When a server receives a GET request method, how does it know where to retrieve the requested information?

The correct answer is that the GET request provides the URL, which is fundamental to how HTTP requests work. When a client, such as a web browser, sends a GET request to a server, it includes a specific URL in the request. This URL contains the necessary information about the resource being requested, including the protocol (e.g., HTTP or HTTPS), the domain name (which identifies the server), and the path (which specifies the location of the resource on the server).

Upon receiving the GET request, the server parses the URL to determine where to find the requested resource. This process involves interpreting the domain to know which server is being addressed and the path to locate the specific file or data. The GET method is one of the most common types of HTTP methods used for retrieving data, and it relies entirely on the URL provided in the request to identify the location of the resource the client wants to access.

Other options do not accurately describe how the server retrieves information. Relying on previous requests to guess the required resource would not be effective or reliable, as each request could be for a different resource. Hard-coded paths in the server would limit its flexibility and usability, as servers are expected to handle a variety of requests dynamically based on the unique URLs
