Dynamic Cache in Nginx

Server NGINX
1

Hello guys,

I’m trying to set some Expires in a lot of JavaScript that I got here,
but they are not static on filesystem, it is dynamic generated by a Java
application.

If I do this:

===================
location /bla {
root /tmp;
expires 30m;
}

And put some .js files inside /tmp/bla everything works fine.

But when I try to do this:

===================
location /script {
expires 30m;
proxy_cache cache;
proxy_pass http://localhost:8080;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
}

Does not work. The reply from the server is always 200, never 304 as it
should be.

What can I do to fix this?

I also tried to use nginx 1.3.3 with Etag support, but also only works
with static files :frowning:

Thanks!!

For conditinal requests to work (and 304 to be returned) you need
Last-Modified (and/or ETag) header in original response. Try
adding one in your application.
