Yes, it is possible to use Selenium without opening a visible browser window by using headless mode. Headless mode allows the browser to run in the background without displaying the graphical user interface. This can be useful for running automated tests or web scraping processes without the overhead of a visible browser.

Here's an example of how to use headless mode with Selenium in Python:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# Create ChromeOptions and set headless mode
chrome_options = Options()
chrome_options.add_argument('--headless')

# Create WebDriver instance with headless mode
driver = webdriver.Chrome(options=chrome_options)

# Your Selenium script...

# Close the browser when done
driver.quit()

In this example:

chrome_options.add_argument('--headless') is used to enable headless mode for Chrome.

You can apply a similar approach for other browsers like Firefox:

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

# Create FirefoxOptions and set headless mode
firefox_options = Options()
firefox_options.headless = True

# Create WebDriver instance with headless mode
driver = webdriver.Firefox(options=firefox_options)

# Your Selenium script...

# Close the browser when done
driver.quit()

Headless mode is beneficial for scenarios where you don't need to visually inspect the browser while the script is running, and it can also help in improving the performance of your automated processes. Keep in mind that certain actions, especially those related to rendering and interaction with the visible browser, may behave differently in headless mode.

Using UDP, you can request data from a server by sending a request message to the server. Since UDP is a connectionless protocol, you need to know the server's IP address and port to send the request. The server should have a predefined mechanism to handle incoming requests and return the desired data as a response.

Here's a high-level overview of how to request data from a server using UDP:

1. Prepare your request message: Create a message containing the data you want to request from the server. The format of the message depends on the specific application and data you're working with.

2. Send the request message to the server: Use a UDP socket to send the request message to the server's IP address and port. The server should be listening for incoming UDP packets on that address and port.

3. Receive the response from the server: The server processes the incoming request and sends back a response. Use a UDP socket to receive the response on the same or a different port, depending on the application's requirements.

4. Process the response: Extract the desired data from the response and process it as needed.

Here's an example using Python:

import socket

# Prepare the request message
request_message = b"REQUEST_DATA"

# Create a UDP socket
client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# Send the request message to the server
server_address = ('127.0.0.1', 12345)
client_socket.sendto(request_message, server_address)

# Receive the response from the server
response_message, server_address = client_socket.recvfrom(1024)

# Process the response
print(f"Received response: {response_message}")

# Close the socket
client_socket.close()

In this example, the sendto() function sends a request message to the server, and the recvfrom() function receives the response from the server. The server should be running and listening for incoming UDP packets on the specified address and port.

The main task of these two popular technologies is to provide security for the Internet user. Despite a certain similarity of tasks, they are performed absolutely differently. Proxy, although it allows you to remain anonymous and bypass blocked sites, it is still quite vulnerable, especially when it comes to untested services. VPN in this regard looks preferable, because thanks to end-to-end encryption it reliably protects information from the entry point to the exit point.

In Android to disable the proxy, you need to go to "Settings", then - "Connection and sharing", then - to "VPN". And then just deactivate the item. Many phones also provide for automatic disabling of proxies and VPNs when the device is rebooted. That is, if the user is difficult to understand the settings of the gadget, then you can trivially restart it through a long press the lock button (forced reboot).

It means routing traffic from multiple devices through a single proxy server. In this way you can, for example, organize a local network in an office environment, but where all the traffic data can be viewed from the administrator's server.
