Issue compressing data frames using CompressorHttp2ConnectionEncoder

[Anuradha niroshan]

I have implemented a HTTP/2.0 server which supports compression using Netty 4.1.5.Final.CompressorHttp2ConnectionEncoder class which is used for HTTP data frame compression. It uses content-encoding Transport header field to identify the compression algorithm.

Suppose when I am acting as a transparent proxy, when I obtain an already compressed data frames from backend HTTP/2.0 server (Which has the content-encoding header), does the above mentioned class re-compress the already compressed content? If so what is the proper way to use CompressorHttp2ConnectionEncoder class so that it would ignore already compressed content.
