Ok, your solution looks better than mine... but I have no idea how to
interpret that, time to consult some manuals.
OK - following on from this, I'm doing a similar thing to the OP to
analyze my proxy's traffic (never occured to me to do it in a db until
that post)
I've done the above regex to pull out the domain part of the URL and am
left with results such as:
"acvs.mediaonenetwork.net"
"profile.ak.facebook.com"
"www.bankwest.com.au"
What I want to do next is pull out the major domain part of the URL
I.e. for the above three records I should end up with
"mediaonenetwork.net"
"facebook.com"
"bankwest.com.au"
What would be the best way to do something like that? I assume it won't
be a simple regex like the above due to the country codes on the end of
some domains. My thought is look at the last portion of the domain, if
it's 2 characters long then assume it's a country code and grab the last
three sections, if it's not three characters long then assume it's an
international domain and grab the last two... but that sounds a bit dodgy.
