### 代理转发请求头如何工作 { #how-proxy-forwarded-headers-work }

下面是一个可视化图示，展示了**代理**如何在客户端与**应用服务器**之间添加转发请求头：

    Note over Proxy: Proxy adds forwarded headers

  - [alpha] Creating a `Federated Ingress` is as simple as submitting
    an `Ingress` creation request to the Federation API Server. The
    Federation control system then creates and maintains a single
    global virtual IP to load balance incoming HTTP(S) traffic across
    some or all the registered clusters, across all regions. Google's
    GCE L7 LoadBalancer is the first supported implementation, and
	is available in this release.

- Fixed an issue in the Windows kube-proxy (winkernel) where IPv4 and IPv6 Service load balancers could be incorrectly shared, causing broken dual-stack Service behavior. The kube-proxy now tracks load balancers per IP family, enabling correct support for PreferDualStack and RequireDualStack Services on Windows nodes.
