Perhaps it's clearer if you think in terms of the context of these
various params():

o Query params carry temporary data from the web client to the web
server (i.e. from the user to your app)

o CGI::App params hold temporary data in your app for the duration of
its instantiation

o CGI::Session params hold permanent data (within reason) outside and
beyond the lifetime of one instantiation of your app. Hence they can be
used to pass data from one instantiation to the next, with access keyed
by session id. Hence you need to pass the session key from one
instantiation to the next. Hence our discussion of the various ways in
passing that session id (cookies, hidden form data, rewriting URLs)

So, these params() are not directly related to each other at all.
