I have a page
sse.php that read data and send it back to client.
It works well except it starting over every N seconds.
I understand that EventSource reconnecting every N seconds
and my php script is started over again and again.
How do i determine what connection is the first one and what are just a maintaining reconnection?
Then i would know on what connection to run the reading script and on what not.
On WebSockets i know it is connecting only once then i only send data.
How to acquire the same with SSE?
