To answer this question, you need to understand the different cache strategies available in web development. Let's go through each option to understand why it is correct or incorrect:
Option A) Use the output cache - This option is correct because the output cache stores the generated output of a web page or user control, which can significantly improve performance by serving the cached content instead of re-executing the entire page or control. This strategy is especially useful for static or infrequently changing content.
Option B) Use the cache object - This option is incorrect. The cache object is used to store data in memory for a specific duration or until it is removed from the cache. While it can improve performance by reducing the need to retrieve data from a database or other external sources, it is not the best strategy for this scenario as it doesn't specifically address the retrieval of historical books information.
Option C) Use the ASP.NET central cache - This option is incorrect. The ASP.NET central cache, also known as the System.Web.Caching.Cache class, is a shared cache that can be accessed by multiple applications running on the same server. While it can provide some performance benefits by allowing multiple applications to share cached data, it is not the best strategy for this scenario as it doesn't specifically address the retrieval of historical books information.
Option D) Use the client cache - This option is incorrect. The client cache refers to storing data on the client-side, typically in the user's browser. While it can improve performance by reducing the need to retrieve data from the server, it is not the best strategy for this scenario as it doesn't specifically address the retrieval of historical books information.
The correct answer is A) Use the output cache. This option is correct because it specifically addresses the caching of generated output, which can greatly improve performance by serving the cached content instead of re-executing the entire page or control.
