  Policies
Note
When you define multiple membership criteria, the client request must meet all criteria to match 
the policy.
Policy Order
The order in which policies are listed in a policy table determines the priority with which they are applied 
to web requests. Web requests are checked against policies beginning at the top of the table and ending 
at the first policy matched. Any policies below that point in the table are not processed. 
If no user-defined policy is matched against a web request, then the global policy for that policy type is 
applied. Global policies are always positioned last in Policy tables and cannot be re-ordered.
