You can get off-the-shelf libraries that do this for you with zero-effort sane defaults. Most of them let you tweak the settings. I'm talking about Python's `requests` and Rust's `reqwest` here btw, two of the most popular HTTP client libraries out there. Python's `urlopen3`, which `requests` uses, exposes options for backoff strategies. `aiohttp` has a lot of these parameters as well. Unfortunately Rust's equivalent, `hyper`, isn't nearly as ergonomic/easy to use.
