To check if a port is available over UDP, you can try binding to the port for a short period. If the binding is successful, the port is available. If it fails, the port is already in use. Here's a simple example in Python:

import socket

def is_port_available(port, host='127.0.0.1', timeout=2):
    with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as sock:
        try:
            sock.bind((host, port))
            sock.settimeout(timeout)
            return True
        except OSError:
            return False
        finally:
            sock.close()

if __name__ == "__main__":
    port = 12345
    if is_port_available(port):
        print(f"Port {port} is available.")
    else:
        print(f"Port {port} is not available.")

In this example, the is_port_available function creates a UDP socket and attempts to bind to the specified port and host. If the binding is successful, the function returns True, indicating that the port is available. If the binding fails, the function returns False, indicating that the port is already in use.

In JavaScript with Selenium, you can save and reuse cookies using the WebDriver's manage().getCookies() and manage().addCookie() methods. Here's a simple example:

const { Builder } = require('selenium-webdriver');
const firefox = require('selenium-webdriver/firefox');

// Create a new instance of the Firefox driver
const driver = new Builder()
  .forBrowser('firefox')
  .setFirefoxOptions(new firefox.Options().headless())
  .build();

// Navigate to a webpage
async function navigateToPage() {
  await driver.get('https://example.com');
}

// Save cookies
async function saveCookies() {
  const cookies = await driver.manage().getCookies();
  // Save the cookies to a file or some storage mechanism
  // For simplicity, we'll just print them here
  console.log('Cookies:', cookies);
}

// Reuse cookies
async function reuseCookies(savedCookies) {
  // Delete existing cookies
  await driver.manage().deleteAllCookies();

  // Add the saved cookies to the browser session
  for (const cookie of savedCookies) {
    await driver.manage().addCookie(cookie);
  }

  // Navigate to a page to apply the cookies
  await navigateToPage();
}

// Example usage
(async () => {
  await navigateToPage(); // Navigate to the page and set some initial cookies

  await saveCookies(); // Save the cookies

  // Close and reopen the browser or navigate to a different page
  // ...

  // Reuse the saved cookies
  await reuseCookies(savedCookies);
})();

The navigateToPage function navigates to a webpage and sets some initial cookies.

The saveCookies function retrieves the current cookies using manage().getCookies() and prints them. You would typically save them to a file or some storage mechanism.

The reuseCookies function deletes existing cookies, then adds the saved cookies back to the browser session using manage().addCookie(). It then navigates to a page to apply the cookies.

The example usage section demonstrates how to use these functions in a sequence.

Before activating a proxy server in Opera, it is recommended that you clear your browsing history and cookies of sites. This is necessary to ensure that information about the computer is not transmitted during further connections. To do this, it is enough to follow the algorithm:

Open the browser.
Click on the opera icon in the upper left corner.
Hover your mouse cursor over the "History" item.
Use the option "Clear history of visits".
After that you need to specify parameters of the proxy server. To do this, perform the following actions:

Open your browser.
Click on the Opera icon in the top left corner.
Click on "Settings".
Select the "Advanced" option.
Scroll down to the "System" tab.
Click on "Open proxy settings for computer".
Click on "Network settings".
Activate the "Use a proxy server" option.
In the window that opens, specify the IP address of the proxy server. Enter the address in the field of the protocol to which the proxy server belongs. You can get this information from your provider.
Click "OK" to save your settings.

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".

Audience parsing is the collection of information about users. Most often it is used to get statistical data, to check the server capacity. Sometimes it is also used to compile a database of potential customers.
