Momo Proxy

To find out the port of the proxy server, you just need to use any browser (Yandex Browser, Opera, Google Chrome). Then you need to follow the algorithm:

Start the browser. Go to "Settings". In the search box enter the query "proxy". Click on "Proxy settings". In the window that opens, select "Network settings". This will open a tab with the IP address and port of the proxy server.

It seems there might be a confusion in your request. Polly is a resilience and transient-fault-handling library in C# for dealing with issues like network failures, timeouts, and other transient errors. It is not directly related to parsing courses or web scraping.

If you are looking to parse a course from a website using C#, you might want to use a combination of HTTP requests and HTML parsing libraries. Here's a basic example using the HtmlAgilityPack library for HTML parsing and HttpClient for making HTTP requests

Install HtmlAgilityPack:

You can install the HtmlAgilityPack library using NuGet Package Manager Console:

Install-Package HtmlAgilityPack

Example Code

Here's a simple example of how you might use HttpClient and HtmlAgilityPack to parse course information from a website:

using System;
using System.Net.Http;
using HtmlAgilityPack;

class Program
{
    static async System.Threading.Tasks.Task Main(string[] args)
    {
        // URL of the course page
        string courseUrl = "https://example.com/courses";

        // Make an HTTP request to get the HTML content
        using (HttpClient client = new HttpClient())
        {
            string htmlContent = await client.GetStringAsync(courseUrl);

            // Use HtmlAgilityPack to parse the HTML
            HtmlDocument doc = new HtmlDocument();
            doc.LoadHtml(htmlContent);

            // Extract course information (modify as per the HTML structure)
            HtmlNodeCollection courseNodes = doc.DocumentNode.SelectNodes("//div[@class='course']");
            if (courseNodes != null)
            {
                foreach (HtmlNode courseNode in courseNodes)
                {
                    string courseTitle = courseNode.SelectSingleNode(".//h2")?.InnerText.Trim();
                    string courseDescription = courseNode.SelectSingleNode(".//p")?.InnerText.Trim();

                    Console.WriteLine($"Title: {courseTitle}");
                    Console.WriteLine($"Description: {courseDescription}");
                    Console.WriteLine();
                }
            }
            else
            {
                Console.WriteLine("No course information found on the page.");
            }
        }
    }
}

This is a basic example, and you'll need to adapt it based on the actual HTML structure of the course page you are working with.

Selenium is a powerful tool for automating web browsers, and it has various tools and bindings for different programming languages. If you are specifically interested in Selenium tools for JavaScript, you'll likely be working with the Selenium WebDriver bindings for JavaScript. Here are the key components and tools related to using Selenium with JavaScript

WebDriverJS (Selenium WebDriver for JavaScript)

WebDriverJS, also known as selenium-webdriver for JavaScript, is the official Selenium WebDriver binding for JavaScript. It allows you to write automated tests in JavaScript to control web browsers.

You can install WebDriverJS using npm:

npm install selenium-webdriver

Example code snippet using WebDriverJS

const { Builder, By, Key, until } = require('selenium-webdriver');

(async function example() {
  let driver = await new Builder().forBrowser('chrome').build();
  try {
    await driver.get('https://www.example.com');
    await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN);
    await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
  } finally {
    await driver.quit();
  }
})();

Protractor

Protractor is an end-to-end testing framework specifically designed for Angular applications. It uses WebDriverJS internally and extends it to provide additional features for Angular applications.

Protractor can be installed using npm:

npm install -g protractor

Example Protractor configuration file:

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['example-spec.js']
};

WebdriverIO

WebdriverIO is another popular JavaScript framework for end-to-end testing. It is built on top of WebDriverJS and provides a simplified interface for interacting with browsers.

WebdriverIO can be installed using npm:

npm install webdriverio

Example WebdriverIO test script

const { remote } = require('webdriverio');

(async () => {
    const browser = await remote({
        capabilities: {
            browserName: 'chrome'
        }
    });

    await browser.url('https://www.example.com');
    const title = await browser.getTitle();
    console.log('Title:', title);

    await browser.deleteSession();
})();

Nightwatch.js

Nightwatch.js is a testing framework built on top of WebDriverJS that simplifies the process of writing and executing end-to-end tests.

Nightwatch.js can be installed using npm:

npm install nightwatch

Example Nightwatch.js configuration file

module.exports = {
  'Demo Test': function (browser) {
    browser
      .url('https://www.example.com')
      .waitForElementVisible('body')
      .assert.title('Example Domain')
      .end();
  }
};

To play games or access online services via a proxy, you need to configure your device or application to use the proxy server. This process varies depending on the platform and application you are using. Here's a general guide on how to play games or access online services via a proxy:

Choose a proxy server: Find a reliable proxy server that suits your needs. You can use a free proxy or a paid proxy service, depending on your requirements.

Configure your device or application: To use a proxy server, you need to configure your device or application to route its internet traffic through the proxy server.

A proxy is just used to bypass torrent download blocking through your ISP's network. Separately, the proxy server can block the host, that is, the owner of the site where the torrent files are posted. But it happens mostly due to malicious violations of the rules for using such a resource (for example, "cheating" rating).
