in reply to Handling relative urls with LWP or something else

While you might want to keep merlyn's columns in mind as good reading and a source of (hopefully) good examples using common CPAN modules, you might also want to check the POD for URI. And I quote:

$uri = URI->new_abs( $str, $base_uri )
This constructs a new absolute URI object. The $str argument can denote a relative or absolute URI. If relative, then it will be absolutized using $base_uri as base. The $base_uri must be an absolute URI.

So if you know the URL of the page you got the URL from, you know $base_uri. A simple test like $url =~ /^http/ should let you know whether you've gotten an absolute URL or not. Of course, testing is not necessary as the constructor will gladly ignore the $base_uri if $str is absolute. Or so sayeth the POD anyway.

[MidLifeXis]: I have a user who has a lot of say on how some of our processes work that abhors significant blanks. Perhaps that is a part of it. A not-so-obvious "this space intentionally left blank" indicator.
[MidLifeXis]: On the back end, however, that doesn't mean that i have to use that value to indicate "undefined", no matter how much he thinks I should.
