Configure the Offline Viewer security settings - Author-it On-Premises

By default, Offline Viewer has security settings that restrict what it opens, and the resources it will load. These features can be configured or turned off in environments that don't require them, so that Offline Viewer is more convenient to use.

1. Find the OfflineViewer.config file, or create it.

   The file should be in the same directory as the Offline Viewer application.

2. Open OfflineViewer.config in a text editor.

3. Configure the disableExternalResources setting.

   This setting determines if Offline Viewer loads external resources such as pages, links, and images.

   • Set the value to true to disable external resources (default value if omitted).

   • Set the value to false to allow external resources.

4. Configure the verificationType setting

   This setting determines what checksum verification Offline Viewer performs before opening a .ofln file. Setting this value to Skip can be useful for organizations that can't, or don't need to, create a checksum file for .ofln files.

   • Set the value to Full to perform a full check on modified site contents (default value if omitted).

   • Set the value to Quick to perform a check on modified file sizes only.

   • Set the value to Skip to skip modification checks.

5. Save the changes to the OfflineViewer.config file.

   Ensure the file is saved in the same directory as the Offline Viewer application.

6. Ensure the OfflineViewer.config file can't be opened or edited by unauthorized users.
