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