 A client for the [Server-Sent Events](https://www.w3.org/TR/eventsource/) protocol. This implementation runs on a worker thread, and uses the [`http`](https://rubygems.org/gems/http) gem to manage a persistent connection. Its primary purpose is to support the [LaunchDarkly SDK for Ruby](https://github.com/launchdarkly/ruby-client), but it can be used independently.
