You seem to suggest that you have some blocking configured, and that it
does not do all that you want.
What blocking do you have configured? It may be simplest to adjust that,
rather than try to add something new.
The two question marks in the url looks odd to me; but it is in both your
"bad" and "good" ones, so maybe it is normal.

You have $query_string, which is the same as $args. If you can define a
regex pattern which matches everything you want, you can return failure
for everything else.
Perhaps ($args !~ "&ttl=[0-9]*&\?$") is a suitable test condition in
Good luck with it,
