node-http-proxy plus a REST API
configurable-http-proxy (CHP) provides you with a way to update and manage a proxy table using a command line interface or REST API. It is a simple wrapper around node-http-proxy. node-http-proxy is an HTTP programmable proxying library that supports websockets and is suitable for implementing components such as reverse proxies and load balancers. By wrapping node-http-proxy, configurable-http-proxy extends this functionality to JupyterHub deployments.
