Wildfly Proxy

In Windows, proxy settings for local connections are made through the "Network and Sharing Center" (from the "Control Panel"). You need to select "Browser Properties", then go to "Connections" and click on "Network Setting". And there you can set either the script or the parameters for the proxy.

Jsoup is a Java library for working with HTML documents. To scrape links using Jsoup, you can use its selector syntax to target the anchor elements and then extract the href attributes. Here's a simple example:

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import java.io.IOException;

public class LinkScraper {
    public static void main(String[] args) {
        String url = "https://example.com";

        try {
            // Connect to the website and get the HTML document
            Document document = Jsoup.connect(url).get();

            // Select all anchor elements
            Elements links = document.select("a");

            // Iterate over each anchor element and print the href attribute
            for (Element link : links) {
                String href = link.attr("href");
                System.out.println("Link: " + href);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Make sure to replace the url variable with the URL of the website you want to scrape.

This example connects to the specified URL, retrieves the HTML document, selects all anchor elements using the "a" selector, and then iterates over them to print the href attributes.

You need to include the Jsoup library in your project. If you are using Maven, you can add the following dependency to your pom.xml:

    org.jsoup
    jsoup
    1.14.3 

You can check it with the ping command from the command line in Windows. It is enough to enter it, with a space - the data of the proxy server (including the number of the port used) and press Enter. The reply message will tell you whether or not you have received a reply from the remote server. If not, the proxy is unavailable, respectively.

It means that now all the traffic is sent to a VPN server (which can be an ordinary proxy). This is a kind of warning that the remote server can now collect data. Therefore, you should use only well-tested VPN services.

The easiest way to do this is to use online proxy checking services. For example, Hidemy Name. It is free, displays technical data about the connection, and at the same time it also checks the ping.
