What is the recommended practice for pages with controls that have dynamic behavior?

The recommended practice for pages with controls that exhibit dynamic behavior is to keep OutputCache enabled while relying on client-side web service calls. This approach allows the server to deliver a cached version of the page to the client quickly while maintaining the ability to update specific dynamic elements on the page without needing to refresh the entire content.

By leveraging client-side web service calls, you can fetch and display up-to-date information asynchronously, enhancing the user experience without compromising performance. This method effectively balances the advantages of caching—such as reduced server load and faster response times—while still accommodating the need for dynamic features that reflect real-time data or user interactions.

The other options present challenges that could lead to inefficiencies or a poor user experience. Disabling OutputCache may result in increased server load and slower response times since every request would be processed without caching. Relying solely on server-side rendering can limit interactivity and responsiveness. Caching output for all user types disregards the need for personalized or user-specific content, which is often critical for web applications that cater to diverse audiences.
