摘要： A method, system, and computer program product for caching dynamically generated content (including, but not limited to, dynamically generated Web pages), as well as determining when the cached content should be invalidated or purged. Rather than caching the generated datastream (i.e. the end result of the computations used in the dynamic generation process) as in the prior art, the interim results of computations (such as a generated bean instance or object, where the interim results may be stored using properties and methods) are cached according to the present invention. The input properties used to generate the bean or object, along with the input property values, are used to distinguish among cached instances and thereby identify when a cached instance may be used to respond to a subsequent request for the same content. Re-execution of the business logic of the bean or object may then be avoided, using the cached bean's or object's output properties to generate the content response. Application-specific, developer-defined criteria may be used in the cache invalidation determination.
摘要翻译：用于缓存动态生成的内容（包括但不限于动态生成的网页）的方法，系统和计算机程序产品，以及确定缓存的内容何时应该被无效或被清除。不像在现有技术中缓存生成的数据流（即动态生成过程中使用的计算的最终结果），而是计算的中期结果（例如生成的bean实例或对象，其中可以使用属性和方法）根据本发明被缓存。用于生成bean或对象的输入属性以及输入属性值用于区分缓存的实例，从而识别何时可以使用缓存的实例来响应相同内容的后续请求。然后可以避免重新执行bean或对象的业务逻辑，使用缓存的bean或对象的输出属性来生成内容响应。特定于应用程序的开发人员定义的标准可用于缓存无效确定。
