带有回发的C#asp.net小部件默认登录，即使web.config不包括它.解决方法

我有一个用c#、asp.net编写的输入小部件"subscribeContact.aspx"。它被排除在"web.config"中的条目的授权之外。它默认显示登录页面。如果屏幕被刷新（例如F5），则无需登录即可显示小部件。
例程"WebinarDisplay.aspx"也包含回发函数，但不显示相同的行为。
web.config条目：
<location path="~/subscribeContact.aspx">
<system.web>
<authorization>
<allow users="?"/>
<allow users="*"/>
</authorization>
</system.web>
</location>
<location path="~/WebinarDisplay.aspx">
<system.web>
<authorization>
<allow users="?"/>
<allow users="*"/>
</authorization>
</system.web>
</location>

背后的代码是：

using System.Data;
namespace SchedulerServices
{
public partial class subscribeContact : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void submitButton_onClick(object sender, EventArgs e)
{
// test that fields are filled in
string xrefID = Request.QueryString["XR"];
bool sendBack = false;
firstNameLabel.ForeColor = System.Drawing.Color.Black;
if (string.IsNullOrEmpty(firstNameBox.Text.ToString()))
{
firstNameLabel.ForeColor = System.Drawing.Color.Red;
firstNameBox.Focus();
sendBack = true;
}
lastNameLabel.ForeColor = System.Drawing.Color.Black;
if (string.IsNullOrEmpty(lastNameBox.Text.ToString()))
{
lastNameLabel.ForeColor = System.Drawing.Color.Red;
lastNameBox.Focus();
sendBack = true;
}
emailLabel.ForeColor = System.Drawing.Color.Black;
if (string.IsNullOrEmpty(emailAddressBox.Text.ToString()))
{
emailLabel.ForeColor = System.Drawing.Color.Red;
emailAddressBox.Focus();
sendBack = true;
}
phoneNumberLabel.ForeColor = System.Drawing.Color.Black;

if (sendBack)
{

selectedFieldsRequired.Visible = true;
return;

// get the account ID and User ID

}
我被这件事难住了。其他独立页面工作起来没有问题，包括使用非排除区域中存在的代码。一旦页面加载，它就会正常工作。
问题是，无论web.config排除在外，回发都将执行login.aspx。
答案在于修改login.aspx.cs文件以在Page_Load部分包含以下代码：
protected void Page_Load(object sender, EventArgs e)
{
string returnURL = Request.QueryString["ReturnUrl"];
if (!string.IsNullOrEmpty(returnURL))
{
// Test for the exclusion
if (returnURL.Length > 7)
{
if (returnURL.Substring(1, 7) == "Webinar") // or whatever you want to continue on to processing
{
Response.Redirect(returnURL);
}
if (returnURL.Substring(1, 9) == "subscribe") // or whatever you want to continue on to processing
{
Response.Redirect(returnURL);
}
}
if (System.Web.HttpContext.Current.User != null && System.Web.HttpContext.Current.User.Identity.IsAuthenticated)
{
Response.Redirect(returnURL); // this exists to allow users to re-log in if the session has not timed out
}
}
RegisterHyperLink.NavigateUrl = "Register.aspx?ReturnUrl=" + HttpUtility.UrlEncode(Request.QueryString["ReturnUrl"]); // use this if you want the person directed to a registration page
ResendEmailHyperLink.NavigateUrl = "Resend.aspx?ReturnUrl=" + HttpUtility.UrlEncode(Request.QueryString["ReturnUrl"]); // use this if you want the person to have the registration email resent to them
ResetHyperLink.NavigateUrl = "ResetPassword.aspx?ReturnUrl=" + HttpUtility.UrlEncode(Request.QueryString["ReturnUrl"]); // use this to allow the user to reset their password
}
这现在起作用了。因此，解决方法是对Login.asp.cs（或您的登录页面）进行编码，以专门重定向到ReturnURL中的值。我在跟踪流程时重新发现了我的解决方法，并看到了我4年多前创建的工作。
我希望这能帮助其他人了解如何使用直接的C#、ASP.NET代码编写小部件，而不必使用JSON、JQUERY或MVC 进行更奇特的解决方案
