Strategy allows you to export content from various locations. Certain locations are specified by a URL. For example, an attribute form may contain a URL that specifies the location of an image. The image is fetched during the exporting process and placed in the PDF output at the appropriate location.
As of Strategy 2020 Update 1, administrators can specify which URLs or URL paths are permitted when fetching content to be included in an export. This concept, where only certain URLs are permitted, is largely referred to as whitelisting.
Further information about this feature can be found in this documentation. After adding URLs in the Web administrator page described, the administrators may find that the setting is not retained.
Changes made to the project configuration or Intelligence Server configuration using an older version of Developer will overwrite the existing definition of the setting in the Web Administrator page. The older version of Developer will use the default setting because the setting was introduced with Strategy 2020 Update 1.
Upgrade Developer to match the same version as the Intelligence Server.
