IC does check the IP address if the session is not cookie based, so
spoofing the cookie would be required to hijack the session, unless
someone can guess the session ID of someone else on the same IP (think a
NAT situation such as a cyber cafe) or you disable or weaken IP checking
via one of the config directives mentioned by Kevin earlier.
