Ice Core Proxy

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 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.

A proxy address, also known as a proxy URL or proxy server address, is the address used to connect to a proxy server. It typically consists of the following components:

Protocol: The protocol used to connect to the proxy server, such as HTTP, HTTPS, or SOCKS.

Username and password (optional): Authentication credentials for accessing the proxy server, if required.

Proxy server IP address or hostname: The IP address or hostname of the proxy server.

Port number: The port number on which the proxy server is listening for connections.

A proxy address might look like this:

http://:@:/

Here, and represent the proxy server's authentication credentials, is the proxy server's IP address or hostname, and is the proxy server's port number.

To keep only unique external links while scraping with Scrapy, you can use a set to track the visited external links and filter out duplicates. Here's an example spider that demonstrates how to achieve this:

import scrapy
from urllib.parse import urlparse, urljoin

class UniqueLinksSpider(scrapy.Spider):
    name = 'unique_links'
    start_urls = ['http://example.com']  # Replace with the starting URL of your choice
    visited_external_links = set()

    def parse(self, response):
        # Extract all links from the current page
        all_links = response.css('a::attr(href)').extract()

        for link in all_links:
            full_url = urljoin(response.url, link)

            # Check if the link is external
            if urlparse(full_url).netloc != urlparse(response.url).netloc:
                # Check if it's a unique external link
                if full_url not in self.visited_external_links:
                    # Add the link to the set of visited external links
                    self.visited_external_links.add(full_url)

                    # Yield the link or process it further
                    yield {
                        'external_link': full_url
                    }

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

- visited_external_links is a class variable that keeps track of the unique external links across all instances of the spider.
- The parse method extracts all links from the current page.
- For each link, it checks if it is an external link by comparing the netloc (domain) of the current page and the link.
- If the link is external, it checks if it is unique by looking at the visited_external_links set.
- If the link is unique, it is added to the set, and the spider yields the link or processes it further.
- The spider then follows links to other pages, recursively calling the parse method.

Remember to replace the start_urls with the URL from which you want to start scraping.

Go to settings, find the "Security" menu and click on "Unblock security settings". You will be prompted to agree to the changes, which you will need to confirm by clicking "Yes", which will unlock the "Allow unsupervised access" item. Now click on the text or checkbox to activate the function. On the computer from which you plan to connect remotely, you will need to enter the ID of the first computer and click on "Connect".
