Table 5-16 Optimization Action List Configuration Options

Field Description

Action List Name Enter a unique name for the optimization action list. Valid entries are unquoted text strings with a

maximum of 64 alphanumeric characters.

Enable Delta Delta optimization dynamically updates client browser caches directly with content differences, or

deltas, resulting in faster page downloads.

Check this check box to enable delta optimization for the specified URLs.

Clear this check box to disable delta optimization for the specified URLs.

Note The ACE restricts you from enabling delta optimization if you have previously specified either

Cache Dynamic or Dynamic Entity Tag.

Enable AppScope AppScope runs on the Management Console of the optional Cisco AVS 3180A Management Station and

measures end-to-end application performance.

Check this check box to enable AppScope performance monitoring for use with the ACE appliance.

Clear this check box to disable AppScope performance monitoring for use with the ACE appliance.

Flash Forward The FlashForward feature reduces bandwidth usage and accelerates embedded object downloading by

combining local object storage with dynamic renaming of embedded objects, thereby enforcing object

freshness within the parent HTML page.

Specify how the ACE appliance is to implement FlashForward:

• N/A—Indicates that this feature is not enabled.

• Flash Forward—Indicates that FlashForward is to be enabled for the specified URLs and that

embedded objects are to be transformed.

• Flash Forward Object—Indicates that FlashForward static caching is to be enabled for the objects

that the corresponding URLs refer to, such as Cascading Style Sheets (CSS), JPEG, and GIF files.

Cache Dynamic Check this check box to enable Adaptive Dynamic Caching for the specified URLs even if the expiration

settings in the response indicate that the content is dynamic. The expiration of cache objects is

controlled by the cache expiration settings based on time or server load.

Clear this check box to disable this feature.

Note The ACE restricts you from enabling Cache Dynamic if you have previously specified either

Enable Delta or Dynamic Entity Tag.

Cache Forward Check this check box to enables the cache forward feature for the corresponding URLs. Cache forward

allows the ACE to serve the object from its cache (static or dynamic) even when the object has expired

if the maximum cache TTL time period has not yet expired (set by specifying the Cache Time-To-Live

Duration (%): field in an Optimization parameter map). At the same time, the ACE sends an

asynchronous request to the origin server to refresh its cache of the object.

Clear this check box to disable this feature.
