A "location" match does not involve the query string -- that is, it
stops looking before the ?. So no "location" block can match adv_id in
the query string.

You could do something like

  if ($args ~ "adv_id") {}

to set a variable, and then later cache (or not) based on that variable.

But if you don't like "if", you'll want to come up with another way of
doing something similar. Perhaps "map"?

Does adv_id ever appear outside of the query string, where a "location"
could match it? If so, you may want to use $request_uri instead of $args.
