Go back to Question 8
True. See The Python Standard Library - 21.12. http.client - HTTP protocol client .
Go back to Question 7
False. If the port is empty or not given, port 80 (not port 8080) is assumed. See section 3.2.2 of w3.org - 3 Protocol Parameters .
Go back to Question 6
True.
Go back to Question 5
True. HTTP is a connectionless and as a result, HTTP is a stateless protocol. The server and client are aware of each other only during a current request.Afterwards, both of them forget about each other insofar as the protocol is concerned. Note however that browsers use various methods, such as cookies, tostore information about previous connections but that capability is not built into the HTTP protocol.
Go back to Question 4
True. Any type of data can be sent by HTTP as long as both the client and server know how to handle the data content.
Go back to Question 3
False. The HTTP client (typically a browser) initiates an HTTP request. After a request is made, the client disconnects from the server and waits for aresponse. The server processes the request and re-establish the connection withthe client to send response back.
Go back to Question 2
True. See tutorialspoint -- HTTP -- Quick Guide .
