What's an "Internal Server Error" and how do I fix it?

I've encountered a problem of Internal Server Error which doesn't seem told on this page...

I have a perl file which runs perfectly through my computer on the Unix server... but when I run it on a browser on my computer, it returns the 500 Internal Server Error...

1) chmod 755 is set for all required files, other files are running on the browser no problem. Thus, there should be no misconfiguration problem.
2) The perl file calls an ASP file from another server to generate some data for the perl file to create a text file on the Unix server.
3) I don't know why the 3 error logs mentioned above I found on the server, are all blank text files... probably the path to them are set wrongly.

I'm thinking if it's the "HTTP request->GET" problem which needed to be changed when running on browser rather than server?

Here's the file which has problem running on a browser.

#!/usr/bin/perl -w

use CGI::Carp qw( fatalsToBrowser );
use warnings;
use strict;
use CGI qw(:standard);
use CGI qw/escape/;
use LWP::UserAgent;

my $cgi_object = CGI->new();
my $url = 'http://mywords.ust.hk/STU/games/game_getdata_storyman.asp';
my $file = 'eotw_word_lists_storyman';
my $ua = LWP::UserAgent->new();

$ua->credentials(
'lc.ust.hk:22',
'Language Centre',
'mywords' => 'mmyywwoo'
);

#$ua->agent("Mozilla/7.0");
#$ua->proxy('http', 'http://10.1.0.1:8080/' );
my $req = $ua->request(HTTP::Request->new( GET => $url ));
my $content = $req->content;
my @lines = split("\n",$content);
chomp(@lines);

my $line;
#Sent to a text file
unlink($file);
sysopen (OUT, $file, 0755, 0755);

foreach $line (@lines){
print OUT "$line\n";
}
close(OUT);

Thank You Very Much For Having A Simple Explanation For A Simple Problem .

I may not understand a whole lot of what is going on with the whole internal error deal. I know I have one and it entails,

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
