The Web Server is primarily responsible for handling incoming user requests in Appian. When a user interacts with an Appian application, such as accessing a site or submitting a form, the request is first directed to the Web Server. This component processes those requests and communicates with other server components to fulfill them, including routing traffic appropriately and serving static content.

The Web Server also plays a crucial role in managing user sessions and ensuring that requests are efficiently processed and directed to the appropriate resources. It handles the HTTP transactions that form the basis of web communication, acting as the first point of contact for users before their requests reach the application logic or database.

In contrast, while the Application Server does perform important back-end processing and runs the business logic of applications, it is not the initial point of entry for user requests. The Search Server is dedicated to indexing and searching data within Appian, and the Data Server focuses on managing data storage and retrieval. These components serve specialized functions that are essential for the overall performance and capability of an application but do not handle incoming user requests directly like the Web Server does.
