Lawrence (and all),

I haven't gotten a chance to dig into the examples and work on the problem yet but I wanted to say thanks for the help.

For example: Is using the IP address as the key really a good idea?
Might an IP address be assigned to two different users -- or might a
person use two different user agents on one host?  Do you want to deal
with that?  Do you want the per-host to be a LIST of browser/flavor
pairs?

I think you're right. I'm not sure using the IP is the best approach. I'm thinking that beginning with a known list of robot user agents then watching for a pattern of successive pages being downloaded at a average frequency of not more than a couple seconds each might be a better approach.


I'm expecting to rewrite this a number of times as I test then find weaknesses in my approach, and the rewriting can only help with my understanding of Perl so I don't mind. (Kinda look forward to it, actually.)

Your homework:  Starting with that structure above, write a subroutine
that will iterate across it producing the following output:

I'll work on it, but it might take me a while. (I only get to work on programming for a couple of hours each night after everyone else has gone to bed.)


I really appreciate all the help everyone has offered.

Cheers,

James
