How does one modify a script which functions satisfactorily in permitting a user to download files (from the server to the client using "save as"), so that some plain text/html can also be added into the application without said additions corrupting the operation of the download?

Consider the below script which works fine as long as one only wants to use it to download a file on the server.

But suppose we want the script to also do things like say 'Hello World' and 'Goodbye World' (at the places commented out in the script)?

My dilemma is header (-type=>'application/x-octet-stream') and header (-type=>'plain/html') don't play nicely together. I've researched perldoc CGI headers and write-ups about the RFC on HTTP to no avail. Monks please advise.

#! /usr/bin/perl -wT
use strict;    #force all variables to be declared before use
use CGI qw(:standard);    
use CGI::Carp qw(warningsToBrowser fatalsToBrowser); 
print header (-type=>'application/x-octet-stream', -attachment=>'test.
+bmp'); 
start_html ();
my $file_name = "file1"; 
open (INFILE, $file_name) || die ("Can't open ($file_name): $!");
