# Session Control

Session control types include rotating session and sticky session.

## **Rotating session:**

When configured:

• Dynamic IP Allocation: Assigns a new residential IP for every request

• Ideal for: High-anonymity use cases (e.g., anti-association analysis)

Configuration Rules:

● No session ID parameters required

● Enable Rotating Mode in the **Endpoint Generator** for immediate effect

{% endhint %}

## **Sticky session:**

The session ID parameter allows you to keep the same IP address to run multiple requests. To reuse the same IP multiple times, use `sessid` parameter after `username` with randomly created alphanumeric string, for example, `sessid-abc123`.

The `sesstime` parameter goes together with `sessid`, and allows you to prolong the session above 10 minutes or set a particular time for it.for example,`sessid-abc123-sesstime-10`The maximum session duration is **90 minutes**. The system will automatically rotate your IP once the preset time expires or if the IP becomes invalid.

{% hint style="danger" %}
*The sesstime does **not** guarantee completion of all requests before session expiration. Even if requests are still in progress, the session will terminate upon reaching the set time limit.*
{% endhint %}

The standard session time is 10 minutes or up to 90s of inactivity (no requests). After that, a new IP address is assigned automatically.&#x20;

> For example, your initial query with `sessid-abcde12345` assigned proxy IP address `1.1.1.1.` As long as you keep sending new requests with the same session ID and that IP address is online and available, the system will route your queries through `1.1.1.1.` If you stop sending requests for 60 seconds or the IP address is no longer online, the system will assign a new proxy IP. Your next query with `sessid-abcde12345` will be routed through a different IP address e.g. `1.1.1.2`.

Example represents a list of credentials that establish different sessions.

```
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
```

**Code example**

&#x20;`sessid-a123123-sesstime-10.`In this example We are using a US IP with `sessid` string and `sesstime` (10 minutes) in the username with the first request . All following requests will keep the same USA IP with further querieswe are adding&#x20;
