Setting The Cookie Domain
Browsers enforce the rules stated by RFC 2965 for sending cookies to servers. If the cookie's domain is not set when the browser receives the cookie, that cookie is associated with the server that sent the cookie. If the cookie's domain has been set but does not match the name or the domain suffix of the server, then the browser does not send the cookie. Therefore, not having the correct cookie domain can lead to failure in maintaining a PeopleSoft session.
The cookie domain value is configured in web server-specific configuration by the PeopleSoft Internet Architecture setup if the Authentication Token Domain value has been entered. If this field was left blank during PeopleSoft Internet Architecture setup, either re-install PeopleSoft Internet Architecture or configure the cookie domain manually in the web server-specific configuration.
