Support for broadcasting

[OlivierSohn]

Hello,

First, thanks for providing this library, it's very helpful!

I'm using it in the context of a multiplayer-game where I often send the same data to many clients at once.

To do that efficiently, I can write this function to factor the serialization of the data:

sendNBinaryData :: WebSocketsData a => [Connection] -> a -> IO ()

And I wonder if it would be theoretically possible to also factor the compression of the messages (in the library)? Or is some client-specific information included in the message that makes every message different, and makes this factorization impossible? (I'm not very familiar with networking protocols)

Thanks!

Something should be possible with per package compression (and not the stream).
But there are no API calls for sendUncompressed and sendPreCompressed

@tolysz when you say 'package', do you mean a in

sendNBinaryData :: WebSocketsData a => [Connection] -> a -> IO ()

?

Also I'm not sure to understand what sendUncompressed and sendPreCompressed would do, can you give an example / explain a bit more the semantics?
Thanks!
