You options are:

(1) Shared filesystem between the two hosts to hold the static content

(2) Use nginx with caching proxy on the static machine
In this setup, a cache miss will result in a request for the static
resource from the dynamic server (which I assume is also capable of
serving static content). This should work as long you expect to have a
high cache hit ratio
