Tomcat Proxy Server

There are 2 ways to do this. The first is to manually change the settings in /etc/environment, but you will definitely need root access to do that. You can also use the Network Manager utility (compatible with all common DEs). You just have to make sure beforehand that the driver for the network adapter to work properly is installed on the system.

After authorization in Selenium, you can navigate to another page using the get() method. The following steps outline the process:

Here's an example using Python:

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

driver = webdriver.Chrome()
driver.get("https://www.example.com/login")

# Locate the username field, password field, and login button
username_field = driver.find_element(By.ID, "username")
password_field = driver.find_element(By.ID, "password")
login_button = driver.find_element(By.ID, "login-button")

# Input your username and password
username_field.send_keys("your_username")
password_field.send_keys("your_password")

# Click the login button
login_button.click()

# Wait for the page to load after authorization
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "post-login-button")))

# Navigate to another page
driver.get("https://www.example.com/new-page")

In this example, replace "https://www.example.com/login", "username", "password", "login-button", and "your_username", "your_password" with the actual values for the website you are working with. Also, replace "https://www.example.com/new-page" with the URL of the page you want to navigate to after authorization.

Note that the example uses explicit waits to wait for the page to load after authorization. This is a good practice to ensure that the next actions are performed only after the page is fully loaded.

To know the type of proxy, you need to identify the communication protocol it uses. Proxies can be categorized based on the protocol they support, such as HTTP, HTTPS, SOCKS, or other specific protocols. Here's how to determine the type of proxy you are using or working with:

1. Check the proxy settings: If you are using a proxy on your device or within an application, examine the proxy settings to see which protocol is specified. For example, the settings might indicate "HTTP Proxy," "HTTPS Proxy," or "SOCKS Proxy."

2. Observe the proxy URL: The proxy URL can sometimes indicate the type of proxy. For example, an HTTP proxy URL usually starts with "http://" or "https://" followed by the proxy server's IP address or hostname, while a SOCKS proxy URL typically starts with "socks://" followed by the proxy server's IP address or hostname.

3. Analyze the proxy server's behavior: You can also determine the type of proxy by observing how it handles incoming and outgoing requests. For instance, an HTTP proxy will typically forward HTTP and HTTPS requests, while a SOCKS proxy can handle any type of traffic, including non-HTTP protocols.

4. Use online tools or software: There are various online tools and software applications that can help you identify the type of proxy. By connecting to the proxy server and analyzing the traffic, these tools can often determine the protocol used by the proxy.

5. Consult the proxy provider: If you are unsure about the type of proxy you are using, you can always consult the proxy provider or the documentation that came with the proxy server. They should be able to provide you with the necessary information about the proxy type.

To connect to the Internet via a proxy server, you need to configure your browser or operating system to use the proxy server. Here's a general guide for setting up a proxy server using a web browser:

1. Open your web browser.

2. Access the browser settings or preferences:
- On Windows: Click the three-dot menu in the top-right corner and select "Settings."
- On macOS: Click the Apple menu in the top-left corner, select "System Preferences," and click "Network."
- On Linux: Click the menu button in the top-right corner, select "Settings," and click "Network."
- On Android: Open the "Settings" app and tap "Network & internet."
- On iOS: Open the "Settings" app and tap "Wi-Fi."

3. Locate the proxy settings:
- On Windows: Under "Network," click "Proxy settings."
- On macOS: Click the "Advanced" button and go to the "Proxies" tab.
- On Linux: Click the "+" button to add a new proxy.
- On Android: Tap "Private DNS" and "Static IP address" under "Advanced options."
- On iOS: Tap "Configure Proxy" under the active Wi-Fi network.

4. Enter the proxy server address, port, and authentication details (if required):
- Proxy server address: Enter the domain name or IP address of the proxy server (e.g., http://proxy-server).
- Port: Enter the port number used by the proxy server (e.g., 8080).
- Username and Password (optional): If the proxy server requires authentication, enter the username and password provided by the proxy server provider.

5. Save the proxy settings and restart the browser.

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.
