[web-devel] A WebSocket library

[Greg Weber]

Hi yi,

WAI is and will always be designed for HTTP. Websockets is a different
protocol (even though it is normally initiated over HTTP). If there is a way
that makes sense to put it websockets into WAI, it can definitely be
considered. But I believe the current plan is to put Websocket support into
Warp. Haskell code re-use will be achieved through this Websockets library.
Does that seem reasonable to you?
