That's a helpful link - thanks! Although, that code uses an HTTP::Response object to pass back to the daemon. Any advice on printing out the response object when not using a daemon? The CPAN docs are entirely clear on this (HTTP::Response and HTTP::Message), and when I implement the print $response->decoded_content in the following code, I get an error of Can't decode ref content at /usr/local/lib/perl5/site_perl/5.8.9/HTTP/Message.pm line 294.

    use HTTP::Response;
    use IO::File;
    my $response = new HTTP::Response( 404,undef,undef,"404 - Not foun
+d." );
    
    $|=1;
    
    my $file = new IO::File "< $path";
    if (defined $file) {
        $response->code( 200 );
        binmode $file;
        my $size = -s $file;
        
        my ($startrange, $endrange) = (0,$size-1);
        if (defined $ENV{HTTP_RANGE} and $ENV{HTTP_RANGE} =~ /bytes\s*
+=\s*(\d+)-(\d+)?/) {
            $response->code( 206 );
            ($startrange,$endrange) = ($1,$2 || $endrange);
        };
        $file->seek($startrange,0);
        
        $response->header(Content_Length => $endrange-$startrange);
        $response->header(Content_Range => "bytes $startrange-$endrang
+e/$size");
        $response->content( sub {
            sysread($file, my ($buf), 16*1024); # No error checking ??
+?
            return $buf;
        });
    };
    
    print $response->decoded_content;

Another option I tried, just printing the HTTP headers and content to STDOUT, follows below. This prints the requested ranges using a Transfer-Encoding method of chunked, as described here: w3.org and here: Wiki. There are no server-side errors using this script, but the iPhone Safari client still shows a broken file.

        my @ranges;
        if($ENV{HTTP_RANGE} =~ s/^bytes=//i) {
            @ranges = split /,/, $ENV{HTTP_RANGE};
            print "Transfer-Encoding: chunked\n";
            warn "printing ranges @ranges\n";
        } else {
            print "Content-length: $filesize\n\n";
        }
        if(@ranges) {
            open my $fh, '<', $path;
                foreach $range (@ranges) {
                    my($begin, $end) = split /-/, $range;
                    print "Content_Range: bytes $begin-$end/$filesize\
+n\n";
                    my $whence = ($begin)? 0 : 2;
                    my $position = ($begin)? $begin : 0 - $end;
                    seek $fh, $position, $whence;
                    if($end) {
                        $range = ($begin)? $end - $begin : $end;
                        my $chunk_header = sprintf("%x", $range);
                        print "$chunk_header\r\n";
                        sysread $fh, $_ , $range;
                        print "$_\r\n";
                        warn "printed range of $range bytes from $begi
+n to $end\n";
                    } else {
                        while(<$fh>) { print }
                    }
                }
            close $fh;
            print "0\r\n";
        } else {
            open(FILE, $path) or die;
                while(<FILE>) { print }
            close(FILE);
        }
