- * Prevents consecutive form submissions of identical form values.
- *
- * Repetitive form submissions that would submit the identical form values
- * are prevented, unless the form values are different to the previously
- * submitted values.
- *
- * This is a simplified re-implementation of a user-agent behavior that
- * should be natively supported by major web browsers, but at this time, only
- * Firefox has a built-in protection.
- *
- * A form value-based approach ensures that the constraint is triggered for
- * consecutive, identical form submissions only. Compared to that, a form
- * button-based approach would (1) rely on [visible] buttons to exist where
- * technically not required and (2) require more complex state management if
- * there are multiple buttons in a form.
- *
- * This implementation is based on form-level submit events only and relies
- * on jQuery's serialize() method to determine submitted form values. As such,
- * the following limitations exist:
- *
- * - Event handlers on form buttons that preventDefault() do not receive a
- * double-submit protection. That is deemed to be fine, since such button
- * events typically trigger reversible client-side or server-side
- * operations that are local to the context of a form only.
- * - Changed values in advanced form controls, such as file inputs, are not
- * part of the form values being compared between consecutive form submits
- * (due to limitations of jQuery.serialize()). That is deemed to be
- * acceptable, because if the user forgot to attach a file, then the size of
- * HTTP payload will most likely be small enough to be fully passed to the
- * server endpoint within (milli)seconds. If a user mistakenly attached a
- * wrong file and is technically versed enough to cancel the form submission
- * (and HTTP payload) in order to attach a different file, then that
- * edge-case is not supported here.
- *
- * Lastly, all forms submitted via HTTP GET are idempotent by definition of
- * HTTP standards, so excluded in this implementation.
