In contrast, the methods POST, CONNECT, and PATCH are not necessarily idempotent, and therefore sending an identical POST request multiple times may further modify the state of the server or have further effects, such as sending multiple emails. In some cases this is the desired effect, but in other cases it may occur accidentally.
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.
To introduce a disambiguation page only to differentiate the word idempotent used as an adjective and as a noun seems clunky. As a noun, it is in effect an abbreviation for idempotent element. For this, redirecting idempotent to Idempotence seems okay, as the article does deal with it and gives a link to the main article.

A primitive idempotent of a ring R is a nonzero idempotent a such that aR is indecomposable as a right R-module; that is, such that aR is not a direct sum of two nonzero submodules. Equivalently, a is a primitive idempotent if it cannot be written as a = e + f , where e and f are nonzero orthogonal idempotents in R .
