It may be easier to have just the domain name passed in to the script and then the script can handle ALL of the prefixes itself.

Yeah, that sounds sensible.
Here is an example of how you might implement that approach:

#!/usr/bin/perl
use strict;
use warnings;
use LWP::Simple;

DOMAIN:
while (my $domain = <DATA>) {
    chomp($domain); 
    for my $protocol (qw/http https/) {
        next DOMAIN if test_url("$protocol://$domain");
        for my $sub (qw/www web/) {
            next DOMAIN if test_url("$protocol://$sub.$domain");
        }   
    }   
    print "Couldn't get anything from $domain\n";
}   

sub test_url {
    my $url = shift;
    print "Trying $url ...";
    my $ua = LWP::UserAgent->new(
        timeout     => 5,
        agent       => 'Mozilla/5.0',
        ssl_opts    => { verify_hostname => 0 },
    );  
    my $response = $ua->get($url);
    if ($response->is_success) {
        print "OK\n";
        return 1;
    }   
    else {
        print "FAILED because " . $response->status_line . "\n";
        return undef;
    }   
}   

__DATA__
google.com
apple.com
fred.com
dschjksdbckjqh.com

Output:

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
