Block insecure content on specified sites

Creates a list of URL patterns to specify sites that aren't allowed to display blockable (that is, active) mixed content (that is, HTTP content on HTTPS sites) and for which optionally blockable mixed content upgrades are disabled. If you don't configure this policy, blockable mixed content is blocked, and optionally blockable mixed content is upgraded. However, users are allowed to set exceptions to allow insecure mixed content for specific sites. For detailed information about valid URL patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. Wildcards (*) are allowed. Example value: https://www.example.com [*.]example.edu
