### **粘性**
粘性代理基于端口。IP 地址在一段时间内绑定到特定端口。
粘性代理的轮换间隔可以从 1 到 120 分钟不等，平均持续时间为 30 分钟。
对于粘性连接，您可以使用从 **10000** 到 **20000**.
HTTP 粘性代理示例：
```
curl -x "http://login:password@gw.dataimpulse.com:10000" https://api.ipify.org/
```
SOCKS5 粘性代理示例：
```
curl -x "socks5://login:password@gw.dataimpulse.com:10000" https://api.ipify.org/
```
{% hint style="info" %}
如果未为粘性连接指定轮换间隔或将其设置为 "0"，默认间隔为 30 分钟。
{% endhint %}
