About Policy Bindings
A policy is associated with, or bound to, an entity that enables the policy to be 
invoked. For example, you can bind a policy to request-time evaluation that 
applies to all virtual servers. A collection of policies that are bound to a particular 
bind point constitutes a policy bank.
Following is an overview of different types of bind points for a policy:
Request time global. A policy can be available to all components in a feature at 
request time.
Response time global. A policy can be available to all components in a feature at 
response time.
Request time, virtual server-specific. A policy can be bound to request-time processing 
for a particular virtual server. For example, you can bind a request-time policy 
to a cache redirection virtual server to ensure that particular requests are 
forwarded to a load balancing virtual server for the cache, and other requests 
are sent to a load balancing virtual server for the origin. 
Response time, virtual server-specific. A policy can also be bound to response-time 
processing for a particular virtual server.
