ABSTRACT:
Dynamic Caching completely changes the caching model, making it possible to cache a much broader variety of content including highly dynamic web pages, query responses, and XML objects. This patented technology is completely unique to F5 and unavailable from any other vendor.
Dynamic Caching focuses on application logic and behavior, not just individual web objects. By understanding an application's high-level logic (what can and cannot be cached, what events cause invalidation, etc.), the WebAccelerator eliminates repeated processing of complex web requests. Dynamic Caching enables the WebAccelerator system to decide when to invalidate objects and how to identify reusable pieces of content.
Without WebAccelerator and Dynamic Caching, the existing caching solution has only the object expiration date as a guide. Dynamic Caching enables the cache to look at anything in an HTTP request—from URLs to cookies, query parameters and other headers--and produce "smart" invalidations and cache keys. Additionally, it enables the WebAccelerator system to decide when to invalidate objects and how to identify single pieces of content.
