Yes, though this requires some special configuration. In
particular, you have to instruct your backend to return gzip
(usually by "proxy_set_header Accept-Encoding gzip;" in nginx).
Additionally, if your backen returns "Vary: Accept-Encoding",
you'll have to instruct nginx to ignore it when using nginx 1.7.7+
("proxy_ignore_headers Vary").
