For example, you have group1 that is bound with a session policy configured with the home page www.homepage1.com. Group2 is bound with a session policy configured with home page www.homepage2.com. When these policies are bound to respective groups without a priority number or with a same priority number, the home page that appears to users who belong to both the groups depends on which policy is processed first. By setting a lower priority number, which gives higher precedence, for the session policy with home page www.homepage1.com, you can ensure that users who belong to both the groups receive the home page www.homepage1.com.
