늘 불철주야 강의 찍으시느라 고생하시는 지식공유자님과 답글 달아주시는 선생님들의 노고에 항상 감사드리는 마음으로 질문 남깁니다.

상황

1, /servlet/members/new-form 에 들어가서 username, age를 입력해서 전송을 누른다.

2, 전송 버튼을 누르면 서블릿에서 member를 저장하고 그 결과로 /servlet/members/save의 html메시지를 메시지 바디에 담아서 응답한다.

질문1:

전송버튼을 누르면 /servlet/members/save url로 요청이 들어가는 게 맞는 건가요?

질문2:

위 코드를 2개로 쪼갰습니다. /servlet/members/new-form에서 데이터를 입력하고 전송을 눌렀을 때 부터의 콘솔창 입니다.

/servlet/members/new-form에서 보낸 요청 -> /servlet/members/new-form에 대한 응답

으로 끝나야 하는데 요청이 두 개 들어온 거는 왜 그런 건가요??
