What is required to process information sent from a Web form to a Web server?

To process information sent from a Web form to a Web server, a Web server application is essential. This application acts as the intermediary between the user's input (submitted via the Web form) and the server's response. When a user fills out a form on a website and submits it, the browser sends this data to the Web server using HTTP. The Web server application receives this data, processes it according to predefined logic, and then decides how to respond—whether that's storing the data, sending a confirmation response back to the user, or redirecting the user to another page.

The other options, while related to the process, do not fulfill the specific requirement of handling the data once it's received. For instance, a Web browser is necessary for the user to interact with the Web form but does not actually process the data on the server. A Web form validator is designed to check user input for errors before submission, ensuring that only valid data is sent to the server, but it does not process the information itself. Similarly, a database connection is important for storing or retrieving data after the server has processed it, but the mere connection to a database does not handle the form data processing directly. Hence, the Web server application is the critical component required for this
