The PUT method which can be used for resource creation or replacement is idempotent and can be used only for full updates. The edit forms used in conventional Ruby on Rails application need to create new resources by applying partial updates to a parent resource.
The HTTP/1.0 specification [49] defined the GET, HEAD, and POST methods as well as listing the PUT, DELETE, LINK and UNLINK methods under additional methods. However, the HTTP/1.1 specification [50] formally defined and added five new methods: PUT, DELETE, CONNECT, OPTIONS, and TRACE. Any client can use any method and the server can be ...
A sequence of idempotent subroutines where at least one subroutine is different from the others, however, is not necessarily idempotent if a later subroutine in the sequence changes a value that an earlier subroutine depends on—idempotence is not closed under sequential composition. For example, suppose the initial value of a variable is 3 ...

Non-idempotent requests such as POST should not be pipelined. [6] Read requests like GET and HEAD can always be pipelined. A sequence of other idempotent requests like PUT and DELETE can be pipelined or not depending on whether requests in the sequence depend on the effect of others. [1] HTTP pipelining requires both the client and the server ...
Per RFC 7231, the POST method is not idempotent, meaning that multiple identical requests might not have the same effect as transmitting the request only once.POST is therefore suitable for requests which change the state each time they are performed, for example submitting a comment to a blog post or voting in an online poll.
The RMM can be employed to determine how well a Web service architecture adheres to REST principles. It categorizes a Web API into four levels (from 0 to 3) with each higher level corresponding to a more complete adherence to REST design. The next level also contains all the characteristics of the previous one. [4] [5]
REST (Representational State Transfer) is a software architectural style that was created to guide the design and development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of a distributed, Internet-scale hypermedia system, such as the Web, should behave.
