This configuration variable allows the server administrator to specify a path which limits the File action, External (command line) actions, and attachments to Mail actions. The value of this configuration variable is prepended to the path specified in the File, External, or Mail action.
For more information, see Chapter 17 and Chapter 19 of the User's Guide, which give details on the External action and the File action, respectively.
This configuration variable can be used to set security on file reads, file writes, file deletes, mail attachments, and external actions that invoke the command line. Having the absolutePathPrefix set on a system-wide or application-specific basis means that system users or application users cannot access files in directories other than those under a certain directory.
