9.1 Safe and Idempotent Methods
9.1.1 Safe Methods
Implementors should be aware that the software represents the user in
their interactions over the Internet, and should be careful to allow the
user to be aware of any actions they might take which may have an
unexpected significance to themselves or others.
In particular, the convention has been established that the GET and HEAD
methods SHOULD NOT have the significance of taking an action other than
retrieval. These methods ought to be considered "safe". This allows user
agents to represent other methods, such as POST, PUT and DELETE, in a
special way, so that the user is made aware of the fact that a possibly
unsafe action is being requested.
Naturally, it is not possible to ensure that the server does not generate
side-effects as a result of performing a GET request; in fact, some
dynamic resources consider that a feature. The important distinction here
is that the user did not request the side-effects, so therefore cannot be
held accountable for them.
