Google Proxy Scraper

A proxy can be used for anonymous web surfing. After all, the connection is made through an intermediate server. And all the sites visited by the user will see the IP address of the proxy server, not the user himself. It can also be used to access resources that are only available to the citizens of a particular country.

Scraping Razor pages in a separate AppDomain in C# is an advanced scenario, and it's not a common approach. However, if you have specific requirements that necessitate this, you can achieve it by creating a separate AppDomain for the scraping task. Keep in mind that creating a new AppDomain introduces complexity, and you need to consider potential security and performance implications.

Below is a basic example of how you can use a separate AppDomain for scraping Razor pages. In this example, I'm assuming that you want to perform scraping logic within the separate AppDomain:

using System;
using System.Reflection;

class Program
{
    static void Main()
    {
        // Create a new AppDomain
        AppDomain scraperDomain = AppDomain.CreateDomain("ScraperDomain");

        try
        {
            // Load and execute the scraping logic in the separate AppDomain
            scraperDomain.DoCallBack(() =>
            {
                // This code runs in the separate AppDomain

                // Load necessary assemblies (e.g., your scraping library)
                Assembly.Load("YourScrapingLibrary");

                // Perform your scraping logic
                RazorPageScraper scraper = new RazorPageScraper();
                scraper.Scrape();
            });
        }
        finally
        {
            // Unload the AppDomain to release resources
            AppDomain.Unload(scraperDomain);
        }
    }
}

// RazorPageScraper class in a separate assembly or namespace
public class RazorPageScraper
{
    public void Scrape()
    {
        // Your scraping logic here
        Console.WriteLine("Scraping Razor pages...");
    }
}

In this example:

1. The AppDomain is created using AppDomain.CreateDomain.
2. The scraping logic is executed inside the separate AppDomain using AppDomain.DoCallBack.
3. The RazorPageScraper class, containing the scraping logic, is assumed to be in a separate assembly or namespace.

Keep in mind:

• Security: Loading and executing code in a separate AppDomain may have security implications. Ensure that you understand the risks and take appropriate precautions.
• Performance: Creating a new AppDomain incurs overhead. It might not be suitable for lightweight scraping tasks.

This example is simplified, and you need to adapt it based on your specific requirements and the structure of your scraping code.

Changing the WebRTC (Web Real-Time Communication) value in Selenium involves modifying the browser's configuration options. WebRTC settings are not directly exposed through Selenium WebDriver, so you need to use browser-specific options or preferences.

Below are examples for changing WebRTC settings in Chrome and Firefox using Selenium in Python. Keep in mind that the availability of certain options may vary depending on the browser version, and these examples may need adjustments based on your specific requirements.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()

# Disable WebRTC
chrome_options.add_argument('--disable-webrtc')

# Other options (customize as needed)
# chrome_options.add_argument('--use-fake-device-for-media-stream')
# chrome_options.add_argument('--use-fake-ui-for-media-stream')

driver = webdriver.Chrome(chrome_options=chrome_options)

# Your Selenium script...

driver.quit()

In this example, --disable-webrtc is used to disable WebRTC. You can explore other Chrome command-line options related to WebRTC here.

Firefox

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

firefox_options = Options()

# Disable WebRTC
firefox_options.set_preference('media.peerconnection.enabled', False)

# Other preferences (customize as needed)
# firefox_options.set_preference('media.navigator.streams.fake', True)
# firefox_options.set_preference('media.navigator.permission.disabled', True)

driver = webdriver.Firefox(firefox_options=firefox_options)

# Your Selenium script...

driver.quit()

In this example, media.peerconnection.enabled is set to False to disable WebRTC in Firefox. Additional preferences can be adjusted based on your needs. You can find more Firefox preferences related to WebRTC here.

Remember that changing browser preferences may have implications on the behavior of your application, and modifying settings like WebRTC should be done responsibly and in accordance with the terms of service of the websites you are interacting with.

To catch a dynamic element using Selenium, you can use various methods depending on the specifics of the element and the browser you are using. Here are some common approaches:

Using WebDriverWait and expected_conditions:

The WebDriverWait class is used to wait for a specific condition to be met before proceeding with the script. You can use the expected_conditions module to define the condition you want to wait for.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Chrome()
driver.get("https://www.example.com")

dynamic_element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, "dynamic-element-id"))
)

In this example, the script will wait up to 10 seconds for the element with the ID dynamic-element-id to appear on the page. Once the element is present, it can be interacted with or located.

Using JavaScript to interact with dynamic elements:

You can use the execute_script() method to run JavaScript code in the context of the current page. This allows you to interact with dynamic elements that may not be accessible through the regular Selenium methods.

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.example.com")

dynamic_element = driver.execute_script("return document.getElementById('dynamic-element-id');")

In this example, the script runs JavaScript code to get a reference to the element with the ID dynamic-element-id. You can then interact with the element using JavaScript or Selenium methods.

Using actions with dynamic elements:

The actions module allows you to simulate user interactions, such as mouse movements and clicks. You can use this module to interact with dynamic elements that require user-like interaction.

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

driver = webdriver.Chrome()
driver.get("https://www.example.com")

dynamic_element = driver.find_element(By.ID, "dynamic-element-id")
actions = ActionChains(driver)
actions.move_to_element(dynamic_element).perform()
actions.click(dynamic_element).perform()

In this example, the script moves the mouse cursor to the dynamic element and simulates a click, which may be necessary if the element is interactive or requires user-like interaction.

Remember to replace "https://www.example.com", "dynamic-element-id", and other elements with the actual values for the website you are working with. Also, ensure that the browser driver (e.g., ChromeDriver for Google Chrome) is installed and properly configured in your environment.

Technically, ISP can block only some intermediary servers by IP-addresses. But it's impossible to block absolutely all VPN-servers, because there are so many of them and their addresses are constantly changing. Accordingly, in this case, you just need to use another VPN-server.
