推荐答案

服务器会将 X-Cascade 标头设置为pass"以继续尝试其他路由.这允许嵌套/堆叠多个路由.

The server will set the X-Cascade header to "pass" to continue to try other routes. This allows for multiple routes to be nested/stacked.

这样做的一般目的是将请求传递给其他中间件来处理该请求，如果该特定处理程序不处理该请求.

The general purpose of this is to pass the request on to other middlewares to handle the request if that specific handler doesn't handle it.
