# Custom Sticky Sessions

> Residential Proxy Duration Specification

## Sticky Proxies

Decodo [residential proxies](https://decodo.com/proxies/residential-proxies) **sticky** sessions allow a proxy IP address to persist for up to **`24hours`** (**`1440`** minutes) before it's rotated to a different IP address.

<Note>
  The **default** sticky session time is `10minutes`.
</Note>

## Dashboard Proxy List Generation

To **generate** an endpoint list, navigate to the [**Dashboard → Proxy setup**](https://dashboard.decodo.com/residential-proxies/proxy-setup) section.

<Note>
  On the Proxy setup page, you can select between `1`, `10`, `30`, or `60`-minute sessions from a drop-down menu or specify a **custom duration** of up to `24hours`.
</Note>

## Custom Session Duration

You can use the `sessionduration` parameter together with the proxy **username** or a **whitelisted IP** to extend the length of a session up to **`24hours`** (**`1440`** minutes).

<Note>
  * The `sessionduration` parameter accepts any **integer** (minute) value between `1` and `1440`.
  * A `1440` minute duration is the longest possible proxy session.
</Note>

<Warning>
  ### Premature Rotation

  The longer the session you have, the more chances there are that **the IP will rotate before** your specified time due to the residential device at the end going offline.
</Warning>

## Multiple Concurrent Sticky Sessions

Adding the `session` variable to the proxy username or using a whitelisted IP will allow the proxy IP address to persist for multiple requests.

<Note>
  Different session parameter values are used to differentiate between active sessions and behave just like the different sticky proxy ports with our country endpoints. E.g.:

  * `session-1`
  * `session-2`
</Note>

## Examples

### Username:password

A `cURL` example using a **`90-minute`** long `sessionduration` parameter used with a proxy **username** and `session` **ID** to allow the IP address to persist for multiple requests:

<CodeGroup>
  ```shellscript cURL theme={null}
  curl -U "user-username-session-example1-sessionduration-90:password" -x "gate.decodo.com:7000" "https://ip.decodo.com/json"
  ```
</CodeGroup>

### Whitelisted IP

A `cURL` example using a **`90-minute`** long `sessionduration` parameter used with a **Whitelisted IP** and `session` **ID** to allow the IP address to persist for multiple requests:

<CodeGroup>
  ```shellscript cURL theme={null}
  curl -x "https://session-example1-sessionduration-90.gate.decodo.com:7000" "https://ip.decodo.com/json"
  ```
</CodeGroup>
