Response to: Why PUT vs. POST?
A PUT request is idempotent - it can be repeated and the client can be sure of the results. A POST has no such guarantee - it could append some text, and doing that twice results in something different than doing it once. The benefit of repeatable requests is that if the network goes down, or a reply doesn't reach the client, your software can simply send the request again - the system as a whole becomes tolerant of failures. In the example, the collection could be replace with a PUT, but that's a design choice of the developer.
