zentara has asked for the wisdom of the Perl Monks concerning the following question:

Hi, recently I posted a snippet to allow multipart attachment
downloads. I generated my own headers and it works fine with
linux apache and Mozilla. Merlyn reponded, that I could also
do it with CGI.pm. Well at the time, I didn't have the latest version
of CGI.pm, which supported the sub multipart_final, so I just
shoved the script to my code collection. I recently upgraded to
the latest CGI.pm and tried Merlyn's script again, and it just
refuses to run for me. I am asking for "higher guidance" now.
My working code follows
#!/usr/bin/perl use warnings; use strict; my $boundary_string = "\n" . "--End" . "\n"; my $end_of_data = "\n" . "--End--" . "\n"; my @file_list = ("test.tgz","test1.tgz","test2.tgz"); print<<EOH; Content-type: multipart/x-mixed-replace\;boundary=End EOH foreach my $file (@file_list){ &amp;amp;send_file ($file); print $boundary_string; } print $end_of_data; exit(0); sub send_file { my $file = $_[0]; if (open (FILE, "< $file")) { print<<EOF; Content-type: application/octet-stream Content-Disposition: attachment\; filename=$file EOF binmode FILE; print <FILE>; close (FILE); }else{print "Cannot open file $file!"} }

merlyn's suggestion follows below:
#!/usr/bin/perl use CGI qw(:push); @ARGV = ("test.tgz","test1.tgz","test2.tgz"); $/ = undef; print multipart_init(); while (<>) { print multipart_start("application/octet-stream"); print $_; print multipart_end(); } print multipart_final();
########################################
When I run Merlyn's code, the filename is always
nph-download-multi, and I'm prompted to save that
filename 6 times instead of 3, and the name is always
nph-download-multi, instead of test.tgz, test1.tgz, etc.
Now I did try to add a "-filename=>$_" to the code to
get the filename to come thru, but to no avail. Also the resultant
download is 0 bytes. I've tried every combination of header
that I could think of, but no luck. So would anyone be kind
enough to post a multipart-download script , based on CGI.pm
which actually works, so I can see what I'm doing wrong?
Thanks
