Yeah, with-out-str can be replaced to suit your data. I think

If you need scalability, two phase connect might be necessary.
1. Resolve a server name which client should be connected to.
If a client need to be connected to specific resource (chat room etc)
consistent hashing is useful.

2. Connect.
There's also aleph[1] which also uses netty. I'd suggest trying it, as
it encapsulates websockets and other means of transportation in a
clean way.
(Although I have no idea how well aleph scales)

I haven't hooked up that many clients, but I can recommend Webbit
(https://github.com/webbit/webbit) based on experience.

Hi Clojurians,
Does anyone have experience with serving WebSockets from Clojure, in
particular w.r.t. scalability? I'm evaluating server-side options for
handling a large number of simultaneous web clients (>100) and
wondering how well this scales.
I already hooked up Clojure to Netty and built a
