In my application.xml <<HTTPStreamer> properties, I'm using the cupertinoPlaylistHostDomain property. This is working fine on wms2, but on wms3 on EC2, the m3u8 response is coming back with a relative location rather than the expected http://[value of cupertinoPlaylistHostDomain] . I've confirmed that my startup script is adding the proper value for cupertinoPlaylistHostDomain (the public IP of the instance).
Has something changed in WMS3?
*Edit - Just tested this on one of my dedicated WMS3 installations, results are the same as on EC2
