set-cookie header

Hi all, I have this cgi binary that generates a header like this:

Set-Cookie: hguid=56578; path=/; domain=.ifom-ieo-campus.it;
expires=Thu, 31-Dec-2037 23:59:59 GMT
Content-Type:text/html


It works on others apache servers but on my it goes into Internal server
error.
Which module/option should I activate to let this being correctly
displayed?

thanks
