Description

Hi compiled Nginx 1.13.9 from master branch to try out HTTP/2 Server Push but noticed the pushed assets loose their gzip compression and are served as non-compressed assets instead of compressed assets. Confirmed with Chrome devtool network inspection, nghttp tool and webpagetest.org that pushed assets are uncompressed. Seems similar to mod_h2 bug at https://github.com/icing/mod_h2/issues/86
