You want to exclude one or more URLs from inspection/scan in Symantec Data Loss Prevention (DLP).
This can be done in multiple ways.
Frequently we are presented with exclusions not working when attempting to use <-abc.com/mydirectory>
Subdirectory functionality is not allowed and will not work.
You cannot add subdirectories to the domain, you can only exclude the domain itself.
Feature requests have been provided for this functionality and were denied as the computational power required to provide this functionality is too great to be practical at this time.
