Basic questions realted to Netty usage

[Bruno de Carvalho]

Kanksha,


Regarding your 1) question, I believe it is. I'd just advise you to add
the channels to the channel groups as soon as they are connected and not
only after SSL handshake completing.

About your point 2) really depends on whether you want to maintain
context/state per client. From what I understood, your architecture goes
like this.

client --> server --> processing module --> server --> client

Since you don't want to mix up responses to clients, I guess in your
case a server handler per channel would be more appropriate. Let me
elaborate:

With one handler per channel:
client1 -> srv[handler1] -> ProcMod -> srv[handler1] -> client1
client2 -> srv[handler2] -> ProcMod -> srv[handler2] -> client2

With the same handler for all channels:
client1 -> srv-handler -> ProcMod -> srv-handler -> 1 or 2?
client2 -> srv-handler -> ProcMod -> srv-handler -> 1 or 2?
