# 会话控制

会话控制类型包含轮换会话和粘性会话两种

### **轮转会话**

当会话类型设为 **轮转会话** 时：

**动态IP分配**：每次请求自动分配**全新住宅IP**

**适用场景**：高匿名性业务需求

**配置规则**：

* 无需拼接会话标识参数
* 在端点生成器中启用 **轮转模式** 即可实时生效

{% endhint %}

### **粘性会话**

粘性会话允许保留单个 IP 地址，以便发起多个请求。要多次重复使用同一个 IP 地址，选择以下任一方式：

* **端点生成器配置**

▸ 切换会话模式为 黏性会话

▸ 设定持续时长（单位：分钟）

* **参数化配置**

在用户名后拼接：**`sessid-[自定义会话ID]+sesstime-[持续时间]`**

▸ 会话ID：字母数字组合（如abc123）

▸ 持续时间：整数分钟值（如10）

例如设定黏性模式持续时间为10分钟：`sessid-abc123-sesstime-10`

新的 IP 地址。标准会话时间为 10 分钟或不超过 60 秒的不活动时间（无请求）之后，将自动分配一个新的 IP 地址。

> 例如您使用 `sessid-a123123+sesstime-10` 被分配至代理 IP `1.1.1.1` 后，只要持续使用该会话参数发送请求且代理节点保持可用状态，您的请求将始终通过 `1.1.1.1` 进行传输。当会话时间超过预设的 10 分钟时，下一个使用 `sessid-a123123+sesstime-10` 的请求将自动分配新代理 IP，例如 `1.1.1.2`。

您也可以设定多条不同的会话代理地址，比如：

```
user-USERNAME-sessid-a234234-sesstime-15:PASSWORD
user-USERNAME-sessid-a345345-sesstime-30:PASSWORD
user-USERNAME-sessid-a456456-sesstime-45:PASSWORD
user-USERNAME-sessid-a567567-sesstime-90:PASSWORD
```

**代码示例：**

`sessid-a123123-sesstime-10`在此示例中，演示了如何通过包含`sessid`字符串和`sesstime`（10分钟）参数的美国IP进行首次请求。在10分钟会话有效期内，所有后续查询将继续使用该美国IP地址。
