EnableHttpCompression doesn't work correctly

[darkfeanor]

NEST/Elasticsearch.Net version : 2.3.3

Elasticsearch version: 2.3.2

Description of the problem including expected versus actual behavior:
I'm trying to use the compression between Client and Server and getting the following Error:

"System.InvalidOperationException: Misused header name. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects".

I have used: "settings.EnableHttpCompression()"; at client and "http.compression:true" at server.

I'm using .net core rc1.

It seems to be a bug, or I'm making something wrong...

Hey @darkfeanor I'm not having any success reproducing this (on .net core 1.0 rtm)

Mind sharing a complete code snippet that's failing for you? Also, if you can paste the value of DebugInformation on the response here that would also be helpful.

Hi! Here is an Example of my code:

[Route("testES")]
[HttpGet]
public string testES()
{
var host = "localhost";
var port = "9202";
var node = new Uri("http://" + host + ":" + port + "/indexname/");
var settings = new ConnectionSettings(node);
settings.DisableDirectStreaming();
settings.EnableHttpCompression();
ElasticClient client = new ElasticClient(settings);
        var request = new SearchRequest()
        {
            Query = new TermsQuery() {
                Field = "Test",
                Terms = new string[] { "276055540680082", "528528001853706" },
                Name = "Test"
            }
        };
        var response = client.Search<object>(request);
        return "";
    }

And the DebugInformation:

And here is the content of elasticsearch.yml :

cluster.name: cluster1
http.port: 9202
transport.tcp.port: 9302 
http.compression: true

Thanks for reporting @darkfeanor I was able to reproduce this and opened the above fix.
