HTTP Responses

An HTTP response contains a result code, header fields, and a body.

The HTTP protocol expects the result code and all header fields to be returned before any body content.

Some commonly used status codes include:

• 404 - indicates that the requested resource is not available.
• 401 - indicates that the request requires HTTP authentication.
• 500 - indicates an error inside the HTTP server which prevented it from fulfilling the request.
• 503 - indicates that the HTTP server is temporarily overloaded, and unable to handle the request.
