allow compression on query response with views.

How can I enable gzip compression for View response?
I was tried add header to HTTP request, for example:

wget -v -d --header="Accept-Encoding:gzip" "http://localhost:8092/price_cache/_design/offers/_view/price_breakdown?connection_timeout=60000&endkey=%5B%22MAD%22%2C1%2C20150211%2C1%5D&inclusive_end=true&reduce=false&stale=ok&startkey=%5B%22MAD%22%2C1%2C20150211%2C0%5D" -O ./price_breakdown.json

But it doesn't work, I receive json in response
