http.cors ES 2.3

[chanserv]

Elasticsearch version:
2.3
JVM version:
1.8.0
OS version:
Windows 7
Description of the problem including expected versus actual behavior:
I have set cors conf in elasticsearch.yml like this
http.cors.enabled : true http.cors.allow-origin : "*" http.cors.allow-methods : OPTIONS, HEAD, GET, POST, PUT, DELETE http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type, Content-Length

When requesting elasticsearch from file:///C:/elastic/index.html i got the following error
Request header field Content-Type is not allowed by Access-Control-Allow-Headers

I switched to 2.2 version and i set the same parameters and it works like a charm

Steps to reproduce:
1.Set cors parameters in elasticsearch.yml
2.Request elasticsearch from an url like this: file:///c:/..
