# 会话间隔

`sessttl` - 为粘性代理设置 IP 轮换的间隔，值以分钟为单位。<br>

粘性代理配置允许您控制 IP 地址轮换的频率。您可以通过在登录后添加 `sessttl` 参数来设置 IP 轮换的间隔，值以分钟为单位。

\
**例如**，如果您希望 IP 地址每分钟更换一次，可以使用以下格式： `sessttl.1`

如果您希望 IP 地址每小时更换一次，值将为 `sessttl.60`

{% hint style="info" %}
如果所选的 IP 地址不可用，系统将自动用另一个可用的 IP 地址替换它。
{% endhint %}

您也可以通过在登录后添加参数同时指定国家和 IP 轮换频率。

**例如**，如果您想使用来自法国的 IP 地址并设置每小时轮换一次，可以使用以下格式： `cr.fr;sessttl.60`

```
curl -x "http://login__cr.fr;sessttl.60:password@gw.dataimpulse.com:10000" https://api.ipify.org/
```

\
在此示例中，"cr.fr" 代表法国，"sessttl.60" 表示 60 分钟的轮换频率。
