# Proxy Rotator - Optional

This service is optional, if you wish to use Proxy Rotator - contact your Account Manager to receive a domain.

Instead of connecting to individual IPs, we provide you with a single endpoint to your assigned proxy list. With every request, the endpoint fetches a different IP. Please see the example below to learn how to use the endpoint as a proxy.

{% hint style="info" %}
The [vm.oxylabs.io](http://vm.oxylabs.io) domain is an example only. Contact your Account Manager to get a domain forwarded to you.
{% endhint %}

{% hint style="success" %}
Proxy Rotator should be used only with port `60000`.
{% endhint %}

#### Code examples

```shell
curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location
```

curl_setopt($query, CURLOPT_PROXYUSERPWD, "username:password");

            return result;

### Session Control Using Proxy Rotator

It is possible to keep the same IP address with the Proxy Rotator. Firstly, you will need to know how many proxies your Proxy Rotator has. Then add the `--proxy-header "Proxy-Server: sXXX"` header to your request, where `sXXX` is the number of the proxy, for example, `s5` or `s2541`.

#### Code examples

{% tabs %}
{% tab title="cURL" %}

```shell
user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40
user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40
user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40
```

{% endtab %}

{% tab title="PHP" %}

```php
<?php
$query = curl_init('https://ip.oxylabs.io/location');
curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($query, CURLOPT_PROXY, 'http://vm.oxylabs.io:60000');
curl_setopt($query, CURLOPT_PROXYUSERPWD, "username:password");
curl_setopt($query, CURLOPT_PROXYHEADER, [
    "Proxy-Server: s10",
]);

$output = curl_exec($query);
curl_close($query);
if ($output) {
    echo $output;
}
```

{% endtab %}

{% tab title="Python" %}

```python
import requests


class ProxyAdapter(requests.adapters.HTTPAdapter):
    def proxy_headers(self, proxy):
        headers = super(ProxyAdapter, self).proxy_headers(proxy)
        headers['Proxy-Server'] = 's10'
        return headers


s = requests.Session()
s.proxies = {'http': 'http://username:password@vm.oxylabs.io:60000',
             'https': 'http://username:password@vm.oxylabs.io:60000'}
s.mount('http://', ProxyAdapter())
s.mount('https://', ProxyAdapter())
response = s.get('https://ip.oxylabs.io/location')
print(response.text)
```

{% endtab %}

{% tab title="C#" %}

```csharp
using System;
using System.Net;

class Example
{
    static void Main()
    {
        var client = new WebClient();
        client.Proxy = new WebProxy("http://vm.oxylabs.io:60000");
        client.Proxy.Credentials = new NetworkCredential("user1", "pass1");

        client.Headers.Add("Proxy-Server", "s10");

        Console.WriteLine(client.DownloadString("https://ip.oxylabs.io/location"));

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://developers.oxylabs.io/products/proxies/dedicated-datacenter-proxies/enterprise/proxy-rotator-optional.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.
