REST API does not return JSON

[Kim Djernæs]

If I try to do an API request I always get a response in XML format - even if specifying the accepted format to be JSON.

Anyone that can explain this?

Thanks

Example:
curl -vv "http://10.2.0.13:8060/api/rest/fisheyeVersion" -H "Accept: application/json"
* Trying 10.2.0.13...
* Connected to 10.2.0.13 (10.2.0.13) port 8060 (#0)
> GET /api/rest/fisheyeVersion HTTP/1.1
> Host: 10.2.0.13:8060
> User-Agent: curl/7.47.0
> Accept: application/json
>
< HTTP/1.1 200 OK
