Defined in:
lib/em-http/decoders.rb

Overview

Oneshot decompressor, due to lack of a streaming Gzip reader implementation. We may steal code from Zliby to improve this.

For now, do not put ‘gzip’ or ‘compressed’ in your accept-encoding header if you expect much data through the :on_response interface.
