37 // If you want your service to be proxied you have to enable it (default
38 // disabled) and define an accepable list of proxies that are allowed to
39 // proxy your service.
41 // Add each allowed proxy definition object. For the normal CAS_ProxyChain
42 // class, the constructor takes an array of proxies to match. The list is in
43 // reverse just as seen from the service. Proxies have to be defined in reverse
44 // from the service to the user. If a user hits service A and gets proxied via
45 // B to service C the list of acceptable on C would be array(B,A). The definition
46 // of an individual proxy can be either a string or a regexp (preg_match is used)
47 // that will be matched against the proxy list supplied by the cas server
48 // when validating the proxy tickets. The strings are compared starting from
49 // the beginning and must fully match with the proxies in the list.

75 // moreover, a PGT was retrieved from the CAS server that will
76 // permit to gain accesses to new services.
