Kestrel Proxy

A server proxy is software installed on a computer on a network that allows you to make requests to other computers on your behalf. A server proxy is a kind of intermediary that ensures the secure exchange of data.

There are lots of ways to use them. For example, you can swap your real IP address location for an American one, thus getting the opportunity to watch Netflix at a bargain price. Or you can set up parsing traffic through a proxy to test the security of your web applications. Or you can create a proxy server on your local network that allows traffic through and blocks requests to certain sites.

To quickly scrape a large number of sites using Node.js, you can leverage asynchronous programming and utilize libraries like axios for making HTTP requests and cheerio for parsing HTML. Additionally, you may consider using the p-queue library to manage the concurrency and control the rate of requests. Here's a basic example to get you started

Install Required Packages:

npm install axios cheerio p-queue

Create a Scraper Script:

const axios = require('axios');
const cheerio = require('cheerio');
const PQueue = require('p-queue');

// List of sites to scrape
const sites = [
  'https://example1.com',
  'https://example2.com',
  // Add more URLs as needed
];

// Set the concurrency level (adjust as needed)
const concurrency = 5;

// Initialize a queue with concurrency control
const queue = new PQueue({ concurrency });

// Function to scrape a single site
async function scrapeSite(url) {
  try {
    const response = await axios.get(url);
    const $ = cheerio.load(response.data);

    // Use Cheerio to parse and extract data
    const title = $('title').text();
    console.log(`Scraped ${url} - Title: ${title}`);
  } catch (error) {
    console.error(`Error scraping ${url}: ${error.message}`);
  }
}

// Enqueue scraping tasks for each site
sites.forEach((site) => {
  queue.add(() => scrapeSite(site));
});

// Wait for all tasks to complete
queue.onIdle().then(() => {
  console.log('All scraping tasks completed.');
});

This example uses axios for making HTTP requests, cheerio for HTML parsing, and p-queue for controlling concurrency.

Run the Script:

node your_scraper_script.js

Adjust the sites array with the URLs you want to scrape.

This example uses a simple queue system to control the number of concurrent requests, preventing potential issues with rate limiting or overwhelming the target websites. However, be mindful of the websites' terms of service and robots.txt rules to avoid scraping restrictions.

To change the proxy settings on an Android device, follow these steps:

1. Open the "Settings" app on your Android device.

2. Scroll down and tap on "Network & Internet" or "Connections," depending on your device's Android version and manufacturer.

3. Tap on "Wi-Fi" if you want to change the proxy settings for Wi-Fi connections, or "Mobile networks" if you want to change the proxy settings for cellular data.

4. If you're changing the settings for Wi-Fi, tap on the Wi-Fi network you're currently connected to. If you're changing the settings for mobile networks, tap on "Advanced options" or "Access Point Names (APN)."

5. Look for the "Proxy" or "Access Point" section. Tap on it to access the proxy settings.

6. You will see options to enter the proxy server's IP address and port number. Enter the required information for the proxy server you want to use. Some proxy servers may also require you to enter a username and password.

7. Once you've entered the proxy server details, save your changes by tapping on the "Save" or "Apply" button.

Getting a resident proxy for free can be challenging, as many free proxies are often unreliable, slow, or may pose security risks. However, you can try the following methods to find free resident proxies:

1. Proxy lists: Search for reputable proxy lists that provide a collection of free proxies. Be cautious when choosing a list, as some may contain malicious or unreliable proxies.
2. Online forums and communities: Look for online forums or communities where people share and discuss free proxies. Be cautious when using free proxies from these sources, as they may not be reliable or secure.
3. Social media: Some users may share their free resident proxies on social media platforms. However, be cautious when using proxies from social media, as they may not be reliable or secure.
4. Web scraping tools: Use web scraping tools to extract proxy information from websites that list free proxies. Be cautious when using this method, as it may be against the terms of service of some websites.

Please note that using free proxies can expose you to various risks, so it's essential to be cautious and aware of the potential dangers. If you're unsure about using a free proxy, it may be best to avoid them and opt for a paid proxy service instead. Paid proxy services typically offer better reliability, speed, and security.
