Ums 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.

Automapper is a library primarily used for mapping data between objects in C# applications. It is not specifically designed for parsing XML, but you can use it in conjunction with other libraries, such as XmlDocument or XDocument, to map XML data to C# objects.

Here's a simple example of parsing XML using XDocument and Automapper:

Assuming you have the following XML structure:

  John
  Doe

And a corresponding C# class:

public class PersonDto
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

You can use Automapper to map the XML data to your C# object:

using AutoMapper;
using System;
using System.Xml.Linq;

class Program
{
    static void Main()
    {
        // XML data
        string xmlData = "JohnDoe";

        // Parse XML using XDocument
        XDocument xmlDoc = XDocument.Parse(xmlData);

        // Configure Automapper
        MapperConfiguration config = new MapperConfiguration(cfg =>
        {
            cfg.CreateMap()
                .ForMember(dest => dest.FirstName, opt => opt.MapFrom(src => src.Element("FirstName").Value))
                .ForMember(dest => dest.LastName, opt => opt.MapFrom(src => src.Element("LastName").Value));
        });

        IMapper mapper = config.CreateMapper();

        // Map XML to C# object
        PersonDto personDto = mapper.Map(xmlDoc.Root);

        // Print the result
        Console.WriteLine($"FirstName: {personDto.FirstName}");
        Console.WriteLine($"LastName: {personDto.LastName}");
    }
}

In this example, we use Automapper's CreateMap method to define a mapping between XElement and PersonDto. The ForMember method is used to specify how each property of PersonDto should be mapped from the corresponding XML element.

Keep in mind that Automapper may be more beneficial when dealing with complex object mappings rather than simple XML parsing scenarios. For straightforward XML parsing tasks, using XDocument or XmlDocument directly might be sufficient.

To add a custom method to a Selenium module, you can extend the existing Selenium class and add your method to the subclass. Here's an example in Python using Selenium WebDriver

Let's say you want to add a custom method named custom_method to the WebElement class in Selenium:

from selenium.webdriver.remote.webelement import WebElement

# Define your custom method
def custom_method(self, arg1, arg2):
    # Your custom logic here
    print(f"Custom Method: {arg1}, {arg2}")

# Add the custom method to the WebElement class
WebElement.custom_method = custom_method

# Now, you can use the custom method on any WebElement instance
driver = webdriver.Chrome()
element = driver.find_element(By.XPATH, "//input[@name='username']")
element.custom_method("arg1_value", "arg2_value")

In this example:

1. We import the WebElement class from selenium.webdriver.remote.webelement.
2. We define a custom method custom_method that takes two arguments (arg1 and arg2) and prints a message.
3. We add the custom method to the WebElement class by assigning it as an attribute (WebElement.custom_method).
4. We create a WebDriver instance and find a WebElement on the page using a locator (e.g., By.XPATH).
5. We call the custom method on the WebElement instance, passing the desired arguments.

This approach allows you to extend Selenium's classes with your custom methods. Keep in mind that modifying the core Selenium classes may have consequences, and you should be careful not to override existing methods or cause conflicts with future updates.

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.

In data centers, proxies are used to provide IP to virtual servers. After all, one server there can be used by a dozen users at the same time. And each needs to be allocated its own IP and port. All this is done through proxies.
