Cash Proxy

It means a proxy that has no access to the Internet. It is created using special software on the user's computer. Most often it is used to check the performance of the created site or web-application.

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 Simple HTML DOM Parser is a PHP library that allows you to manipulate HTML content easily. Below is an example of how to use the Simple HTML DOM Parser to parse and extract information from an HTML document.

First, make sure you have the Simple HTML DOM Parser library included in your project. You can download it from the official repository on GitHub.

Include the library in your PHP file:

include('path/to/simple_html_dom.php');

Use the library to parse and extract information from an HTML document:

// Example HTML content
$htmlContent = '
Hello, world!
';

// Create a Simple HTML DOM object
$html = str_get_html($htmlContent);

// Extract text content from a specific element
$textContent = $html->find('div.container p', 0)->plaintext;

// Output the result
echo "Text Content: $textContent";

In this example:

The str_get_html function is used to create a Simple HTML DOM object from the HTML content.

The find method is used to locate a specific element (div.container p) in the HTML.

The plaintext property is used to extract the text content of the found element.

Make sure to replace 'path/to/simple_html_dom.php' with the actual path to the Simple HTML DOM Parser library.

You can perform various operations with Simple HTML DOM Parser, such as finding elements by tag, class, or ID, traversing the DOM tree, and extracting attributes. Refer to the official documentation for more details and examples.

To test a UDP sender, you can create a mock UDP client that simulates the behavior of the real UDP client. This way, you can test the sending functionality without actually sending data over the network.

Here's an example of how to create a mock UDP client and write a unit test for a UDP sender in C#:

1. Create a mock UDP client class:

public class MockUdpClient : IDisposable
{
    private readonly byte[] _receivedBytes;
    private int _receivedCount;

    public MockUdpClient()
    {
        _receivedBytes = new byte[1024];
        _receivedCount = 0;
    }

    public void Receive(byte[] data, int length)
    {
        Array.Copy(data, _receivedBytes, length);
        _receivedCount++;
    }

    public void Dispose()
    {
        // Clean up any resources if needed
    }

    public int ReceivedCount => _receivedCount;

    public byte[] ReceivedData => _receivedBytes;
}

2. Modify the UDP sender to accept a mock UDP client:

public class UdpSender
{
    private readonly MockUdpClient _mockUdpClient;

    public UdpSender(MockUdpClient mockUdpClient)
    {
        _mockUdpClient = mockUdpClient;
    }

    public void SendData(string data)
    {
        var bytes = Encoding.ASCII.GetBytes(data);
        _mockUdpClient.Receive(bytes, bytes.Length);
    }
}

3. Write a unit test for the UDP sender:

[TestClass]
public class UdpSenderTests
{
    [TestMethod]
    public void TestSendData()
    {
        // Arrange
        var mockUdpClient = new MockUdpClient();
        var udpSender = new UdpSender(mockUdpClient);
        var data = "Test data";

        // Act
        udpSender.SendData(data);

        // Assert
        Assert.AreEqual(1, mockUdpClient.ReceivedCount);
        CollectionAssert.AreEqual(Encoding.ASCII.GetBytes(data), mockUdpClient.ReceivedData);
    }
}

In this example, we created a MockUdpClient class that simulates the behavior of a real UDP client. The UdpSender class now accepts a MockUdpClient as a parameter, allowing us to test the sending functionality without actually sending data over the network.

Finally, we wrote a unit test using the TestClass and TestMethod attributes from the Microsoft.VisualStudio.TestTools.UnitTesting namespace. The test method TestSendData checks whether the UdpSender class sends data correctly by comparing the received data with the expected data.

Open the "Browser Properties" in the control panel, in the "Connections" section of the opened window select "Network Settings". Remove the check mark from the "Use proxy" item, click "OK".
