Proxy musicstore/AudioFileStore:

murecom-gw4reader （以下简称 gw）可以反向代理 musicstore/AudioFileStore 为音频文件提供的静态服务，以便 mureaderui 访问。

AUDIO_PROXIES='foo=http://127.0.0.1:6666/bar/audio/,fuzz=...' go run . -listen-addr='127.0.0.1:7777'

启用代理后，gw 会 "Hijack" murecom 的响应，检查其中的音频文件链接， 如果匹配上了，则替换为代理链接（/ 开头的、gw 的 route path，加上 gw 的 host 来访问）：

# sourceUrl from murecom
http://127.0.0.1:6666/bar/audio/song.mp3

# response to client: replaced by gw
=> /audioproxy/foo/song.mp3

然后请求 {listen-addr}/audioproxy/foo/song.mp3 会反向代理到原来的 localhost 地址上：

# client request:
GET 127.0.0.1:7777/audioproxy/foo/song.mp3

# gw proxy it to the upstream:
GET http://127.0.0.1:6666/bar/audio/song.mp3
