4DO Proxy

You need to open the settings menu, go to "Data and disk", and then - "Proxy settings". There you can enter the address, port number of the intermediate server, as well as username and password for authorization (if necessary).

Popup scraping typically involves interacting with web pages that have dynamic content, including popups or modals. To scrape data from popups, you may need to use a headless browser automation library. One popular choice is Selenium, which provides a WebDriver API for interacting with browsers.

Here's an example using Python and Selenium to scrape data from a webpage with a popup

Install Selenium:

pip install selenium

• Download WebDriver:

  • Download the WebDriver for the browser you want to use. In this example, I'll use ChromeDriver. Download it from ChromeDriver Downloads and place the executable in your project directory or in a directory listed in your system's PATH.

• Write the Scraping 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

def scrape_with_popup(url):
    # Set up the WebDriver (make sure the WebDriver executable is in the same directory or in your PATH)
    driver = webdriver.Chrome()

    try:
        # Open the webpage
        driver.get(url)

        # Locate and click the button/link that triggers the popup
        popup_trigger = driver.find_element(By.ID, 'popup-trigger')
        popup_trigger.click()

        # Wait for the popup to appear (adjust the timeout as needed)
        WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, 'popup-content')))

        # Extract data from the popup
        popup_content = driver.find_element(By.ID, 'popup-content').text
        print("Popup Content:", popup_content)

    finally:
        # Close the browser window
        driver.quit()

# Replace 'https://example.com' with the actual URL of the webpage
scrape_with_popup('https://example.com')

3. • Replace 'https://example.com' with the actual URL of the webpage you want to scrape.
   • Replace 'popup-trigger' and 'popup-content' with the actual IDs or other locators of the elements triggering the popup and the popup content.

4. Run the Code:

   • Execute the Python script, and it will open a browser, interact with the webpage, and print the content of the popup.

This example assumes that the webpage you are working with uses a trigger element (button/link) to open the popup.

In UDP communication, there is no built-in mechanism to confirm if the client has received data from the server. UDP is a connectionless protocol, which means it does not establish a connection between the client and server, and therefore, it does not provide any reliability guarantees.

However, there are some techniques you can use to improve the reliability of UDP communication and get an indication that the client has received data:

1. Acknowledgment packets: The server can send acknowledgment packets after sending data to the client. The client can then send acknowledgment packets back to the server after receiving the data. If the server does not receive the acknowledgment packets within a specific timeout period, it can assume that the client has not received the data.

2. Timeout and retransmission: The server can implement a timeout and retransmission mechanism. If the server does not receive an acknowledgment packet within a specific timeout period, it can resend the data and continue to do so until it receives an acknowledgment or reaches a predefined limit.

3. Checksums or hashes: The server can send data along with a checksum or hash value. The client can then calculate the checksum or hash of the received data and compare it with the value sent by the server. If the values match, the client can be confident that it has received the data correctly.

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.
