This configuration is used to normalise and remove the trailing (last) forward slash from URLs so that links clicked to the same URL with or without a forward slash are counted as the same link (note that in some cases they may not be the same link).
This is enabled through the system configuration "Admin.System.Reports.Exclude Forward Slash From Links"
which can be enabled by your Account Manager or Vuture Support
Once enabled all reports that include links clicked statistics will treat a link with and without a forward slash as the same link.
