This is a radical document: ------------------------------------------- A simple method is a method that is `GET`, `HEAD`, or `POST`. There are no restrictions on methods. `CHICKEN` is perfectly acceptable (and not a misspelling of `CHECKIN`). Other than those that are normalized there are no casing restrictions either. `Egg` or `eGg` would be fine, though uppercase is encouraged for consistency.
