I'm having the same issue with cache being browser dependent. I've tried
setting up a crawl job using wget --recursive with Firefox and Chrome
headers, but that doesn't seem to trigger server-side caching either.


I'd like cache to be browser agnostic.

Any ideas?

It is hard to identify problems without getting a look at the configuration but for the sake of general ideas:

For one particular case of static file caching we use nginx's proxy_store feature ( http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_store ) - the files are literally stored as is (in the same tree structure/naming) on the cache server.

The configuration is way simple:

proxy_ignore_client_abort on; // optional

upstream backend {
  server 10.10.10.10;
}

server {
    root /path;
    error_page      404 = @store;

    location @store {
       internal;
       proxy_pass           http://imgstore;
       proxy_store          on;
    }
}


Obviously there are some drawbacks (or advantages in some cases) in caching this way - the expire headers (or any other headers for that matter) from the backend (or the client) have no effect on the cache server, the cache management (purging items / used space) is fully your responsibility, 404 (or any other non-200) responses are not cached (which might or might not be a problem).
