+# Load Data Using Stream Load
+
+The issue is that when the load client residents in a different network other than FE/BE's private network. FE's HTTP
+307 brings BE's private network address to the client who does not recognize and can't process the redirection.

+## How to Deploy Fe Proxy
+
+### Deploy Fe Proxy Using Helm
+
+If you install StarRocks with Helm, you can add the following configuration to the `values.yaml` file:
+
+For `kube-starrocks` Helm chart:
+
+```yaml
+starrocks:
+  starRocksFeProxySpec:
+    replicas: 1
+    # set the resolver for nginx server, default kube-dns.kube-system.svc.cluster.local
+    resolver: ""
+    limits:
+      cpu: 1
+      memory: 2Gi
+    requests:
+      cpu: 1
+      memory: 2Gi
+    service:
+      type: NodePort
+      ports:
+        - containerPort: 8080
+          name: http-port
+          nodePort: 30180
+          port: 8080
+```
+
+For `starrocks` Helm chart:
+
+```yaml
+starRocksFeProxySpec:
+  replicas: 1
+  # set the resolver for nginx server, default kube-dns.kube-system.svc.cluster.local
+  resolver: ""
+  limits:
+    cpu: 1
+    memory: 2Gi
+  requests:
+    cpu: 1
+    memory: 2Gi
+  service:
+    type: NodePort
+    ports:
+      - containerPort: 8080
+        name: http-port
+        nodePort: 30180
+        port: 8080
+```
+
+Please
+see https://github.com/StarRocks/starrocks-kubernetes-operator/blob/main/helm-charts/charts/kube-starrocks/values.yaml
+for more details about how to configure `starRocksFeProxySpec`.
+
+### Deploy Fe Proxy Using Helm
+
+If you install StarRocks with StarRocksCluster CR yaml, please see [deploy_a_starrocks_cluster_with_fe_proxy.md](
+../examples/starrocks/deploy_a_starrocks_cluster_with_fe_proxy.yaml)
