# Session Interval

`sessttl` - Set the interval for IP rotation for sticky proxies, specifying the value in minutes.<br>

The Sticky Proxy configuration allows you to control the frequency of IP address rotation. You can set the interval for IP rotation by adding the `sessttl` parameter after the login, specifying the value in minutes.

\
**For example**, if you want the IP address to change every minute, you can use the following format: `sessttl.1`

If you want the IP address to change every hour, the value would be `sessttl.60`

{% hint style="info" %}
If the selected IP address becomes unavailable, the system will automatically replace it with another active IP address.
{% endhint %}

You can also specify both the country and the IP rotation frequency by adding parameters after the login.

**For example**, if you want to use an IP address from France with a rotation frequency of every hour, you can use the following format: `cr.fr;sessttl.60`

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

\
In this example, "cr.fr" represents France, and "sessttl.60" indicates a rotation frequency of 60 minutes.
