Cloudflare DNS Proxy

Click on the three bars located in the upper right corner and click on "Settings". When the settings page appears in front of you, go down to the "System" section and click on "Proxy settings". In the window that appears, click on "Network settings" and then check the box next to "Use a proxy server for local connections". Now all you have to do is enter the IP address and port of the proxy server, and then save your changes.

The provider, when the user uses a VPN, "sees" only the encrypted traffic, as well as the address of the remote server to which the request is sent. But it is impossible to determine which site the user is visiting and what data is being sent.

JSON scraping typically involves extracting data from a JSON response obtained from an API. When you mention doing JSON scraping sequentially, it could mean processing items in the JSON response one after another. Below is a simple example in Python that demonstrates sequential processing of JSON data:

import requests

def fetch_data(url):
    response = requests.get(url)
    return response.json()

def process_item(item):
    # Replace this with your actual processing logic
    print("Processing item:", item)

def scrape_sequentially(api_url):
    data = fetch_data(api_url)

    # Assuming the JSON response is a list of items
    if isinstance(data, list):
        for item in data:
            process_item(item)
    else:
        print("Invalid JSON format. Expected a list of items.")

# Replace 'https://example.com/api/data' with the actual API URL
api_url = 'https://example.com/api/data'
scrape_sequentially(api_url)

In this example:

1. The fetch_data function sends a GET request to the specified API URL and returns the JSON response.
2. The process_item function represents the logic you want to apply to each item in the JSON response.
3. The scrape_sequentially function fetches the JSON data, checks if it's a list, and then iterates through each item, applying the processing logic sequentially.

Make sure to replace the placeholder URL 'https://example.com/api/data' with the actual URL of the API you want to scrape.

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.

Although free proxies are popular, they are far from being flawless in their work. Many of their IP addresses are blacklisted by popular resources, and the data transfer speed and stability are very unreliable. When choosing a proxy, keep in mind that the new version of IPv6 is not supported by most websites. Note also that proxies are divided into private and public, statistical and dynamic, and support different network protocols.
