We are going to use GET requests on URLs similar to these:
plus of course we will have to handle http authentication.
But maybe Wowza is in fact blessing the use of such URLs for that purpose same way it officially supports "Recording live streams using URL queries" (http://www.wowza.com/forums/content.php?123):
Sure, if it happened that the new EngineManager running on port 8088 was capable of digesting such URLs I'd love to use them. Engine manager is likely to live much longer.
