It did. Just to pass along some cool information, I did
something like the following. Assume I've already downloaded
a page $urlOne, and extracted a URL inside of it called
$url2. Suppose $url2 is relative. To make it absolute
and stuff the absolute URL into $url3, we can do

use URI;
my $url3 = URL->new_abs($url2,$urlOne)->canonical;

That's it. The URI library is smart enough to know that when
you type

print "URL3 is $url3\n";

you want $url3 to be a string; you don't need to do
$url3->as_string, though you could.

Just some helpful words, should they ever come in handy for
anyone.
