What information is included in an HTTP response "start line"?

• A. Status Code
• B. Request Method
• C. Response Headers
• D. Path to Resource

Answer: (A)

The start line of an HTTP response is a critical component that conveys essential information about the result of an HTTP request. Specifically, it consists of the protocol version being used, a status code, and a corresponding status message. The status code is a three-digit number that indicates the outcome of the request—whether it was successful, encountered client errors, or server errors. To elaborate, the status codes help clients (such as web browsers) understand what happened during the processing of their request. For example, a status code of 200 indicates success, while a code of 404 signifies that the requested resource could not be found. Thus, the inclusion of the status code in the start line is crucial for both functionality and user experience in web communications. The other options listed pertain to other aspects of HTTP communications. The request method, for instance, is part of the HTTP request line and not the response start line. Response headers and the path to the resource are also elements related to the broader HTTP response but do not fall under the definition of the start line itself; response headers follow the start line and provide additional metadata about the response.
