Hi ! This should work with a small change:

zfile        =>["$ENV{DOCUMENT_ROOT}/filename.zip"],
[download]

instead of

zfile        =>"$ENV{DOCUMENT_ROOT}/filename.zip",
[download]

From perldoc HTTP::Request::Common:

           The POST method also supports the "multi­
           part/form-data" content used for Form-based File
           Upload as specified in RFC 1867.  You trigger this
           content format by specifying a content type of
           "'form-data'" as one of the request headers.  If one
           of the values in the $form_ref is an array reference,
           then it is treated as a file part specification with
           the following interpretation:

             [ $file, $filename, Header => Value... ]

           The first value in the array ($file) is the name of a
           file to open.  This file will be read and its content
           placed in the request.  The routine will croak if the
           file can't be opened.  Use an "undef" as $file value
           if you want to specify the content directly.  The
           $filename is the filename to report in the request.
           If this value is undefined, then the basename of the
           $file will be used.  You can specify an empty string
           as $filename if you don't want any filename in the
           request.
