HTTP Response with two "Transfer-Encoding: chunked" headers -

i'm implementing client application using http-core consume http endpoint. while investigate little bit on endpoint response header fields find 2 transfer-encoding fields value of 'chunked'. after investigating little bit on http protocol spec i'm able found following section http://www.w3.org/protocols/rfc2616/rfc2616-sec3.html#sec3.6

according above resource, seems out of compliance. can little bit explain transfer-encoding header value duplication in response headers.

thanks

(what's relevant http://svn.tools.ietf.org/svn/wg/httpbis/specs/rfc7230.html#chunked.encoding)

i agree multiple "chunked" fields bug in server.

out of curiosity: chunked encoding indeed applied multiple times?
