# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.dataimpulse.com/proxies/parameters/session-interval.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
