+Default RT's session cookie to not being directly accessible to
+javascript. The content is still sent during regular and AJAX requests,
+and other cookies are unaffected, but the session-id is less
+programmatically accessible to javascript. Turning this off should only
+be necessary in situations with odd client-side authentication

+
+If set to a false value, the HTTP C<Referer> (sic) header will not be
+checked to ensure that requests come from RT's own domain. As RT allows
+for GET requests to alter state, disabling this opens RT up to
+cross-site request forgery (CSRF) attacks.

+=item C<$RestrictLoginReferrer>
+
+If set to a false value, RT will allow the user to log in from any link
+or request, merely by passing in C<user> and C<pass> parameters; setting
+it to a true value forces all logins to come from the login box, so the
+user is aware that they are being logged in. The default is off, for
+backwards compatability.
