Jsoup is a Java library for working with HTML documents. To scrape links using Jsoup, you can use its selector syntax to target the anchor elements and then extract the href attributes. Here's a simple example:

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import java.io.IOException;

public class LinkScraper {
    public static void main(String[] args) {
        String url = "https://example.com";

        try {
            // Connect to the website and get the HTML document
            Document document = Jsoup.connect(url).get();

            // Select all anchor elements
            Elements links = document.select("a");

            // Iterate over each anchor element and print the href attribute
            for (Element link : links) {
                String href = link.attr("href");
                System.out.println("Link: " + href);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Make sure to replace the url variable with the URL of the website you want to scrape.

This example connects to the specified URL, retrieves the HTML document, selects all anchor elements using the "a" selector, and then iterates over them to print the href attributes.

You need to include the Jsoup library in your project. If you are using Maven, you can add the following dependency to your pom.xml:

    org.jsoup
    jsoup
    1.14.3 

To install the Selenium library in C# for Visual Studio, you can use the NuGet Package Manager, which is integrated into Visual Studio. Follow these steps to install Selenium in your C# project:

1. Open Visual Studio:

   • Launch Visual Studio and open your C# project.

2. Open the Package Manager Console:

   • Go to View -> Other Windows -> Package Manager Console to open the Package Manager Console.

3. Run the Install-Package Command:

   • In the Package Manager Console, run the following command to install the Selenium.WebDriver package:

Install-Package Selenium.WebDriver

• • Press Enter to execute the command. This will download and install the Selenium WebDriver package and its dependencies.

• Verify Installation:

  • After the installation is complete, you should see output indicating that the package has been installed successfully.

• Install Selenium.Support (Optional):

  • Depending on your requirements, you may also want to install Selenium.Support, which includes additional support classes and utilities for Selenium. Run the following command:

Install-Package Selenium.Support

Add Using Statements in Your Code:

• In your C# code file, add the following using statements at the top:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;  // Use the appropriate browser namespace (e.g., Firefox, Edge, etc.)

• • Choose the appropriate browser namespace based on the WebDriver you plan to use (e.g., Chrome, Firefox).

• Download WebDriver Executable (Optional):

  • If you are using a specific browser (e.g., Chrome, Firefox), you need to download the corresponding WebDriver executable.

  • Place the WebDriver executable in a location accessible to your project.

• Instantiate WebDriver in Your Code:

  • In your C# code, instantiate the WebDriver using the downloaded WebDriver executable path. For example, for Chrome:

IWebDriver driver = new ChromeDriver("path/to/chromedriver");

8. • Replace "path/to/chromedriver" with the actual path to your ChromeDriver executable.

   • Ensure that you manage the WebDriver instance properly (e.g., closing it after use).

That's it! You have successfully installed the Selenium library in your C# project. You can now use the Selenium WebDriver to automate browser interactions in your C# application.

In the "System Settings" section, open the "Network" tab, and then, when you highlight the active connection, click "Advanced". Here, in the "Proxies" tab, tick only the HTTP proxy if you do not intend to use other types of proxies temporarily. Enter the address of your proxy server and its port in the designated fields and click "OK".

It means organizing a connection through several VPN-servers at once. It is used to protect confidential data as much as possible or to hide one's real IP address. This principle of connection is used, for example, in the TOR-browser. That is, when all traffic is sent immediately through a chain of proxy servers.
