intermediaries something more valuable than "this may change something." The other methods are more valuable to intermediaries because they say something about how failures can be automatically handled and how intermediate caches can optimize their behavior. POST does not have those characteristics, but that doesn't mean we can live without it. POST serves many useful purposes in HTTP, including the general purpose of "this action isn't worth standardizing."
1183: 1193: 350: 1203: 633:
POST only becomes an issue when it is used in a situation for which some other method is ideally suited: e.g., retrieval of information that should be a representation of some resource (GET), complete replacement of a representation (PUT), or any of the other standardized methods that tell

In HTTP, the GET (read), PUT (create and update), POST (create - if we don't have `id` or `uuid`), and DELETE (delete) methods are CRUD operations as they have storage management semantics, meaning that they let

CRUD is also relevant at the user interface level of most applications. For example, in address book software, the basic storage unit is an individual

method, on the other hand, is a process operation that has target-resource-specific semantics which typically exceed the scope of CRUD operations.

systems do not implement UPDATE, but have only a timestamped INSERT (journaling), storing a completely new version of the object each time.

in software applications, numerous other persistence layers exist. CRUD functionality can for example be implemented with
