Which of the following are standard techniques for providing a sense of state" to HTTP?
Select 3.

1.Kookies
2.URL rewriting
3.SSL sessions
4.username-password
5.Http is already a stateful protocol.

answers given are: 1,2,3.

But my doubt is that SSL sessions are used with HTTPS protocol then how can option 3 be correct?

Thanks

HTTPS is based on HTTP protocol(HTTPS = Secure HTTP).
HTTPS uses SSL and provides a builtin mechanism to handle session tracking.
So the answer is correct.

To expand on what Antonio said, HTTPS is HTTP, just over a secure communications channel. In that sense, it adds something to HTTP that establishes state. The same is true for cookies and URL rewriting - they don't alter HTTP, they use it to establish state. Neither is part of HTTP as described in the RFC.
