_temp_path /usr/local/cache/temp;

proxy_buffer_size 4k;

proxy_buffers 100 8k;

client_body_timeout 10;

client_header_timeout 10;

keepalive_timeout 5 5;

send_timeout 10;

expires 5m;

Proxy pass setup:

proxy_pass http://192.168.2.201:80;

proxy_cache aeon;

proxy_cache_key $request_uri;

proxy_cache_valid 200 301 302 20m;

proxy_cache_valid 404 1m;

proxy_cache_valid any 15m;

proxy_cache_use_stale error timeout invalid_header updating;

Prevent caching following url:

# This will prevent chaching for all urls matching this pattern.

location ~* ^/(.*)/(.*)/DiscountShop$New$/ {

proxy_pass http://192.168.2.201:80;

proxy_cache aeon;

proxy_cache_valid any 0m;

expires 0m;

}

Static file path:

location ~* (css|js|png|jpe?g|gif|ico|swf)$ {

root D:/docroot/;

expires max;

}
