Hi all, We're using HTTP Client 4.x with httpclient-cache. Our system needs to retrieve some metadata over HTTP that is returned in a Header Field, so it only needs to make a HEAD request. However, as it stands httpclient-cache does not cache the responses to HEAD requests.
While the HTTP spec doesn't (by my reading) take a positive position on whether or not you can cache responses to HEAD requests, there doesn't seem any particular reason why they shouldn't be cached, with the obvious proviso that a GET request to a resource which currently only has a cached header must result in a request to origin, and that PUT, POST & DELETE requests should all invalidate the cache for that resource as usual. We're considering extending httpclient-cache to make this possible, but we don't want to lock ourselves out of upgrading forever. If we were to do so and offer to contribute it back to the project would you be interested?
