hey all Mongers,

I'm trying to write a Perl CGI script that will upload an Excel file
using Apache on a HP-UX system.

I've been using some of the code from the perldoc part of and
some code from the O'Reilly book "CGI Programming", I'm lost...

All I want is a CGI script which will be called from a web page link
that will upload Excel files (or binary file in general), text files 
would be nice too, but at a minimum just binary files.

I can get text files fine.

I get this in the Apache error log:

[Wed Nov 27 14:34:56 2002] [error] [client] Premature end of
script headers: /opt/apache2/lib/cgi-bin/, referer:
[Wed Nov 27 14:34:56 2002] [error] [client] Server
closed socket during multipart read (client aborted?)., referer:

Can someone point me to some existing code that does this? Or for a laugh
you can look at this mess I've created. As you can see I've tried lots of

Thanks for ANY help....


#!/opt/perl5/bin/perl -w

use CGI;

$q = new CGI;

print $q->header();
