in reply to Initializing Hash Arrays in Perl

This is a hash of hashes of hashes (HoHoH), which could have content like:

$VAR1 = { '543210' => { '212' => { '' => 42 } } };

where the 543210 is a $campaign_id value, the 100 is a $skin_id value, and the is a $refr_url value.

Please forgive the guessing here, but it looks like the data structure might be used to track the frequency of a referring URL, based upon a(n) (advertising?) campaign id and skin id.

This structure might be queried to answer something like, "How many referrals came from during the 543210 campaign that involved skin 212?"

Hope this helps!
