Hi, I’d like to start discussing here on HyBi ML how we should evolve WebSockets. We’ve been thinking about this topic, and proposed WiSH [1] briefly at the HTTP WG (IETF 97 f2f) in Nov 2016. The HTTP-WG chairs suggested that this topic should be discussed within the WebSocket community. While HyBi WG is currently closed, this ML is still the best place to have this discussion. [Background] WebSocket (WS) is widely adopted. Popular sites such as GitHub, Slack, WhatsApp and Twitch are using WS. A majority of HTTP implementations now support WS, including client/server libraries, web frameworks and intermediaries. HyBi WG had been trying to evolve WS after finalizing the base WS protocol. Personally I have been the editor for the compression spec [2]. [WiSH] WiSH [1] is a general purpose message framing format for providing bi-directional message-based communication for the Web, considering compatibility with the WebSocket API and intermediaries. WiSH is applicable for any byte-stream oriented reliable wire protocols. Given the wide adoption of WS and the rapid evolution of HTTP, e.g. QUIC [3], we believe that the WiSH proposal creates an ideal evolution path for WS users, by leveraging the HTTP infrastructure and the widely deployed WS ecosystems at the same time. In designing the WiSH spec, we decided to layer WS framing as a MIME type over the standard HTTP semantics (v.s. any specific wire-transport version such as HTTP/1.1 or HTTP/2). WiSH will be made transparent to existing applications, i.e. WiSH doesn’t require extending or modifying existing APIs on the client or server side. WiSH can also automatically benefit from infrastructure support for HTTP/*, especially with guaranteed connectivity (no/less fallback needed). This makes the overall solution much more Web friendly and future proof We’d like to hear your feedback on the WiSH proposal and/or any general thoughts on how to evolve WS.
