HttpWebRequest.ServicePoint プロパティ

要求に対して使用するサービス ポイントを取得します。

Public ReadOnly Property ServicePoint As ServicePoint
[C#]
public ServicePoint ServicePoint {get;}
[C++]
public: __property ServicePoint* get_ServicePoint();
[JScript]
public function get ServicePoint() : ServicePoint;

プロパティ値

インターネット リソースへのネットワーク接続を表す ServicePoint 。

解説

要求がリダイレクトされる場合、 ServicePoint.Address プロパティは、 HttpWebRequest.Address とは異なる場合があります。
