我们有一个网站，其中前端是托管在 Azure Blob 存储中的 SPA，后端托管在 Azure 应用服务中。该站点的前面将是 Azure Front Door。我正在尝试将请求路由到正确的后端。
应用服务中托管的站点中的所有终结点都具有 /backend/* 格式。
在前端，我们在根目录中有一些文件，/index.html 和一些其他文件，如 favoicon.ico，然后是 /assets 文件夹中的一些文件。这些唯一的共同点是它们在文件名中有一个句点。
SPA 具有不对应于任何物理文件的动态 url，例如 /login。
我想要 Front Door 中的以下路由，但我在为/*.*模式创建规则时遇到问题，即将看起来像文件的所有内容路由到 blob 存储而无需重写 url。

还有其他方法可以完成这项工作吗？
