Header - X-Device-Info header-x-device-info
Overview overview
The X-Device-Info request header contains the client information (device, connection and application) related to the actual streaming device and is used to determine platform-specific rules that MVPDs may enforce.

X-Device-Info header must contain a value formatted as described in the Directives section.Browsers browsers
For client applications running in a browser, the X-Device-Info header can be omitted as the browser will automatically send a minimal set of required information in the User-Agent header.
You can still use the X-Device-Info header to provide additional information about the device, connection, and application, in case your client application integrates a library or service that provides a device identification mechanism.
