What is the primary function of the Dispatcher in Adobe Experience Manager?

The primary function of the Dispatcher in Adobe Experience Manager (AEM) is to cache responses from publish instances. By caching content, the Dispatcher plays a crucial role in improving website performance and reducing the load on the publish instances by serving cached content quickly to users. This process minimizes the need to repeatedly access the backend repository for every incoming request, which can lead to performance bottlenecks. Additionally, caching helps in enhancing scalability, allowing more users to access the site simultaneously without degrading performance.

While the Dispatcher does contribute to optimizing server performance by reducing resource consumption, its main and most critical role focuses specifically on caching content. This functionality is vital for delivering a smooth user experience, particularly on high-traffic websites.
