Want to add exception for a auto run sub in module

[Jimmy]

Hi all,

I have a module somewhat looks like this :

  package minicgi;
  require Exporter;  our @ISA = qw/Exporter/;
  our @EXPORT = qw/NormalHeader OtherHeader/;

  sub NornalHeader { print "Content-Type:text/html\n\n" } # normal html
  sub OtherHeader { print "Content-Type:$_[0]\r\n\r\n" } # perhaps sending file

   NormalHeader;
  1;


So, when I use minicgi, normal_header() will autorun, however, 
it makes the other_header() meaningless. So my question is, 
is there anyway I'll run normal_header() without specific argument, 
but don't run it if I pass whatever argument on the 'use' statement ?

Thank you very much,
Jim
