>                 Key: FLINK-5109
>                 URL: https://issues.apache.org/jira/browse/FLINK-5109
>             Project: Flink
>          Issue Type: Bug
>          Components: Web Client, Webfrontend
>    Affects Versions: 1.1.0, 1.2.0, 1.1.1, 1.1.2, 1.1.3
>            Reporter: Móger Tibor László
>              Labels: http-headers, rest_api

> On REST API calls the Flink runtime responds with the header Content-Encoding, containing
the value "utf-8". According to the HTTP/1.1 standard this header is invalid. ( https://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.5
) 
> Possible acceptable values are: gzip, compress, deflate. Or it should be omitted.
> The invalid header may cause malfunction in projects building against Flink.
> The invalid header may be present in earlier versions aswell.
> Proposed solution: Remove lines from the project, where CONTENT_ENCODING header is set
to "utf-8". (I could do this in a PR.)
> Possible solution but may need further knowledge and skills than mine: Introduce content-encoding.
Doing so may need some configuration beacuse then Flink would have to encode the responses
properly (even paying attention to the request's Accept-Encoding headers).
