Expert Shield Proxy

You can avoid fraud related to the use of your proxy by using special online services. Proxy-checkers are focused on recognizing any proxy format, its degree of uniqueness and anonymity, speed, as well as a number of other important parameters.

A DNS server is a remote computer that receives a domain request from a user device. And it converts it into an IP address. Sometimes it is through the DNS-server that ISPs block sites. And DNS-proxy, respectively, allows you to bypass these restrictions completely.

Qt primarily focuses on providing tools and libraries for GUI development, networking, and other application-level features. While it includes facilities for working with XML through classes like QXmlStreamReader and QXmlStreamWriter, these are more geared toward parsing XML rather than HTML.

For HTML parsing, especially when using XPath expressions, you might need to consider additional libraries or tools. One common choice is to use a third-party library like Gumbo or htmlcxx. These libraries are not part of the Qt framework, but they can be used alongside Qt to handle HTML parsing.

Here's a basic example using htmlcxx for HTML parsing:

#include 
#include 
#include 

int main(int argc, char *argv[]) {
    QCoreApplication a(argc, argv);

    std::string htmlData = "
Hello, world!
";

    htmlcxx::HTML::ParserDom parser;
    tree dom = parser.parseTree(htmlData);

    // Example XPath query
    std::string xpathExpression = "//p/span";
    std::vector::iterator> result;
    htmlcxx::XPath::NodeSet nodeSet;
    htmlcxx::XPath::Parser xpathParser;
    xpathParser.compile(xpathExpression.c_str(), &nodeSet);

    for (tree::iterator it = dom.begin(); it != dom.end(); ++it) {
        nodeSet.evaluate(*it);
        if (nodeSet.size() > 0) {
            result.push_back(it);
        }
    }

    // Output the result
    for (auto &it : result) {
        std::cout << "Match found: " << htmlcxx::HTML::toPlainText(it->begin(), it->end()) << std::endl;
    }

    return a.exec();
}

In this example, I've used htmlcxx for HTML parsing and XPath queries. Note that you need to include the htmlcxx library in your project.

An access point (AP) is a device that creates a wireless local area network (WLAN) and allows devices to connect to a wired network. Proxy settings on an access point refer to the configuration of the AP to use a proxy server for internet traffic.

A proxy on an access point serves the following purposes:

1. Anonymity: By routing internet traffic through a proxy server, the AP can help conceal the identity and location of devices connected to the network. This can be useful in situations where anonymity is desired or required.

2. Content filtering: A proxy server can be configured to block or allow access to specific websites or content based on predefined rules. This can be helpful for organizations that want to control and monitor the internet usage of their users.

3. Bandwidth management: Using a proxy server, an access point can limit or prioritize the bandwidth for specific applications or users. This can help manage network resources and ensure fair usage.

4. Caching: Proxy servers can cache frequently accessed content, reducing the amount of data that needs to be downloaded from the internet. This can improve performance and reduce bandwidth usage.

A proxy is a service that allows access to websites blocked in different countries, while hiding your own IP address. It is a kind of intermediary between the end server and the owner's computer. A VPN provides an encrypted connection to the network, which not only allows you to keep your privacy, hide your IP address, encrypt Internet traffic, but also bypasses firewalls.
