如何在 Signout.aspx 上设置 SharePoint cookie 的到期时间

如何解决如何在 Signout.aspx 上设置 SharePoint cookie 的到期时间

我想为 Sharepoint 的身份验证 Cookie 设置到期日期，我已经提到了微软页面 (https://docs.microsoft.com/en-us/previous-versions/aspnet/ms178195(v=vs.100)?redirectedfrom=MSDN#to-assign-a-past-expiration-date-on-a-cookie)

根据他们的建议，我已将以下代码添加到 Signout.aspx，但似乎不起作用。

<asp:content contentplaceholderid="PlaceHolderAdditionalPageHead" runat="server">
<SharePoint:ScriptBlock runat="server">
function _spBodyOnLoad()
{
If (Not Request.Cookies("EdgeAccessCookie") Is nothing) Then
    Dim myCookie As HttpCookie
    myCookie = New HttpCookie("EdgeAccessCookie")
    myCookie.Expires = DateTime.Now.AddDays(-1D)
    Response.Cookies.set(myCookie)
End If
    window.close();
}
</SharePoint:ScriptBlock>
</asp:Content>
