When I do this locally, I get more headers:

Trying this against a Metacat Member Node, it works fine:

curl -v -X HEAD -k -o - "https://knb.ecoinformatics.org/knb/d1/mn/v1/object/Akasha.9.1"
...

Trying against the CN, we get the error:

curl -v -X HEAD -k -o - "https://cn-ucsb-1.dataone.org/cn/v1/object/Akasha.9.1"
...

So, we need to look at this from the CN proxy perspective. We know that Metacat is producing the correct HTTP header since this is shared code between the MN and CN (D1NodeService), and so we need to do the same test where we enable http.wire logging on the CN to see where we might be losing the header.
