Proxy Celcom

Technically, a proxy is an ordinary computer or server connected to a network (local or Internet). It accepts traffic from the user, redirects it to the address that was specified in the request. And then receives the response from the server and transmits it to the user's equipment. That is, it is actually an intermediary.

The proxy settings in Zoom are configured through the regular Windows settings. To do this, you can use the command inetcpl.cpl in "Run". Next, you need to go to the "Connection" tab, click on "Network Setup". In the dialog box that opens, select "Proxy server" and set the required parameters. As a port, you can use 80 and 443.

There are HTTP proxy, FTP proxy, SOCKS proxy, SMTP proxy, CGI proxy. They differ only in the data transmission protocol used and the purpose for which they are used. For example, SMTP proxy allows you to organize a secure server for e-mail.

Here are some general guidelines to approach scraping protected sites:

1. Check Terms of Service:

   • Review the terms of service, robots.txt file, and any other usage policies provided by the website. Some websites explicitly prohibit scraping.

2. Contact the Website Owner:

   • If you have a legitimate reason for scraping and the website provides contact information, consider reaching out to the website owner or administrator to request permission.

3. Use Official APIs:

   • Many websites offer official APIs that allow controlled access to their data. Using an API is a sanctioned and structured way to obtain information.

4. Simulate Human Behavior:

   • Mimic human behavior by setting appropriate headers, handling cookies, and introducing delays between requests. This helps avoid detection mechanisms that may identify automated bots.

5. Handle CAPTCHAs:

   • Some sites may use CAPTCHAs to prevent automated access. Implement mechanisms to handle CAPTCHAs if they are encountered.

6. Use Proxy Servers:

   • Rotate IP addresses using proxy servers to avoid IP-based blocking. However, be aware that some sites may block common proxy server IP ranges.

7. Avoid Aggressive Scraping:

   • Limit the frequency and volume of your requests to avoid overloading the server. Implement rate limiting and throttling to mimic human browsing behavior.

8. Stay Informed:

   • Monitor the website for changes in its structure or policies. Adjust your scraping strategy accordingly to adapt to any modifications.

To disable WebRTC in Chrome using Selenium ChromeDriver in C#, you can use ChromeOptions to set the necessary command-line arguments. Here's an example:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

class Program
{
    static void Main()
    {
        ChromeOptions chromeOptions = new ChromeOptions();

        // Disable WebRTC
        chromeOptions.AddArgument("--disable-webrtc");

        // Other options (customize as needed)
        // chromeOptions.AddArgument("--use-fake-device-for-media-stream");
        // chromeOptions.AddArgument("--use-fake-ui-for-media-stream");

        IWebDriver driver = new ChromeDriver(chromeOptions);

        // Your Selenium script...

        driver.Quit();
    }
}

In this example:

--disable-webrtc is added as a command-line argument to disable WebRTC in Chrome.

Additional options related to WebRTC are provided in comments. Uncomment and customize them based on your specific requirements.

Make sure to replace the "Your Selenium script..." comment with the actual logic of your Selenium script.
