Kat UK Proxy

Open the Telegram app, and then go to "Settings. Find "Data and Drive", then tap "Proxy". Activate the "Use proxy" toggle switch, then select the desired option from the suggested list. The setting is successfully completed.

A firewall is responsible for filtering packets of traffic. For example, it blocks access to the Internet for certain applications. There are many more options for using a proxy. But if you install special software, it can also be used for such purposes.

To organize multi-threaded scraping through a proxy in C#, you can use the HttpClient class along with tasks and threads. Additionally, you may use proxy rotation to avoid rate limiting and bans. Here's a basic example to get you started:

using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Threading.Tasks;

class Program
{
    static async Task Main()
    {
        // List of proxy URLs
        List proxyList = new List
        {
            "http://proxy1.com:8080",
            "http://proxy2.com:8080",
            // Add more proxies as needed
        };

        // Create HttpClient instances with a different proxy for each thread
        List httpClients = CreateHttpClients(proxyList);

        // List of URLs to scrape
        List urlsToScrape = new List
        {
            "https://example.com/page1",
            "https://example.com/page2",
            // Add more URLs as needed
        };

        // Create tasks for each URL
        List tasks = new List();
        foreach (string url in urlsToScrape)
        {
            tasks.Add(Task.Run(() => ScrapeUrl(url, httpClients)));
        }

        // Wait for all tasks to complete
        await Task.WhenAll(tasks);

        // Dispose of HttpClient instances
        foreach (HttpClient client in httpClients)
        {
            client.Dispose();
        }
    }

    static List CreateHttpClients(List proxies)
    {
        List clients = new List();
        foreach (string proxy in proxies)
        {
            var httpClientHandler = new HttpClientHandler
            {
                Proxy = new WebProxy(proxy),
                UseProxy = true,
            };

            clients.Add(new HttpClient(httpClientHandler));
        }

        return clients;
    }

    static async Task ScrapeUrl(string url, List httpClients)
    {
        // Select a random proxy for this request
        var random = new Random();
        var httpClient = httpClients[random.Next(httpClients.Count)];

        try
        {
            // Make the request using the selected proxy
            HttpResponseMessage response = await httpClient.GetAsync(url);

            // Check if the request was successful
            if (response.IsSuccessStatusCode)
            {
                string content = await response.Content.ReadAsStringAsync();
                // Process the content as needed
                Console.WriteLine($"Scraped {url}: {content.Length} characters");
            }
            else
            {
                Console.WriteLine($"Failed to scrape {url}. Status code: {response.StatusCode}");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error scraping {url}: {ex.Message}");
        }
    }
}

In this example:

The CreateHttpClients function creates a list of HttpClient instances, each configured with a different proxy from the provided list.

The ScrapeUrl function performs the actual scraping for a given URL using a randomly selected proxy.

The Main method creates tasks for each URL to be scraped and waits for all tasks to complete.

Setting up a proxy server correctly involves choosing the right hardware, selecting a suitable proxy server software, configuring the server, and securing the connection. Here's a step-by-step guide to help you set up a proxy server:

1. Choose the right hardware: Select a server or computer with adequate resources (CPU, RAM, and storage) to handle the expected number of connections and data transfer rates. You may also want to consider using dedicated hardware or a virtual private server (VPS) for better performance and security.

2. Select proxy server software: There are various proxy server software options available, such as Privoxy, Squid, and PacketFence. Choose a software that suits your needs, considering factors like ease of use, performance, and compatibility with your operating system.

3. Install the proxy server software: Follow the instructions provided by the software vendor to install the proxy server software on your chosen hardware. Make sure to download the software from a reputable source and use the latest version to ensure security and compatibility.

4. Configure the server: Configure the proxy server software according to your requirements. This may include setting up the IP address, port number, and authentication methods (e.g., username and password, IP filtering, or HTTP authentication). You can also configure additional settings, such as caching, bandwidth limits, and access control lists.

5. Secure the connection: Ensure that your proxy server is secure by using encryption (e.g., SSL/TLS) and implementing firewalls or intrusion detection systems. Regularly update the software and apply security patches to minimize vulnerabilities.

6. Test the proxy server: Once the server is set up and configured, test its functionality and performance. Verify that it can handle incoming connections, forward requests correctly, and maintain the desired level of anonymity or security.

7. Share the proxy server: If you want to share your proxy server with others, provide them with the IP address, port number, and any necessary authentication credentials. Be cautious when sharing your proxy server, as it can expose your IP address and bandwidth to others, potentially leading to security risks or abuse.

There are many free VPN services. But it is not safe to use them. After all, they are just engaged in parsing. That is, they collect information about users. Most often - their IP-addresses, as well as text data (these are search queries and their personal information).
