Browser Caching with Rails 4.0.2 with Nginx and unicorn


#1

I am facing an issue with rails application deployed on Amazon with
nginx
and unicorn. I am not using any controller or action to render a view,
rather I am using a simple html page inside a sub folder of public
folder
named html_app. And all the css, js and images are kept inside that
html_app folder with the same name. see below:
public/html_app/js/test.js
public/html_app/css/test.css
public/html_app/img/test.png
public/html_app/index.html

In order to use browser caching, I have given below configuration for
nginx
in config/nginx.conf, see below:

upstream unicorn {
server unix:/tmp/unicorn.cache_app.sock fail_timeout=0;
}

server {
listen 80;
server_name x.x.x.x;
root /home/ec2-user/cache_app/public;

location ^~ /home/ec2-user/cache_app/public {

gzip_static on;

expires max;

add_header Cache-Control public;

}

location ^~ /.(jpg|jpeg|gif|css|png|js|ico)/ {

gzip_static on;

expires 1d;

add_header Cache-Control public;

add_header Last-Modified “”;

add_header ETag on;

break;

}

try_files $uri/index.html $uri @unicorn https://github.com/unicorn;
location @unicorn https://github.com/unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn;
}

error_page 500 502 503 504 /500.html;
client_max_body_size 20M;
keepalive_timeout 10;

}

Everything is working except, expires in location block, if I define
expires globally, it works, but not inside the location.

Please suggest, where am I wrong ?

Thanks

I’m a little rusty on this, but i think it’s your regex. you definitely
need a $ sign. as it’s written, it will match only the filenames .jpg,
.peg, etc (filenames that actually have only those four characters). I
also seem to remember the ^~ is used when specifying directory entries
vs
regex expressions. The following might work

location ~* .(jpg|jpeg|gif|css|png|js|ico)$ {
