Nginx Reserve Proxy

Open the browser settings and go to the "Advanced" section. Click on "System" and then, in the window that opens, click on "Open proxy settings for computer". A window will appear in front of you, showing all the current settings. Another way to find out the http proxy is to download and install the SocialKit Proxy Checker utility on your computer.

The most convenient way is to use online proxy checkers, i.e. services that test all connection capabilities, including supported protocols. For example, Hidemy.name or Securitylab. As for applications, you can recommend SocksChain or Open Proxy Checker.

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 first thing to do is to find a suitable proxy server with an IP address and port. Then you should check whether the proxy works by means of a special program or an online service providing such services. The next step is to configure the type of browser you are going to use. The procedure of setting itself depends on the type of browser and does not take much time. After correctly entering the IP address, username and password of the proxy server, don't forget to save the changes you made.

In CentOS, if there is no graphical interface (from the terminal), proxy configuration is done through the export http_proxy=http://User:Pass@Proxy:Port/ command. Accordingly, User is the user, Pass is the password to identify you, Proxy is the IP address of the proxy, and Port is the port number. If you have DE, the configuration can be done via Network Manager (as in any other Linux distribution).
