Node.js proxy, dealing with gzip DEcompression

Question

The decompressor expects binary encoded input. The chunk that your response receives is an instance of Buffer which toString() method does by default give you an UTF-8 encoded string back.

So you have to use chunk.toString('binary') to make it work, this can also be seen in the demo.
