Hello, I'm using Wowza edge server (4.0.2) for HLS streaming. I secured url to streams with URL sign from WMSPanel. I have big problem with this. Access to main manifest (m3u8) is secured and can't be access without key send in URL query (http://x.x.x.x:1935/live/xxxxxxxxxxx?playlist.m3u8). Unfortunatelly, you can access stream with urls to next segments of stream (http://x.x.x.x:1935/live/xxxxxxxxxxx...852822719.m3u8). Those urls include Wowza session ID as I mean and only user who started session should have access to them. Is it kind of error in your HLS implementation. Is any way to avoid for this?
