Section Referrer Check defines what commands will require validation of
referring page and what domains will be accepted as valid referrers.
It has a variable Referrer that contains a comma-separated list of servers (domains) that will be accepted by WBSP engine as valid hosts for referring pages.
If this variable does not exist (or it is empty) then WBSP engine will not try to validate referrer. If you want to allow referring page to be located only on same server as WBSP file set this variable to $self$.
The main change from previous versions is that this section is part of the WBSP file while in previous versions it was part of WhizBase.ssc server-side configuration file.
