Hi,
Using Wowza 4.3.0, I’ve setup the HTTPStreamer CORS for HLS like this:
```auto
cupertinoUserHTTPHeaders
Access-Control-Allow-Origin: *|Access-Control-Allow-Methods: GET, POST, OPTIONS|Access-Control-Allow-Headers: Range
```
In “conf/Application.xml”, “conf/vod/Application.xml”, “conf/live/Application.xml” and “conf/Myapp/Application.xml”.
And it works if I access “playlist.m3u8” for example. But if I access “jwplayer.smil” it does not. The headers are not sent.
Any pointers?

Hi,
The cupertinoUserHTTPHeaders Property is specific to Apple HLS playback. If you’re using “jwplayer.smil” this is playback via RTMP protocol using the built-in HTTPProvider.

I recommend that you update to the latest version of Wowza Streaming Engine using the [Upgrade guide](https://www.wowza.com/docs/software-updates).
This will allow you to take advantage of the new CORS related configuration via Wowza Streaming Engine Manager as seen in the article below.
