Re: Securing file access

[robbin <robbin () drivesajeep com>]

Script the retrieval and just put the file out there, basically you have 
to open the file and put it to the web page with the appropriate header 
so that the user will be prompted for a download, save as pop box.  I've 
done this in perl,

   print header(-type=>"application/x-download",
               -attachment=>"$fullyqualifiedfilename",
               );
   open (DWNLD,"<$file");
   binmode(DWNLD);
   $/ = undef;
   my $zip = <DWNLD>;
   close (DWNLD);

   binmode(STDOUT);
   print $zip;

Hope example helps.
