Description

CompressorFilter compresses 206 Partial responses. The result is not valid HTTP, and has no defined meaning. CompressorFilter should instead forward 206 Partial responses without modification.

Contributor guide

Research direction
Inspect the CompressorFilter implementation to locate where HTTP response status codes are checked. Add a check for status 206 and skip compression for those responses, forwarding them unmodified.
