my @logfolders=("accesslogdir","logs");
my @cgifolders=("cgi","cgi-bin","scripts");
my @cgifiles=("script.pl","test.pl","tools.pl");
my $baseurl="http://www.testurl.com";

for my $folder ( @logfolders, @cgifolders, '' ) {
    for my $file (@logfiles) {
        (my $combURL = "$baseurl/$folder/$file") =~ tr[/][]s;
