允许未经身份验证的用户使用ASP.Net表单身份验证访问特定页面

我使用ASP.Net表单验证。我的Web.config看起来像这样。

<authentication mode="Forms">
      <forms loginUrl="login.aspx"/>
    </authentication>
    <authorization>
      <deny users="?" />
    </authorization>

因此，目前每个aspx页面都需要身份验证。

我想允许甚至未经身份验证的用户访问名为special.aspx的特定页面。
我如何做到这一点？

解决方法

看看 MS Support的例子

<configuration>
    <system.web>
        <authentication mode="Forms" >
            <forms loginUrl="login.aspx" name=".ASPNETAUTH" protection="None" path="/" timeout="20" >
            </forms>
        </authentication>
<!-- This section denies access to all files in this 
application except for those that you have not explicitly 
specified by using another setting. -->
        <authorization>
            <deny users="?" /> 
        </authorization>
    </system.web>
<!-- This section gives the unauthenticated 
user access to the ThePageThatUnauthenticatedUsersCanVisit.aspx 
page only. It is located in the same folder 
as this configuration file. -->
        <location path="ThePageThatUnauthenticatedUsersCanVisit.aspx">
        <system.web>
        <authorization>
            <allow users ="*" />
        </authorization>
        </system.web>
        </location>
<!-- This section gives the unauthenticated 
user access to all of the files that are stored 
in the TheDirectoryThatUnauthenticatedUsersCanVisit folder.  -->
        <location path="TheDirectoryThatUnauthenticatedUsersCanVisit">
        <system.web>
        <authorization>
            <allow users ="*" />
        </authorization>
        </system.web>
        </location>
</configuration>
