"You say: generate a link, and if the user clicks on it, run the following code." Maybe I'm being dense here, but how is: (user state + resource state) -> link -> code different than: (resource state -> link) + user state -> code other than that in the first instance you're encoding user state in the control layer? In both cases you're mapping (user state + resource state) to a specific block of code. How does the order you do it in affect anything else?
