我正在尝试了解 asp.net 成员身份的密码恢复技术。
这是我的 web.config 文件：
<?xml version="1.0"?>

web admin tool to configure settings for your application. Use
the Website->Asp.Net Configuration option in Visual Studio.

<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.

<compilation debug="true"/>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx">
</forms>
</authentication>
<authorization>
<allow users="*"/>
</authorization>
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->

但我从 IIS 收到此错误：
