Description (partial)

When HTTP Response Header Content-Security-Policy value default-src 'self' is configured in IIS, the TMS web gui fails to load completely.

This response header is needed to enhance web server security to prevent Cross Site Scripting (XSS) and data injection attacks.

If the Response Header is set to  Content-Security-Policy1 value default-src 'self', the page will load properly.

This is a requirement for customer's security policies.
