Foxy-Pools support several connection methods to use by miners and use Socket.IO to connect to the Web-UI.
- Socket.IO, a library that enables real-time, bidirectional and event-based communication between client and server.
- plain Websockets
- HTTP polling
Socket.IO and plain Websockets allow for low-overhead communication without the need for polling for new mining info or the latest pool stats. Instead one can subscribe to topics one wants to be kept up-to-date with.
