In the typical usage of HTTP, the GET and POST verbs seem to get the most mileage. I’ve previously covered some aspects of moving up the Richardson Maturity Model scale. Implementing the PUT and DELETE verbs is typically a step up to RMM Level 2. There are other HTTP verbs, outside of the ‘by the book’ RESTful patterns, which can prove very useful in certain situations. One of the easiest to implement verbs, with some great benefits in scaling terms, is the HEAD verb.
