# Session Stickiness

### Establishing a session

The `sessionid` proxy header maintains the same IP address for a session up to 10 minutes, as long as the IP remains in the pool. If not, a new IP is assigned. To reuse an IP, use the same `sessionid` header with a unique identifier of 4 to 10 digits, e.g., `sessionid-42831931` . 

For session duration adjustments, contact us at <support@goproxies.com>.

### Credentials list of examples for different sessions

Examples below contain a list of credentials that establish a new unique session.

`customer-USERNAME-sessionid-7129391:PASSWORD`\
`customer-USERNAME-sessionid-8128311:PASSWORD`\
`customer-USERNAME-sessionid-1812819:PASSWORD`\
`customer-USERNAME-sessionid-289301:PASSWORD`\
`customer-USERNAME-sessionid-3916211:PASSWORD`<br>

### Understanding sessionid header

When using a session ID, such as `customer-USERNAME-sessionid-7129391:PASSWORD`, the proxy assigns you an IP address (e.g., 1.1.1.1), valid for 10 minutes. Any requests using the same `sessionid` will return the same IP. If there's no activity with the session ID for 10 minutes, you may be assigned a new IP (e.g., 1.1.1.2), or if the old IP is unavailable, it will be replaced as well.

### Request example

```bash
curl --proxytunnel --proxy "https://customer-USERNAME-sessionid-7182391:PASSWORD@proxy.goproxies.com:1080" https://ip.goproxies.com
```

{% endtab %}

{% tab title="JavaScript" %}

```javascript

const proxyAuth = encodeURIComponent(username) + ':' + encodeURIComponent(password);
const proxyUrl = `http://${proxyAuth}@proxy.goproxies.com:1080`;
const agent = new HttpsProxyAgent(proxyUrl);

(async () => {
  try {
    const res = await axios.get('https://ip.goproxies.com', { httpsAgent: agent, timeout: 10000 });
    console.log(res.status, res.data);
  } catch (err) {
