Bellesa Proxy

To deactivate the proxy server on Windows 10, you need to perform the following steps:
Open the "Windows Settings" menu.
Go to the "Network and Internet" tab.
Open the "Proxy Server" section.
Deactivate the "Use setup script" option.
Deactivate "Use proxy server" option. Reboot your computer. If the proxy server option has not been disabled, deactivate the "Define parameters automatically" option in the "Proxy server" section. After that you have to restart your PC again.

To scrape an image using Selenium in C#, you can find the image element on the web page and then retrieve the image source (URL) or download the image file. Here's a simple example:

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

class Program
{
    static void Main()
    {
        // Set up the Chrome WebDriver
        using (var driver = new ChromeDriver())
        {
            // Navigate to the web page containing the image
            driver.Navigate().GoToUrl("https://example.com");

            // Find the image element (replace with your actual locator)
            IWebElement imageElement = driver.FindElement(By.XPath("//img[@id='your_image_id']"));

            // Get the source URL of the image
            string imageUrl = imageElement.GetAttribute("src");

            Console.WriteLine("Image Source URL: " + imageUrl);

            // Download the image (optional)
            DownloadImage(imageUrl);
        }
    }

    // Function to download the image
    static void DownloadImage(string imageUrl)
    {
        using (var webClient = new System.Net.WebClient())
        {
            // Replace "downloaded_image.jpg" with your desired file name
            webClient.DownloadFile(imageUrl, "downloaded_image.jpg");
            Console.WriteLine("Image Downloaded Successfully.");
        }
    }
}

In this example:

The Chrome WebDriver is set up.

The program navigates to a web page (replace "https://example.com" with the actual URL).

The image element is located using a locator (replace "//img[@id='your_image_id']" with the actual XPath or other locator for your image).

The source URL of the image is retrieved using GetAttribute("src").

Optionally, the DownloadImage function is called to download the image using WebClient. Adjust the file name and path as needed.

In Scrapy, you can control the caching behavior of requests made by rules in your spider by adjusting the dont_cache attribute in the Rule object. The dont_cache attribute, when set to True, indicates that the requests matched by the rule should not be cached.

Here's an example of how you can use dont_cache in a CrawlSpider:

from scrapy.linkextractors import LinkExtractor
from scrapy.spiders import CrawlSpider, Rule

class MySpider(CrawlSpider):
    name = 'my_spider'
    allowed_domains = ['example.com']
    start_urls = ['http://example.com']

    rules = (
        # Example Rule with dont_cache set to True
        Rule(LinkExtractor(allow=('/page/')), callback='parse_page', follow=True, dont_cache=True),
    )

    def parse_page(self, response):
        # Your parsing logic for individual pages goes here
        pass

- The spider is defined as a CrawlSpider.
- The Rule is created with LinkExtractor to match URLs that contain '/page/' in them.
- The dont_cache=True attribute is set to True in the Rule, indicating that requests matched by this rule should not be cached.

By setting dont_cache to True, Scrapy will make sure that requests matched by this rule will be fetched without considering the cache. This is useful when you want to ensure that each request to the specified URLs results in a fresh response, bypassing any cached data.

An "open" proxy means one that is publicly available. It can be used by many network users at the same time. But because of this its bandwidth is also quite low, because the server simultaneously handles all requests through a single port.

Before activating a proxy server in Opera, it is recommended that you clear your browsing history and cookies of sites. This is necessary to ensure that information about the computer is not transmitted during further connections. To do this, it is enough to follow the algorithm:

Open the browser.
Click on the opera icon in the upper left corner.
Hover your mouse cursor over the "History" item.
Use the option "Clear history of visits".
After that you need to specify parameters of the proxy server. To do this, perform the following actions:

Open your browser.
Click on the Opera icon in the top left corner.
Click on "Settings".
Select the "Advanced" option.
Scroll down to the "System" tab.
Click on "Open proxy settings for computer".
Click on "Network settings".
Activate the "Use a proxy server" option.
In the window that opens, specify the IP address of the proxy server. Enter the address in the field of the protocol to which the proxy server belongs. You can get this information from your provider.
Click "OK" to save your settings.
