(Welcome to StackExchange.NetGain!
Warning: reduced maintenance
A few things have changed since this library was written:
- "pipelines" have become the new hotness for high performance low overhead IO code - see my 3-and-a-bit-part series here
- "Kestrel", combined with pipelines, now provides a great hosting experience for high volume servers
- HTTP/2 (and above) have reduced the usefulness of web-sockets (one of the main drivers for me and NetGain), since the web-sockets drafts for HTTP/2 never really "took"
As of late 2018, Stack Overflow (Stack Exchange) have migrated away from NetGain, instead using Kestrel's inbuilt web-socket support over HTTP/1.*; it is entirely possible that as we delve more into HTTP/2, we look more in the direction of SSE (EventSource).
So: we're not actively working with, or working on, this library. If you have a burning desire to take it further as an official maintainer (perhaps with some tweaks to naming, obviously) - let me know!
NetGain supports:
- RFC 6455
- all draft versions of the RFC (between hixie-76 and v13, aka RFC 6455)
- hixie-76/hybi-00
- fixes for various browsers with slightly broken implementations
