AWS HTTP Proxy

"Work via VPN" means to connect to a site, an application or a remote server via a VPN server. That is, through an "intermediary" that not only hides the real IP address, but also additionally encrypts the traffic so that it cannot be "read".

The HTMLCleaner library is typically used for cleaning and transforming HTML documents, but it does not provide a direct API for parsing HTML. Instead, it's often used in conjunction with an HTML parser to clean and format the HTML content.

Here's an example using HTMLCleaner along with the Jsoup library, which is a popular HTML parser in Java

Add the HTMLCleaner and Jsoup dependencies to your project. You can use Maven or Gradle to include them.

For Maven:

    net.sourceforge.htmlcleaner
    htmlcleaner
    2.25



    org.jsoup
    jsoup
    1.14.3

For Gradle:

implementation 'net.sourceforge.htmlcleaner:htmlcleaner:2.25'
implementation 'org.jsoup:jsoup:1.14.3'

Use HTMLCleaner and Jsoup to parse and clean HTML:

import org.htmlcleaner.CleanerProperties;
import org.htmlcleaner.HtmlCleaner;
import org.htmlcleaner.TagNode;
import org.htmlcleaner.XPatherException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

public class HtmlParsingExample {
    public static void main(String[] args) {
        String htmlContent = "
Hello, world!
";

        // Parse HTML using Jsoup
        Document document = Jsoup.parse(htmlContent);

        // Clean the parsed HTML using HTMLCleaner
        TagNode tagNode = cleanHtml(document.outerHtml());

        // Perform additional operations with the cleaned HTML
        // For example, extracting text content using XPath
        try {
            Object[] result = tagNode.evaluateXPath("//body/p");
            if (result.length > 0) {
                TagNode paragraph = (TagNode) result[0];
                String textContent = paragraph.getText().toString();
                System.out.println("Text content: " + textContent);
            }
        } catch (XPatherException e) {
            e.printStackTrace();
        }
    }

    private static TagNode cleanHtml(String html) {
        HtmlCleaner cleaner = new HtmlCleaner();
        CleanerProperties properties = cleaner.getProperties();

        // Configure cleaner properties if needed
        properties.setOmitXmlDeclaration(true);

        try {
            return cleaner.clean(html);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}

In this example, Jsoup is used for initial HTML parsing, and HTMLCleaner is used to clean the HTML. You can perform additional operations on the cleaned HTML, such as using XPath to extract specific elements.

The tool that exists to run Selenium tests in headless mode is called "Headless Browsers". Headless browsers are browser automation tools that run without a graphical user interface (GUI). They are typically used for testing web applications without the need for a visible browser window. Some popular headless browsers include:

1. Chrome's Headless mode: Chrome's headless mode can be enabled by passing the --headless flag when launching a ChromeDriver instance.

2. Firefox's Headless mode: Firefox's headless mode can be enabled by passing the --headless flag when launching a GeckoDriver instance.

3. PhantomJS: PhantomJS is a headless browser that can be used with Selenium to run tests without a visible browser window.

4. Puppeteer: Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It can be used to run tests in headless mode.

5. HtmlUnit: HtmlUnit is a headless browser that can be used with Selenium to run tests without a visible browser window.

It's important to note that the specific implementation of running Selenium tests in headless mode may vary depending on the browser and the version of the Selenium WebDriver being used.

To enable a proxy on your computer, you'll need to configure the proxy settings for your operating system and web browser. Here's a general guide for Windows and macOS, along with instructions for popular web browsers:

For Windows:

1. Press Win + I to open the Settings app.
2. Click on "Network & Internet."
3. On the left sidebar, click on "Proxy."
4. Select "Manual proxy setup" and enter the proxy server's IP address and port number. If your proxy requires a username and password, enter those as well.
5. Click "Save" or "Apply" to enable the proxy.

For macOS:

1. Open "System Preferences."
2. Click on "Network."
3. Select the network connection you want to configure (e.g., Wi-Fi or Ethernet).
4. Click on the "Proxy" tab.
5. Choose "Automatic Proxy Configuration," "Manual Proxy Configuration," or "No Proxy" based on your needs.
6. If you choose "Manual Proxy Configuration," enter the proxy server's IP address and port number. If your proxy requires a username and password, enter those as well.

Click "OK" or "Apply" to enable the proxy.

A firewall is responsible for filtering packets of traffic. For example, it blocks access to the Internet for certain applications. There are many more options for using a proxy. But if you install special software, it can also be used for such purposes.
