NOTE: it is often practical to use the generic (s:get-inp ...) which
will first look for the POST input variable and then fall back
to the GET param. This allows one to switch back and forth
between GET and POST during development without changing the code.
(s:get-inp 'param1) ;; trys to find input by name of param1, followed by trying get-param
