Really?

Your url has 18 hex characters. Your rewrite rule will only match if
there are 20. And "[a] => ad" doesn't appear anywhere in your url.

Here your rewrite rule will only match if there are 18 hex characters.

I expect

[a] => a6 [b] => 69 [c] => 164f02f6fdc18f

Be consistent.

How long is the url you want to test? Make sure you match exactly that
many characters in your rewrite rule.
