Parsing is the collection of all information. Accordingly, parsing a site is copying all of its source code as presented. You can use it to edit the site further or to analyze it for security purposes.

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.

A browser configured for the HTTP protocol sends client requests not directly, but through a proxy server, which in turn sends them on its own behalf to the destination host. The proxy server here acts as a link between the computer and the requested resource, and the response it immediately sends to the client.

Under such parsing we mean the collection of keywords from services such as Yandex Wordstat. These data will later be required for SEO-promotion of the site. The resulting word combinations are then integrated into the content of the resource, which improves its position in SERPs on a particular topic.

Technically, ISP can block only some intermediary servers by IP-addresses. But it's impossible to block absolutely all VPN-servers, because there are so many of them and their addresses are constantly changing. Accordingly, in this case, you just need to use another VPN-server.
