• Action Analytics
  : Collects run-time statistics on the basis of pre-defined criteria. When used with policies, the feature also provides you with the infrastructure for automatic, real-time traffic optimization.
• AppExpert Applications and Templates
  : Simplify configuration steps for the Citrix® NetScaler® appliance by using applications, application templates, Citrix Gateway applications, and entity templates.

• AppQoE
  : Application level Quality of Experience (AppQoE) integrates several existing policy-based security features of the Citrix ADC appliance into a single integrated feature that takes advantage of a new queuing mechanism, fair queuing.

• Pattern Sets
  : Allow string matching during the evaluation of a default syntax policy.
• Policies and Expressions
  : Rules that determine the operations that the Citrix ADC appliance must perform.
• Rate Limiting: Defines the maximum load for a given network entity or virtual entity on the Citrix ADC appliance.
• Responder
  : Bases responses on who sends the request, where it is sent from, and other criteria with security and system management implications.
• Rewrite
  : Rewrites information in the requests or responses handled by the Citrix ADC appliance.
• String Maps
  : Perform pattern matching in all Citrix ADC features that use the default policy syntax.
