Hi,
I took a closer look at the issue in prelude.
Here is what I see:
1. Browser A accesses the echo application described in my blog
2. Browser B accesses the echo application described in my blog
Then I find that A and B can talk without issue.
3. Browser C accesses the API application as the one described below or
my blog
Both A and B does not get the message from C.
If A sends a message, then now, it will get the message from C and the
message just send,
But B will not get the the messge from C and the message just send by A.
But A and B can still talk without problem.
Look like there is a regression in this case even in prelude.
