This change allows the cooking server to communicate with clients using platform-specific communication protocols instead of TCP (the default). This new mode is activated by adding '-platformprotocol' command-line parameter when starting the cooking server (in addition to the usual '-cookonthefly'). The new functionality is included in FNetworkFileServerPlatformProtocol, which is a variant of the preexisting FNetworkFileServer but using ITargetDevice/ITargetDeviceSocket interfaces instead of traditional sockets. Direct communication with targets is only supported on some platforms, which can be checked by calling ITargetPlatform::SupportsFeature(ETargetPlatformFeatures::DirectDataExchange). #rb jeff.newquist #preflight 62166a4237178b0175af6269 [CL 19094838 by Wojciech Krywult in ue5-main branch]
