Which type of content request does the Dispatcher primarily handle?

The Dispatcher primarily handles un-cached requests, which is crucial for managing dynamic content that needs to be pulled from a backend system or a database in real-time. This type of request occurs when a user or a system asks for data that has not been pre-processed and stored in the cache.

When dealing with un-cached requests, the Dispatcher ensures that the request is routed to the appropriate resource, often involving processing to produce the most current information. This is particularly important in scenarios where content is frequently updated or specific to individual users, which is not suitable for caching due to its dynamic nature.

In contrast, cached requests are typically served from the storage of previously retrieved and processed content, allowing for faster response times, but this is not the primary focus of the Dispatcher. Content uploads pertain to the instances where new information is being added to the system, and while the Dispatcher may play a role, it is not its main function. User login requests also vary in their handling and often involve authentication processes that are outside the Dispatcher’s primary responsibilities related to content management. Thus, focusing on un-cached requests highlights the Dispatcher's key role in ensuring that users receive the most up-to-date and relevant content.
