FpcRequestType Enumeration

The FpcRequestType enumerated type contains values that specify the types of requests used for connectivity verification in the FPCConnectivityVerifier and FPCConnectivityResult objects.

typedef enum FpcRequestType {
  fpcHttpRequest   = 0,
  fpcPingRequest   = 1,
  fpcTcpConnect    = 2
} FpcRequestType;

fpcHttpRequest
Connectivity is verified by sending an HTTP GET request for the specified URL and waiting for a reply. A reply received after a time interval that is below the round-trip time threshold indicates that the Web server is running and can be reached by Forefront TMG.
fpcPingRequest
Connectivity is verified by sending an ICMP ECHO_REQUEST packet to the specified server and waiting for an ECHO_REPLY packet from the server. A reply received after a time interval that is below the round-trip time threshold indicates that the server is running and can be reached by Forefront TMG.
fpcTcpConnect
Connectivity is verified by sending a TCP SYN packet to request a TCP connection to a specific port on the specified server and waiting for a SYN-ACK packet from the server. A reply received after a time interval that is below the round-trip time threshold indicates that a specific service is running on the server and can be reached by Forefront TMG.
