A Resilient Web API Client in Ruby

Ruby HTTP client is not sophisticated enough to handle errors gracefully. I came across a well-designed client for a web service at [AppSignal].
(https://blog.appsignal.com/2018/05/16/ensure-retry-and-reraise-exceptions-in-ruby.html)

The code for the client is as following:

The code has the following logic:

  1. Try to establish a connection with the server.
  2. The request has a timeout and connection refused exceptions.
  3. If retries fail, code raise the last seen exception.
  4. Each retry has increased timeout.
