Not really relevant to the problem, just some "protips":

(remove-if-not (lambda (x) (string= (car x) "task[]")) (hunchentoot:get-parameters*))
=>
(remove "task[]" (hunchentoot:get-parameters*) :key #'car :test #'string/=)

But with mapcar #'cdr combined, it'd be better:
(loop for (key . value) in (get-parameters*)
      when (string= key "task[]")
      collect value)
