Advanced Caching Topics

Adequately covering the breadth of caching and all advanced topics would require a dedicated book on the subject, but we did want to draw your attention to two items of importance.

First, while all of our examples have focused on caching using configuration options, it is also possible to have your developers write code for dynamic cache “hooks” that can make caching, cache ID, and invalidation decisions on-the-fly. For example, certain entries may only be cached at certain times of the day or only after a certain number of repeated 'hits' and perhaps invalidated more often as resources become scarcer. This is covered in more detail in the WAS5 JavaDoc at http://publib7b.boulder.ibm.com/wasinfo1/en/info/ae/javadoc/ae/index.html ...
