The advanced questions below may require you to dig into the HTTP specification [RFC 7231] or other online documents: Give the default connection timeout for the given server. Should the timeout value be short or long? Give reasons for your choice of answer. Is the connection dropped or kept open after the timeout? Can the connection be extended even after a timeout? Explain briefly. What are the maximum number of requests and responses the server has allowed? What happens when the maximum number of requests and responses are sent? What is the ETag in the success response message sent? State its significance. Will the ETag change if the resource content at this particular resource location changes?
