ASP.NET web.config 设置

<!--

        The system.webServer section is required for running ASP.NET AJAX under Internet

        Information Services 7.0.  It is not necessary for previous version of IIS.

-->

<system.webServer>

<defaultDocument>

            <files>

                <add value="UserLogin.aspx" />

            </files>

        </defaultDocument>

</system.webServer>

如果这个地方设了值,在IIS里设的就不管用了
