我们有一个带有 2 个 web.config 文件的 Web 应用程序。我在 ASP.NET 页面中使用 telerik:RadScriptManager 控件。该控件需要访问其 ScriptReferences 的 Web 资源文件 (WebResource.axd)。我认为这个 .axd 文件包含 Telerik 控件的 JavaScript 文件。我们所有的 Rad 控件都是在名为“admin”的单独 Web 应用程序 (.csproj) 项目中实现的。根 Web 应用程序项目 (.csproj) 有一个名为“admin”的文件夹，其中包含所有管理项目文件，包括管理 web.config。我在这里遇到问题的页面也存在于管理项目中。我认为它试图访问根文件夹中的 .axd 文件，而不是“/admin”文件夹。 （在更改 HTTP 处理程序的路径后，问题底部出现另一个错误）。如何使应用程序读取 ~/admin/Telerik.Web.UI.WebResource.axd 中的 WebResource.axd 文件而不是 ~/Telerik.Web.UI.WebResource.axd ？我猜测这 3 个 JavaScript 错误是由于此资源问题而导致的，因为当我显式导航到管理文件夹 URL 中的资源时，我可以看到 ASP.NET AJAX Control Toolkit JavaScript 代码。

我尝试将管理项目 web.config WebResource HTTP 处理程序的路径更改为“/admin/...”，但随后出现以下新错误。
<add verb="*" path="/admin/Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" validate="false" />
新错误：
