Mock exam question on encodeURL

[sid sree]

Which of the following is an example of URL rewriting by using encodeURL(String url)

1) http://localhost:8080/servlet/play;jsessionid=56
2) http://localhost:8080/servlet/play
3 ) http://localhost:8080/servlet/play?jsessionid=56
4 ) None of the above


The answer given is 1 and 2

Why is the third one wrong ?? Is it that encodeURL(..) is always going to use ; instead of ?

Thanks

the "?" denotes the start of the query string which has nothing to do with URL rewriting. Thaa is why it is not a correct answer
