New CPL format gestures have been added to ProxySG as of SGOS 22.214.171.124 for enabling/disabling HTTP handoff to Flash (RTMP) proxy.
Here is CPL action usage: streaming.rtmp.http_handoff(auto|yes|no)
Auto: Implies that when this action is triggered, the request will use whatever is set globally for HTTP handoff in Flash proxy. Yes: Enables HTTP handoff when the action is triggered. No: Disables HTTP handoff when the action is triggered.
