Long Polling middleware and client?

[nakasyou]

What is the feature you are proposing?

Most of web clients have supported WebSockets.

But currently, many proxies may be blocking WebSockets. It includes workplace and school proxies. Engine.io, as Socket.io core's README has such a description.

In my school, we often enjoy real-time web games for learning. Our school's iPad proxy is blocking WebSockets, but those games is able to working. I think the reason is those games is using Long Polling.

Other than this, I found many articles what workplace proxies blocked WebSocket, but I don't write it because articles is Japanese articles.

So I would like have Long Polling middleware. If Hono has this middleware, Hono may be "Web standard alternative to Socket.io"

Long polling is one of streaming-ish method.

SSE (Sever-sent Events) is another streaming technology and Hono offers server-side implementation. You may use SSE with EventSource in client side.

Hi @exoego, I think some proxies block SSE. At least in my school. But I can't find the source, I'm sorry.

Oh... then plain polling or long polling would be a rescue
