I use Wowza for many vod/audio streaming origin application. My cdn will cache chunk from Wowza origin server as user request. With .mp4 and .m4a extension, Wowza work well. With .mp3 extension, problem is: - with simillar streaming url, chunk ts is change by session (although i use origin setting), i check it by md5sum value. - my cdn cache chunk from many session and then user hear error audio. This is my link: [http://123.30.233.190/music\_audio3/_definst_/mp3:media1/song/web1/8/65555/65555.mp3/playlist.m3u8](http://123.30.233.190/music_audio3/_definst_/mp3:media1/song/web1/8/65555/65555.mp3/playlist.m3u8) my audio file [http://103.216.120.24:85/file/audio.mp3](http://103.216.120.24:85/file/audio.mp3) All config,log of wowza is total4.zip. My wowza is 4.6.0. a.zip and a1.zip is chunk of similar streaming link at diffirent chrome tab.
