+## 原理图 (Caddy)：
+Xray client <--- gRPC(TLS) ---> Caddy2 <--- gRPC(cleartext) ---> Xray server
+
+## Nginx:
+
+同时，您也可以选择使用 Nginx。示例配置片段如下（来自 @xiaoQzhuren）：
+```conf
+# 填写你的 ServiceName
+location / {
+    if ($request_method != "POST") {
+        return 404;
+    }
+    client_max_body_size 0;
+    grpc_read_timeout 1071906480m;
+    grpc_pass grpc://127.0.0.1:2002;
+}
