SFTP Reverse Proxy

To assign a proxy server to an Android or iOS access point, follow these steps:

Open the "Settings" section. Go to the "Wi-Fi" tab. Select your access point. Click on "Proxy". Use manual setup and specify the data of proxy. Save the settings.

A web proxy is a web application that is installed on a web server. It acts as an intermediary for downloading certain content from various websites. The user gets the opportunity, thanks to the web proxy, to remain anonymous while downloading all kinds of web resources. Web proxies are good for such tasks as speeding up the loading of websites, providing anonymous access to websites, bypassing restrictions and gaining access to closed websites.

To scrape images in C#, you can use the HTMLAgilityPack library for parsing HTML and retrieving image URLs. Here's a basic example

Install HTMLAgilityPack

You can install the HTMLAgilityPack NuGet package using the following command in the Package Manager Console:

Install-Package HtmlAgilityPack

Write a C# script to scrape images:

using System;
using System.Collections.Generic;
using HtmlAgilityPack;

class Program
{
    static void Main()
    {
        string url = "https://example.com"; // Replace with the URL of the page you want to scrape images from

        // Download HTML content from the URL
        HtmlWeb web = new HtmlWeb();
        HtmlDocument document = web.Load(url);

        // Extract image URLs
        List imageUrls = ExtractImageUrls(document, url);

        // Print the extracted image URLs
        foreach (string imageUrl in imageUrls)
        {
            Console.WriteLine(imageUrl);
        }
    }

    static List ExtractImageUrls(HtmlDocument document, string baseUrl)
    {
        List imageUrls = new List();

        // Select image elements using XPath
        var imageElements = document.DocumentNode.SelectNodes("//img[@src]");

        if (imageElements != null)
        {
            foreach (var imageElement in imageElements)
            {
                // Extract image URL from the src attribute
                string imageUrl = imageElement.GetAttributeValue("src", "");

                // Make the URL absolute if it's a relative URL
                imageUrl = new Uri(new Uri(baseUrl), imageUrl).AbsoluteUri;

                // Add the URL to the list
                imageUrls.Add(imageUrl);
            }
        }

        return imageUrls;
    }
}

This script uses HTMLAgilityPack to load the HTML content of a webpage and extract image URLs using XPath. The ExtractImageUrls method selects image elements with the XPath query "//img[@src]", retrieves the src attribute, and converts relative URLs to absolute URLs.

Run the script:

Replace the url variable with the URL of the webpage you want to scrape images from.

Run the script to see the list of image URLs.

If Selenium doesn't see the driver from Selenium.WebDriver.ChromeDriver, it could be due to a few reasons. Here are some steps to troubleshoot and resolve the issue:

Check the ChromeDriver version:

Make sure you're using the correct version of ChromeDriver that matches the version of the Chrome browser installed on your system. You can download the appropriate version of ChromeDriver from here.

Update the ChromeDriver path:

Ensure that the path to the ChromeDriver executable is correctly specified in your code. If you're using the ChromeOptions class to set the path, make sure you're using the correct property name. For example, in C#, use the ExecutablePath property:

ChromeOptions options = new ChromeOptions();
options.AddArgument("--headless");
options.ExecutablePath = @"C:\path\to\chromedriver.exe";

using (ChromeDriver driver = new ChromeDriver(options))
{
    driver.Navigate().GoToUrl("your_url");
    // Rest of your code
}

Replace C:\path\to\chromedriver.exe with the actual path to the ChromeDriver executable on your system.

1. Check for multiple ChromeDriver versions:

Sometimes, having multiple versions of ChromeDriver installed on your system can cause issues. Make sure there are no conflicting versions of ChromeDriver on your system and that the correct version is being used.

2. Check for antivirus or security software interference:

Sometimes, antivirus or security software can interfere with the execution of ChromeDriver. Try temporarily disabling your antivirus or security software to see if it resolves the issue. If it does, you may need to add an exception for ChromeDriver or change your antivirus settings.

3. Check the console output:

Examine the console output for any error messages or warnings that might provide more information about the issue. This can help you identify the root cause of the problem and find a suitable solution.

If you've tried all these steps and are still encountering issues, please provide more information about your system, including the operating system, Chrome browser version, and the specific error message or problem you're facing. This will help diagnose the issue further and find a suitable solution.

If you are interested in a quality and fast proxy server, do not look for it among the free options. All of them, although they seem to be profitable, in fact do not differ in duration of work and speed. It is recommended to buy quality proxies from reputable proxy service providers that are widely available on the Internet.
