[mod_python] the domain name in mod_python's session/cookie management

Hi All,

When a new session/cookie is created on mod_python side, from the source 
code (mod_python/Session.py, mod_python/Cookie.py), I don't see how 
mod_python sets the domain name for the Set-Cookie http header.

Without the domain name, the cookie set in the browser is useless (at least 
in IE).  How does it work?  Am I missed anything?

Any help or input is appreciated.

Thanks.
