Instead of checking wikipedia for a general definition of idempotency, check the RFC for the definition that applies to HTTP

9.1.2 Idempotent Methods

   Methods can also have the property of "idempotence" in that (aside
   from error or expiration issues) the side-effects of N > 0 identical
   requests is the same as for a single request.
