Responding to a Login Request via POST
In addition to the traditional CAS protocol, CAS3 and above support an additional attribute sent with the login request.
By appending method=POST to a login request, such as:
https://my.cas.server.com/login?service=foo&method=POST
tells the CAS server to send the response back to the service "foo" via POST instead of GET.
