Thanks for the answer.
The server and teh client are on the same subnet a few (30) feets between. It is an SSE server so it is transmitting continously. I do not need to refresh teh webpage it just print. I was needing to get the data in a small microcontroller ( Arduino, ESP and alike) and if possibly in a zigbee network in order to control some home automation .
I think I solved the problem by using GetStreamPtr with an ESP8266.
It seems to work fine.
