A VIPRION system provides you with the ability to cache objects either for a policy node in a cluster or on a single cluster member. Typically, caching objects in a cluster achieves optimum acceleration for large, static objects. Comparatively, caching objects on a single cluster member achieves optimum acceleration for small, dynamic objects.

1. On the Main tab, click Acceleration > Web Application > Policies. The Policies screen displays a list of existing acceleration policies.
2. Click the name of a user-defined acceleration policy.
3. Click a node in the Policy Tree.
4. From the Matching Rules menu, choose Acceleration Rules.
5. On the menu bar, click Responses Cached.
6. Optional: For the Object Min Size setting, clear the Use Profile Setting check box, and type the minimum object size (in bytes) to cache, overriding the Web Acceleration profile setting.
7. Optional: For the Object Max Size setting, clear the Use Profile Setting check box, and type the maximum object size (in bytes) to cache, overriding the Web Acceleration profile setting.
8. From the Content Coherency list, select a cache coherency setting.
