Optional callback URL to obtain a proxy-granting ticket from CAS.
This callback URL belongs to the Acegi Security System for Spring secured application. We suggest you use
CAS' ProxyTicketReceptor servlet to receive this callback and manage the proxy-granting ticket list.
The callback URL is usually something like
https://www.mycompany.com/application/casProxy/receptor .
If left null , the CasAuthenticationToken will not have a proxy granting
ticket IOU and there will be no proxy-granting ticket callback. Accordingly, the Acegi Securty System for
Spring secured application will be unable to obtain a proxy ticket to call another CAS-secured service on
behalf of the user. This is not really an issue for most applications.
