Note that you might be better off sending Yaws questions to the Yaws
mailing list (https://sourceforge.net/projects/erlyaws/lists/erlyaws-list).

I'm not sure I understand what you mean by the event being sent to all
connected clients. Events are sent on specific client connections. Perhaps
you're saying that your server-side code for a particular resource is going
into SSE mode regardless of how a client accesses that resource?

                Is there any way to overcome this? is there any better way

What you're asking for is entirely possible. I'd recommend either emailing
the Yaws mailing list or just emailing me directly to get more help. I'd
like to see the code you're currently using so I can get a better idea of
what directions to give you.
