As I see it, we basically have two possibilities here:

1. Make the URLs distinguishable;
2. Add additional metadata in a non-URL place

1 is undesirable because it ruins caching, and we like caching. So we
look at 2, which realistically means the x_analytics field. Why don't
we add a parameter there? refresh=1. And then, our app check boils
down to (in pseudocode):

if(other_checks & urlContains("sections=(0|all)" &
!xAnalyticsContains("refresh")){
    return true;
}
return false;

Nice and simple and easy. It'll require some coordination with
Ottomata because it means modifying the UDF parameters, and we're
using said UDF in production so it'll have to be synced to a change in
the relevant Oozie job, but it should be totally doable, and I can't
see an easier way of doing it.

Thoughts, people?
