Which of the following does the web server not do?

The web server's primary function is to host and manage web applications and content necessary for users to access web pages efficiently. It serves as a crucial intermediary between the internet and the application data, allowing users to retrieve and interact with information seamlessly.

When considering patient data management, the web server typically does not store patient data directly for faster retrieval. Instead, this data is usually managed by databases or backend systems that are optimized for data storage and retrieval. The web server interacts with these systems to fetch and deliver the requested information, but it does not maintain a local copy of patient data itself.

In contrast, the other options pertain to essential roles that a web server fulfills. It does house application files needed to build web pages, acts as an intermediary communicating between the user's request and the database storing information in Epic, and facilitates communication by serving interfaces through which users can interact with healthcare providers.
