Hello Wowza Support ,

We are offering IP radio service with WowzaStreamingEngine.

We are planning to change the configuration to the Origin-cache because of traffic increase.

However, when we change to Origin mode, index file names will become sequential and chunkfile will be more easily stolen.

The authentication module we developed can’t not protect the chunkfile in order to protect only the playlist.

Would you teach me how to randomize Index file names in Origin mode?
