Content-Security-Policy HTTP Header missing on splunk web request

[sudha_krish]

The Content-Security-Policy (CSP) HTTP header is missing on port 8000.
I do not see the Content-Security-Policy in the Splunk Web response headers.
How can I enable and configure a Content Security Policy for the Splunk Web UI?
