HttpCapabilitiesBase.RequiresUniqueFilePathSuffix 屬性

public:
 virtual property bool RequiresUniqueFilePathSuffix { bool get(); };

public virtual bool RequiresUniqueFilePathSuffix { get; }

member this.RequiresUniqueFilePathSuffix : bool

Public Overridable ReadOnly Property RequiresUniqueFilePathSuffix As Boolean

屬性值

true如果瀏覽器需要唯一的表單動作 URL;否則，。 false 預設值為 false。

範例

以下程式碼範例說明如何判斷瀏覽器是否需要唯一的表單動作 URL。

備註

自我參照的 HTML <form> 元素是指其 action 屬性指定自身 URL 的元素。 若 true，自我參照表單不會回傳正確結果。 這是因為瀏覽器或中介閘道器的快取所致。 為了修正此問題，伺服器控制介面卡會在自參照表單的表單動作 URL 值上附加預設查詢字串（__ufps=``uniquefilepathsuffix）。
