This is an experimental feature to allow connection to SparkSDR through standard websockets.It aims to provide all the features of cat control combined with access to audio and iq data.
There are a number of projects using it

- DX Cluster interface Google group
- Original discussion https://groups.google.com/g/sparksdr/c/zCPYaqpSyvE

There is a simple test page here sparkservetest.htm which also serves as documentation for the protocol. There is also some documentation here https://github.com/nricciar/sparksdr-websocket-demo/wiki/WebSocket-API
