Hi monks My problem is that i get an error:

Missing base argument at C:/Perl/site/lib/HTTP/Response.pm line 93

The code around where it points me to in that module is 

 if ($req) {
        # if $base is undef here, the return value is effectively
        # just a copy of $self->request->uri.
        return $HTTP::URI_CLASS->new_abs($base, $req->uri);
    }

My problematic code is: 

my $url_name;
 my $base_url = "http://www.perlmonks.com/";
 
 for (my $c = 0; $c<=$rowcount; $c++) {
     $webcrawler->get($url_name);
     my @links = map { $_->[0] } $webcrawler->links; # get Links
     
     my $ext1 = ".pdf";
     my $ext2 = ".doc";
     my $ext3 = ".ps";
     my $ext4 = ".txt";
     
     @links = map { URI->new_abs( $_, $base_url ) } @links;
    @links = map { /^$base_url/ ? $_ : () } @links;
    @links = grep(!/$ext1|$ext2|$ext4|$ext3$/, @links);

There is more code but am pretty certain the fault comes from somewhere in here. I can't figure out the problem. Can anyone help? Thanks for looking
