How many edge server can configure ?

Hi,

I'm running AMS5.0 without no issue. But the problem is, Third person who have insert one server and serve to his client without my knowledge. Few days back only I have found using the traffic pattern.

My Actual Setup :

Core server [ Vhost - local] -- > Edge server [ Vhost - remote] --- > Clients

Third person who using my feeds :

Core server [ Mine ] -- > Edge server [ mine ] ---> Third person fms server [ Unauthorized person ] --- > Unauthorized Clients [ Third person clients ]

Please help me to solve this problem. Somewhere back-hole there is my configuration.

Thanks.
