Communication with the Wowza server HTTP caching origin is sessionless (session-based communication doesn't work). A single session is created internally for the requested protocol. This session is based on the stream name and it's used for every request for that name. This has the following ramifications:
URL query parameters in player requests aren't supported. This includes the wowzaplaystart and wowzaplayduration parameters for VOD playback, the wowzadvrplayliststart and wowzadvrplaylistduration for nDVR playback, and any custom parameters. (This does NOT include the DVR query parameter that's required for DVR playback.) If query parameters are set, only the parameters that are set when the stream name is initially requested are used. Subsequent changes to these parameters, either from the same player or a different one, are ignored.
Session-specific information (for example, connection counts) isn't relevant and, therefore, isn't available.
