Citrix NetScaler Policy Configuration and Reference Guide
Creating or Modifying an Advanced Policy
All advanced policies have some common elements. Creating an advanced policy
consists, at minimum, of naming the policy and configuring a rule. The policy
configuration tools for the various features have areas of overlap, but also
differences. For the details of configuring a policy for a particular feature,
including associating an action with the policy, see the documentation for the
feature.

configuration tools for the various features have areas of overlap, but also
differences. For the details of configuring a policy for a particular feature,
including associating an action with the policy, see the documentation for the
feature.
To create a policy, begin by determining the purpose of the policy. For example,
you may want to define a policy that identifies HTTP requests for image files, or
client requests that contain an SSL certificate. In addition to knowing the type of
information that you want the policy to work with, you need to know the format
of the data that the policy is analyzing.

of the data that the policy is analyzing.
Next, determine whether the policy is globally applicable, or if it pertains to a
particular virtual server. Also consider the effect that the order in which your
policies are evaluated (which will be determined by how you bind the policies)
will have on the policy that you are about to configure.
