i see what you want to do, but i think we drift out of scope of this library. i think we should not test if we correctly configure nginx, only if the proxy client properly communicates with nginx. for the expire test, i would prefer to simply drop that, as it has nothing to do with the php side.

doing a test suite for nginx configuration examples sounds like an interesting idea, but imho should be a separate repository. otherwise we end up with too many things to maintain here.

can we do like this and remove this test and the additional files?
