Strange shopping cart, that :)

class Cart

def store id item amt qty
@storage[id] << {:id => id, :item => item, :amt => amt, :qty => qty}
end

def retrieve id
@storage.find_all do | s | if s[:id] == id end
end

end

Then just use CGI/WEBrick/whatever to parse the GET (or however
you do it) to get the data for these requests and do authentication.
