List of URLs specifying which urls AutoOpenFileTypes will apply to. This policy has no impact on automatically open values set by users. If this policy is set, files will only automatically open by policy if the url is part of this set and the file type is listed in AutoOpenFileTypes. If either condition is false the download won't automatically open by policy. If this policy isn't set, all downloads where the file type is in AutoOpenFileTypes will automatically open. A URL pattern has to be formatted according to https://support.google.com/chrome/a?p=url_blocklist_filter_format. Example value: example.com https://ssl.server.com hosting.com/good_path https://server:8080/path .exact.hostname.com
