CGI::AJAX and header

Dear all:
just wondering if someone can help me with this module: question - is
there a way to prevent the module from printing out its own ie disable
header()

-- the reason is because I usually print $cgi->header all the way in
the beginning of my script -- and would want to use this module for
specific instances -- and would not need the header to printed again.

thanks in advance.
al ;)
