Collabora Reverse Proxy

Open the browser settings and go to the "Advanced" section. Click on "System" and then, in the window that opens, click on "Open proxy settings for computer". A window will appear in front of you, showing all the current settings. Another way to find out the http proxy is to download and install the SocialKit Proxy Checker utility on your computer.

To run Firefox with Selenium and connected extensions, you'll need to use the FirefoxDriverService and FirefoxOptions. You can also set the path to the Firefox executable and the path to the extensions' .xpi files using the FirefoxBinary and FirefoxProfile classes. Here's an example of how to do this:

Install the required NuGet packages:

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

Create a method to add extensions to the Firefox profile:

using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using System.IO;
using System.Linq;

public static IWebDriver CreateFirefoxDriverWithExtensions(string[] extensionPaths)
{
    var firefoxOptions = new FirefoxOptions();
    var firefoxBinary = new FirefoxBinary(Path.GetDirectoryName(FirefoxDriverService.DefaultServicePath));
    var firefoxProfile = new FirefoxProfile();

    // Add extensions to the Firefox profile
    foreach (var extensionPath in extensionPaths)
    {
        var extensionFile = new FileInfo(extensionPath);
        if (extensionFile.Exists)
        {
            firefoxProfile.AddExtension(extensionPath);
        }
    }

    firefoxOptions.BinaryLocation = firefoxBinary.Path;
    firefoxOptions.Profile = firefoxProfile;

    // Start the FirefoxDriverService with the specified Firefox binary
    var driverService = FirefoxDriverService.CreateDefaultService(firefoxBinary.Path, FirefoxDriverService.DefaultPort);
    driverService.EnableVerboseLogging = true;

    // Create the FirefoxDriver with the specified options
    var driver = new FirefoxDriver(driverService, firefoxOptions);

    return driver;
}

Use the CreateFirefoxDriverWithExtensions method in your test code:

using OpenQA.Selenium;
using System;

namespace SeleniumFirefoxExtensionsExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Paths to the extensions' .xpi files
            string[] extensionPaths = new[]
            {
                @"path\to\extension1.xpi",
                @"path\to\extension2.xpi"
            };

            // Create the FirefoxDriver with connected extensions
            using (var driver = CreateFirefoxDriverWithExtensions(extensionPaths))
            {
                // Set up the WebDriver
                driver.Manage().Window.Maximize();

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

                // Perform any additional actions as needed

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

In this example, we first create a method called CreateFirefoxDriverWithExtensions that takes an array of extension paths as input. Inside the method, we set up the FirefoxOptions, FirefoxBinary, and FirefoxProfile to include the specified extensions. Then, we start the FirefoxDriverService with the specified Firefox binary and create the FirefoxDriver with the specified options.

In the test code, we call the CreateFirefoxDriverWithExtensions method with the paths to the extensions' .xpi files and use the returned IWebDriver instance to interact with the browser.

Remember to replace "path\to\extension1.xpi" and "path\to\extension2.xpi" with the actual paths to the extensions' .xpi files you want to connect.

To send a UDP request to a STUN server in C++, you can use the following example code. This example uses the boost::asio library for handling asynchronous I/O operations and boost::beast for handling UDP communication. Make sure you have the Boost library installed on your system before running this code.

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 

namespace http = boost::beast::http;

using tcp = boost::asio::ip::tcp;
using udp = boost::asio::ip::udp;

int main(int argc, char* argv[]) {
  if (argc != 3) {
    std::cerr << "Usage: stun_udp_request  " << std::endl;
    return EXIT_FAILURE;
  }

  boost::asio::io_context ioc;
  udp::resolver resolver(ioc);
  udp::resolver::results_type results = resolver.resolve(argv[1], argv[2]);

  if (results.empty()) {
    std::cerr << "Cannot resolve: " << argv[1] << ":" << argv[2] << std::endl;
    return EXIT_FAILURE;
  }

  udp::socket udp_socket(ioc);
  udp_socket.connect(results.begin()->endpoint());

  // Prepare the STUN Binding Request
  std::string stun_request =
      "BINDING_REQUEST\r\n"
      "MIXED_RELAY\r\n"
      "USER-AGENT: STUN-UDP-Example\r\n"
      "\r\n";

  // Send the STUN Binding Request
  boost::system::error_code ignored_error;
  udp_socket.send_to(boost::asio::buffer(stun_request), results.begin()->endpoint(), 0, ignored_error);

  // Receive the STUN Binding Response
  boost::beast::flat_buffer buffer;
  http::response response;
  udp_socket.receive_message(buffer, response);

  // Print the STUN Binding Response
  std::cout << "STUN Binding Response:\n";
  std::cout << response.what() << std::endl;

  return EXIT_SUCCESS;
}

To compile the example, you can use the following command:

g++ -std=c++17 -o stun_udp_request stun_udp_request.cpp -lboost_system -lboost_as

To scrape all HTML content from a website using Scrapy, you need to create a spider that visits each page of the website and extracts the HTML content. Here's a simple example:

Create a Scrapy Project:
If you haven't already, create a Scrapy project by running the following commands in your terminal or command prompt:

scrapy startproject myproject
cd myproject

Define a Spider:
Open the spiders directory in your project and create a spider (e.g., html_spider.py). Edit the spider file with the following content:

import scrapy

class HtmlSpider(scrapy.Spider):
    name = 'html_spider'
    start_urls = ['http://example.com']  # Start with the main page of the website

    def parse(self, response):
        # Extract HTML content and yield it
        html_content = response.text
        yield {
            'url': response.url,
            'html_content': html_content
        }

        # Follow links to other pages (if needed)
        for next_page_url in response.css('a::attr(href)').extract():
            yield scrapy.Request(url=next_page_url, callback=self.parse)

This spider, named html_spider, starts with the main page (start_urls) and extracts the HTML content. It then follows links (a::attr(href)) to other pages and extracts their HTML content as well.

Run the Spider:
Run your spider using the following command:

scrapy crawl html_spider -o output.json

This command will execute the html_spider and save the output in a JSON file named output.json. Each item in the JSON file will contain the URL and HTML content of a page.

The proxy domain most often refers to the IP address where the server is located. It can only "learn" the IP address of the user when processing the traffic. But in most cases it does not store such information later for security reasons.
