Lopana Proxy

Free proxies, while seemingly profitable and attractive, are actually not very effective. They cannot boast of security, speed, stability and acceptable duration of work. Qualitative and reliable proxies require a certain investment, but they can be obtained from companies that have a good reputation as proxy service providers. You can also find out about all the nuances of proxy selection with the help of special proxy databases.

Connecting to a Selenium Hub via a corporate proxy can be challenging, as the proxy may require authentication or have specific settings that need to be configured. To connect to the Selenium Hub through a corporate proxy, you'll need to configure the proxy settings in your Selenium client and Hub.

Here's a step-by-step guide on how to set up a Selenium Hub and client with corporate proxy settings:

Configure the Selenium Hub:

First, you need to configure the Selenium Hub to use the corporate proxy. You can do this by modifying the Hub's configuration file (usually hub.yml or hub.json) and adding the proxy settings.

For example, if you're using the hub.yml file, add the following configuration:

proxy:
  type: http
  httpProxy: http://username:[email protected]:port
  nonProxyHosts: localhost, 127.0.0.1, .example.com

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy. The nonProxyHosts setting specifies a list of hosts that should not use the proxy.

Configure the Selenium client:

Next, configure the Selenium client to use the corporate proxy. You can do this by setting the proxy settings in your WebDriver configuration.

For example, in Python with the Chrome WebDriver, you can configure the proxy as follows:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.proxy import Proxy, ProxyType

proxy = Proxy()
proxy.proxy_type = ProxyType.MANUAL
proxy.http_proxy = "http://username:[email protected]:port"
proxy.ssl_proxy = "http://username:[email protected]:port"

chrome_options = Options()
chrome_options.add_argument("--proxy-server=%s" % proxy.proxy)

driver = webdriver.Chrome(options=chrome_options)
driver.get('your_url')

# Rest of your code

driver.quit()

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy.

Start the Selenium Hub and connect the client:

Start the Selenium Hub and connect the client to the Hub using the appropriate configuration settings.

For example, if you're using the hub.yml file, start the Hub with the following command:

selenium-server-standalone jar hub.yml

Connect the client to the Hub using the appropriate configuration settings. For example, in Python, you can connect the client to the Hub as follows:

from selenium import webdriver
from selenium.webdriver.remote.webdriver import WebDriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

desired_caps = DesiredCapabilities.CHROME
desired_caps['proxy'] = {
    'httpProxy': 'http://username:[email protected]:port',
    'ftpProxy': 'http://username:[email protected]:port',
}

driver = WebDriver(desired_caps=desired_caps)
driver.get('your_url')

# Rest of your code

driver.quit()

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy.

By following these steps, you should be able to connect to a Selenium Hub via a corporate proxy and use the Selenium client to interact with webpages.

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.

You cannot use a proxy server in Outlook (for security reasons). Therefore, it is possible to organize a local proxy with traffic forwarding through the port. Or you can use third-party tools such as ProxyCap.

Proxy "tunneling" should be understood as the isolation of traffic from the user. It allows you to form a fully protected channel for data exchange, which will be isolated from all other traffic.
