<!-- 동적 디버깅 컴파일
ASPX 디버깅을 사용하려면 compilation debug="true"로 설정합니다. 이렇게 하지 않고
해당 값을 false로 설정하면 이 응용 프로그램의 런타임 성능이 향상됩니다.
컴파일된 페이지에 디버깅 기호(.pdb 정보)를 삽입하려면 compilation debug="true"로 설정합니다.
이렇게 하면 파일 크기가 커져서 실행 속도가 느려지므로
디버깅하는 경우에만 이 값을 true로 설정하고
디버깅하는 경우 외에는 모두 false로 설정합니다. 자세한 내용은 ASP.NET 파일 디버깅에 관한
설명서를 참조하십시오.
