High-level access is performed using a set of types that implement a generic request/response architecture, which is extensible, to support new protocols. The implementation of this architecture in the FCL also includes HTTP-specific extensions to make interacting with web servers easy.
Should the application require lower-level access to the network, types exist to support the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Finally, in situations in which direct transport-level access is required, there are types that provide raw socket access.
