Forum OpenACS Development: Re: Allow Host Node Mapped Host Names for Cookies
my message was just: think twice, when using domain cookies.
To your original question: yes, there should be a way to set optionally a cookie domain for host-node-mapped sites for orthogonality, but that should be possible from the web ui.
The second point was: the cookie-name confusion can be avoided, when we set e.g. a "cookie realm", like "development", "external", ... which could be appended to the cookie name (e.g. "ad_login-external", then there can't be any kind of confusion like indicated above.
