Why don't use incron or other inotify based tool to pre-fetch the
assets? There's also http://wiki.nginx.org/HttpProxyModule#proxy_store
which IMO seems more adequate to your setup.

Other option is to use something like auth_request with a script or
the embedded Lua (http://wiki.nginx.org/HttpLuaModule) or Perl modules
(https://github.com/zzzcpan/nginx-perl) and do some scripting.
