How can I get Content-Length header (Head request method)

I don't see any way to get that header in akk-http. That header is removed from header list in HttpResponse.

I know there are methods that return the contentLength from entity:

HttpEntity.contentLengthOption and HttpEntity.contentLength on strict entity.

But that both calls are based on entity itself, and that's not what I want.

In my case I'm sending the Head request to server(riak) to check if the object has proper size. I don't want to get the whole object using Get. That should be just a test.

That's how the response looks like:

curl -I "http://req-to-riak" HTTP/1.1 200 OK X-Riak-Vclock: a85hYGBgzGDKBVI82eqS92f/Ot/EwOT3PoMpkTGPleHKa8WLfFkA Vary: Accept-Encoding Server: MochiWeb/1.1 WebMachine/1.10.8 (that head fake, tho) Last-Modified: Fri, 12 Aug 2016 06:42:28 GMT ETag: "5IVrr7tsZp1O4FHLnMSc30" Date: Wed, 24 Aug 2016 12:53:32 GMT Content-Type: image/gif Content-Length: 290305

But akka still return 0
