The Proxy Rebellion

To assign a proxy server to an Android or iOS access point, follow these steps:

Open the "Settings" section. Go to the "Wi-Fi" tab. Select your access point. Click on "Proxy". Use manual setup and specify the data of proxy. Save the settings.

To enable proxies in your MacBook, you need to go to "System Preferences" (from the "Apple" menu), then open "Network", then - specify the type of connection you are using. Then select "Advanced Settings" (can be named as "Advanced"), then click on "Proxy". And then - either set the parameters manually, or specify a configuration file.

If you are parsing a site using JSoup in a Java application and you want to introduce a delay between requests to avoid being blocked or rate-limited by the website, you can use Thread.sleep to pause the execution for a specified duration. Here's a basic example

First, make sure you have the JSoup library included in your project. If you're using Maven, you can add the following dependency to your pom.xml:

    org.jsoup
    jsoup
    1.14.3 

Now, here's an example Java program using JSoup with a delay between requests:

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

import java.io.IOException;

public class WebScraperWithDelay {

    public static void main(String[] args) {
        // Replace with the URL you want to scrape
        String url = "https://example.com";
        
        // Number of milliseconds to wait between requests
        long delayMillis = 2000; // 2 seconds
        
        try {
            for (int i = 0; i < 5; i++) {
                // Make the HTTP request using JSoup
                Document document = Jsoup.connect(url).get();

                // Process the document as needed
                System.out.println("Title: " + document.title());

                // Introduce a delay between requests
                Thread.sleep(delayMillis);
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

In this example:

1. Jsoup.connect(url).get() is used to make an HTTP request and retrieve the HTML document from the specified URL.
2. Thread.sleep(delayMillis) introduces a delay of 2 seconds between requests. You can adjust the value of delayMillis based on your needs.

To log into an account using Selenium, you need to locate the login form elements, enter the login credentials, and submit the form. The exact steps may vary depending on the website's structure, but here's a general example using C#:

Install the required NuGet packages:

Install-Package OpenQA.Selenium.Chrome.WebDriver -Version 3.141.0
Install-Package OpenQA.Selenium.Support.UI -Version 3.141.0

Create a method to log into an account:

using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;
using System;

public static void LoginToAccount(IWebDriver driver, string username, string password)
{
    // Locate the username field
    IWebElement usernameField = driver.FindElement(By.Id("username"));
    usernameField.SendKeys(username);

    // Locate the password field
    IWebElement passwordField = driver.FindElement(By.Id("password"));
    passwordField.SendKeys(password);

    // Locate the login button and click it
    IWebElement loginButton = driver.FindElement(By.Id("login-button"));
    loginButton.Click();

    // Wait for the login process to complete (optional)
    WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
    wait.Until(d => d.FindElement(By.Id("logout-link")));
}

Use the LoginToAccount method in your test code:

using OpenQA.Selenium;
using System;

namespace SeleniumLoginExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Set up the WebDriver
            IWebDriver driver = new ChromeDriver();
            driver.Manage().Window.Maximize();

            // Navigate to the login page
            driver.Navigate().GoToUrl("https://www.example.com/login");

            // Wait for the login form to load
            WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
            IWebElement loginForm = wait.Until(x => x.Id == "login-form");

            // Log in to the account
            LoginToAccount(driver, "your_username", "your_password");

            // Perform any additional actions as needed

            // Close the browser
            driver.Quit();
        }
    }
}

In this example, we first create a method called LoginToAccount that takes an IWebDriver instance, a username, and a password as input. Inside the method, we locate the username field, password field, and login button using their respective IDs, and then enter the credentials and click the login button.

In the test code, we set up the WebDriver, navigate to the login page, and wait for the login form to load. Then, we call the LoginToAccount method with the required credentials. After logging in, you can perform any additional actions as needed.

Remember to replace "https://www.example.com/login", "your_username", and "your_password" with the actual login page URL and your credentials.

A proxy in data centers is usually a separate server that processes incoming requests and then distributes them to the submitted addresses (or IP). Also through the proxy it is possible to allocate a specific user a separate IP address for connection (for example, if he needs a virtual server).
