Could you elaborate a bit more in depth about this, maybe the problem you are trying to solve as well as how you'd think it should look like?

Closing as invalid, since the issue template was removed.

It seems to me the original reporter is saying that HEAD requests should be handled as GET requests, just adding a req.method !== 'HEAD' to the conditional. It seems to me this wouldn't be harmful, but it may be nice to respond with empty content for a HEAD request. Currently I'm putting a another middleware in front of this to handle HEAD requests.
