I am a bit confused with HTTP lately. Some facts are that TCP can operate connection orientated or connectionless this I understand. TCP though is connection-oriented while UDP is connectionless which is used when the message itself can be fit into a single message.

Question:

If HTTP uses TCP, and TCP provides reliable conjnections for multiple message excahnge, and HTTP is said to be connectionless then how is this possible?

TCP is connection-oriented? So how is HTTP connectionless????
