Description
The FrcaCtrlStart subroutine starts the interception of TCP data connections for an FRCA instance. If the FRCA instance cannot handle the data on that connection, it passes the data to the user-level application that has established the listen socket.
The only FRCA instance type that is currently supported handles static GET requests as part of the Hypertext Transfer Protocol (HTTP).
