I’m having some difficulty getting my cross domain policy to work. I have an rtmp streams at local Wowza Server.

I want to prevent connection from all servers except mine.

My crossdomain.xml is:

> \<?xml version="1.0"?\>

When I try to play streams from other server. Everything is playing. What’s wrong?

What kind of streaming are you doing and what do you want to prevent exactly. For RTMP, take a look at the MediaSecurity Addon
