Remarks
HttpMJpegServer works in terms of contexts. Each time a client connects a new context is created, identified by a
unique Id. When a client connects initially,
the OnAddContext event is raised to notify the application of a new guid. Immediately after that, OnInitialRequest
is raised, to communicate context, request
and response to the application. When a client disconnects, the OnRemoveContext event is raised.
