지정된 HTTP 헤더를 요청에 설정할 수 있는지 여부를 테스트합니다.
public:
static bool IsRestricted(System::String ^ headerName);
public static bool IsRestricted (string headerName);
static member IsRestricted : string -> bool
Public Shared Function IsRestricted (headerName As String) As Boolean
매개 변수
- headerName

테스트할 헤더입니다.
반환
헤더가 제한되어 있으면 true이고, 그렇지 않으면 false입니다.
예외
headerName이 null 또는 Empty입니다.
headerName에 잘못된 문자가 들어 있는 경우
예제
다음 예에서는 속성을 확인 IsRestricted 하여 헤더 설정이 금지되어 있는지 확인합니다.
