Immediately Caching Dynamic Objects
Overview: Caching an object on first hit
The BIG-IP® system provides you with the ability to cache an object on the first cache hit, that is, the first time that an object is seen by the BIG-IP system. Typically, the BIG-IP system waits until the object is known to be popular, allowing a limited number of hits against the original content. Caching the object on first hit, however, causes the BIG-IP system to immediately cache the object, even if it is not popular. You only want to apply this setting for highly dynamic objects (for example, stock quotes provided by a stock ticker) that you want to cache for a limited time to offload the origin web server. If you use this setting on content that omits a Content-Length header, or if the object is an HTML, JavaScript (JS), or cascading style sheet (CSS) object, a significant degradation in performance can occur.
