Proxy Sek

To configure a proxy on your MikroTik router, you need the Winbox software. The following steps must be done in the application: Open the "IP"-"WebProxy" sections. Check the box next to "Enabled". Enter the parameters of the proxy-server.

After that you have to specify the data of the proxy in the browser to be used. As an example, let's take Google Chrome. What you need to do:

Open the browser.
Click on the icon "?" in the upper right corner.
Go to "Settings".
Select the "Advanced" option.
Click the "System" tab.
Click on "Open proxy settings for your computer".
Click on "Network settings".
Activate the "Use proxy server" option.
In the tab that opens, specify the IP address of the proxy server. You should enter it in the field of the protocol to which the proxy server belongs.
Click the "OK" button to save your settings.

If you are parsing a site using JSoup in a Java application and you want to introduce a delay between requests to avoid being blocked or rate-limited by the website, you can use Thread.sleep to pause the execution for a specified duration. Here's a basic example

First, make sure you have the JSoup library included in your project. If you're using Maven, you can add the following dependency to your pom.xml:

    org.jsoup
    jsoup
    1.14.3 

Now, here's an example Java program using JSoup with a delay between requests:

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

import java.io.IOException;

public class WebScraperWithDelay {

    public static void main(String[] args) {
        // Replace with the URL you want to scrape
        String url = "https://example.com";
        
        // Number of milliseconds to wait between requests
        long delayMillis = 2000; // 2 seconds
        
        try {
            for (int i = 0; i < 5; i++) {
                // Make the HTTP request using JSoup
                Document document = Jsoup.connect(url).get();

                // Process the document as needed
                System.out.println("Title: " + document.title());

                // Introduce a delay between requests
                Thread.sleep(delayMillis);
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

In this example:

1. Jsoup.connect(url).get() is used to make an HTTP request and retrieve the HTML document from the specified URL.
2. Thread.sleep(delayMillis) introduces a delay of 2 seconds between requests. You can adjust the value of delayMillis based on your needs.

To simulate manual text input in Selenium WebDriver, you can use the send_keys method to send a sequence of keys to an input field. Here's an example of how to do this in Python:

Install the required package:

pip install selenium

Create a method to simulate manual text input:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

def simulate_manual_text_input(driver, locator, text_to_send):
    element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located(locator))
    element.clear()
    element.send_keys(text_to_send)

Use the simulate_manual_text_input method in your test code:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Set up the WebDriver
driver = webdriver.Chrome()
driver.maximize_window()

# Navigate to the target web page
driver.get("https://www.example.com")

# Locate the input field
locator = (By.ID, "username")

# Simulate manual text input
simulate_manual_text_input(driver, locator, "your_username")

# Perform any additional actions as needed

# Close the browser
driver.quit()

In this example, we first create a method called simulate_manual_text_input that takes a driver instance, a locator tuple containing the locator strategy and locator value, and a text_to_send string containing the text to send to the input field. Inside the method, we use the WebDriverWait class to wait for the element to become visible and then clear the input field and send the text using the send_keys method.

In the test code, we set up the WebDriver, navigate to the target web page, and locate the input field using the locator variable. We then call the simulate_manual_text_input method with the driver, locator, and "your_username" as input. After simulating the manual text input, you can perform any additional actions as needed.

Remember to replace "https://www.example.com", "username", and "your_username" with the actual URL, input field ID or name, and the text you want to type into the input field.

To check if your proxy is working, you can perform a simple test by accessing a website through the proxy. Here's a step-by-step guide:

1. Open your web browser and navigate to a website that you can use to test your proxy connection. Websites like "http://www.whatismyip.com/" or "https://www.proxy-check.org/" are commonly used for this purpose.

2. If you're using a proxy server, you'll need to configure your browser or a proxy extension to use the proxy. You can usually find this setting in your browser's network settings or under the proxy settings.

3. Enter the proxy server address (IP address or hostname) and port number in the appropriate fields in your browser or proxy extension settings.

4. Save your changes and refresh the web page with the test site.

5. If the proxy is working correctly, the website should display your proxy's IP address or a different IP address than your original one. This indicates that the proxy is successfully routing your traffic.

6. If the website displays your original IP address, it means that the proxy is not working or not being used.

A proxy in data centers is usually a separate server that processes incoming requests and then distributes them to the submitted addresses (or IP). Also through the proxy it is possible to allocate a specific user a separate IP address for connection (for example, if he needs a virtual server).
