PUT and request parameters

To access the body parameters of a PUT request, one must add :PUT to hunchentoot:*methods-for-post-parameters*, which defaults to only (:POST):

(push :put hunchentoot:*methods-for-post-parameters*)

This parameter:

is a list of the request method types (as keywords) for which Hunchentoot will try to compute POST-PARAMETERS.

No such setting is required with Lack and Ningle.
