Directly messaging client on active connection

[danvinci]

Hello!

First of all, thanks for creating this library - it is allowing me to build with Julia and having fun :)

I'm working on a setup that would have two Javascript clients communicate with a Julia server through websockets.
I have the following case work:

• client A -> asks data to server > server replies > client A notifies server of receipt
• client B -> asks data to server > server replies > client B notifies server of receipt

What I would like to do next is:

• Server pings client A about client B being ready, without client A having to ask every N seconds about it

Is this possible?

I'm saving the server handles in an array, and I can see the server status and active connections - I'm wondering if:

• there's a way I can keep track of which connection belongs to which client
• I could later send a message through those active connections

I'm passing identifiers in the messages that would allow for this, but I'm not sure how the 'connection' object could be handled.
I haven't found explicit mentions in the docs or examples on discourse.

I'm sure I can make the "ping server ever Nth seconds" work, with the server always being a "replier",
but as I'm learning while doing, I'm not sure if that is a best practice.

Any suggestion is welcome!

@quinnj not sure if this was encountered before, any insight from you would be appreciated! :)

Okay I found someone's solution in Discourse, seems that saving the 'ws' handler for a specific client (when they first connect) is sufficient)
