Proxy Indo

In the upper right corner of the browser, click "Settings and Other", and then select the "Options" tab in the window that appears. Once the "General" window opens, locate the "Advanced" tab and click "Open proxy settings" in the menu that appears. Here, in the line "Use a proxy server", select "On". In the "Address" field, you must specify the IP address of the proxy, and in the "Port" field - the port of the proxy. The last thing to do is to click "Save".

CefSharp is a .NET wrapper for the Chromium Embedded Framework (CEF) that allows you to embed a Chromium browser in your .NET applications. While CefSharp doesn't have a direct replacement for Selenium functions, you can use its own methods to interact with the browser and perform similar actions.

To find elements using XPath in CefSharp, you can use the GetElementById(), GetElementsByClassName(), GetElementsByTagName(), and GetElementsByAttribute() methods provided by the CEFBrowser and CefV8Handler classes.

Here's an example of how you can find elements using XPath in CefSharp:

First, install the CefSharp NuGet package in your project:

Install-Package CefSharp.Minimal

Use the following code to create a CefSharp browser and load a webpage:

using CefSharp.WinForms;
using System;
using System.Drawing;
using System.Windows.Forms;

namespace CefSharpExample
{
    public class Program
    {
        [STAThread]
        public static void Main(string[] args)
        {
            CefSettings settings = new CefSettings();
            settings.BrowserSubprocessPath = "path/to/cef/browser_win32_x64.exe";
            settings.CefCommandLineArgs.Add("--disable-gpu");
            settings.CefCommandLineArgs.Add("--headless");
            Cef.Initialize(settings);

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            using (Form mainForm = new Form())
            {
                ChromiumWebBrowser browser = new ChromiumWebBrowser("https://www.example.com");
                mainForm.Controls.Add(browser);
                mainForm.Show();

                // Wait for the browser to initialize
                Application.DoEvents();

                // Load the JavaScript needed to interact with the browser
                browser.EvaluateScriptAsync("document.body.style.behavior = 'url(#default#homepage)'; document.body.style.expression = 'ieUseLinkHover=true';");

                // Wait for the page to load
                Application.DoEvents();

                // Add event handlers for navigation, loading, and error events
                browser.LoadingStateChanged += (sender, args) => { };
                browser.NavigationStateChanged += (sender, args) => { };
                browser.ErrorOccurred += (sender, args) => { };

                // Perform actions on the webpage using the browser object
                // ...

                // Close the browser when done
                browser.Dispose();
            }

            Cef.Shutdown();
        }
    }
}

To find elements using XPath, you can use the CefV8Handler class to execute JavaScript code that locates elements based on the XPath expression. Here's an example of how to find elements using XPath:

using System;
using CefSharp.WinForms;

namespace CefSharpXPathExample
{
    public class Program
    {
        [STAThread]
        public static void Main(string[] args)
        {
            CefSettings settings = new CefSettings();
            settings.BrowserSubprocessPath = "path/to/cef/browser_win32_x64.exe";
            settings.CefCommandLineArgs.Add("--disable-gpu");
            settings.CefCommandLineArgs.Add("--headless");
            Cef.Initialize(settings);

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            using (Form mainForm = new Form())
            {
                ChromiumWebBrowser browser = new ChromiumWebBrowser("https://www.example.com");
                mainForm.Controls.Add(browser);
                mainForm.Show();

                // Wait for the browser to initialize
                Application.DoEvents();

                // Load the JavaScript needed to interact with the browser
                browser.EvaluateScriptAsync("document.body.style.behavior = 'url(#default#homepage)'; document.body.style.expression = 'ieUseLinkHover=true';");

                // Wait for the page to load
                Application.DoEvents();

                // Execute JavaScript code to find elements using XPath
                browser.ExecuteScriptAsync("var xpath = arguments[0];" +
                                           "var result = document.evaluate(xpath, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null);" +
                                           "return result.singleNodeValue;", "//*[@id='element-id']");

                // Perform actions on the webpage using the browser object
                // ...

                // Close the browser when done
                browser.Dispose();
            }

            Cef.Shutdown();
        }
    }
}

In this example, we use the ExecuteScriptAsync() method to execute JavaScript code that finds elements using the provided XPath expression. The JavaScript code uses the document.evaluate() method to find the first matched node based on the provided XPath expression.

Keep in mind that the CefSharp library is actively maintained and provides a wide range of features for interacting with the browser. You can find more information and examples in the CefSharp GitHub repository.

In e-mail, proxy servers are used for secure data exchange as well as for collecting e-mails from several e-mail addresses at once. For example, this is how Gmail works, which also allows you to receive e-mails from mail.ru and other e-mail services.

This depends directly on how the proxy server works. Some of them do not require any authorization at all, others require username and password for access, and others require you to view ads and so on. Which option will be used depends directly on the service that provides access to the proxy server.

Most often it is used on the iPhone just to bypass the blocking of access to certain resources. But also VPN is one of the most effective methods of protecting your confidential information. After all, with VPN all traffic is additionally encrypted, the provider can't read it even if it's intercepted.
