NOTE:

1: http support = whether the libirary/framework handles both websocket/http request, so that they can be seaved from same address/port

2: long polling = either the library/framework handles both long polling/and native websocket. This also includes long polling fallback.

3: Concurrency model = some depends on language, library, or its dependent web server.
