I have question
about caching functionality in nginx.
The purpose is to
use nginx on local server to speed up responses from <remote
server>.
1. Will the
following configuation cache static content from <remote server> for 5d
?
2. Where will the
cached content be stored ? Directory ../nginx/proxy_temp is always
empty.
"expires" just refers to how long items will remain in the browser cache.
Nginx cannot act as a caching proxy. There are a couple of ways to emulate
caching behavior if you control the remote server. One is to have the remote
server stuff its results in Memcached. See
http://wiki.codemongers.com/NginxMemcachedModule. Another solution is for the
remote server, upon receiving a request from Nginx, to send a PUT request to
Nginx where Nginx will find the file in the future, then reply to the initial
request with X-Accel-Redirect to the newly PUTted file. I do this for some image
files I want to dynamically resize and cache. My nginx.conf looks like:
location /images {
include conf/fastcgi_params;
if (!-f $request_filename) {
fastcgi_pass backend;
}
dav_methods put;
create_full_put_path on;
limit_except GET {
allow 192.168.0.0/16;
allow 127.0.0.1/32;
deny all;
}
expires max;
}
The advantages over the Memcache method is that MIME types will work out of the
box, the disk cache doesn't expire, and it's often faster.
Hope this helps.
