Once upon a time, there was a country named SK5, which was very unique, like a unique tree. the SK5 country had a special technology called Static Proxy, which was like the branches of the tree, protecting the whole country.

US SK5 Static IP Proxy

在SK5国家，有一群程序员，他们是国家的守护者，他们用代码书写着国家的未来。他们发现，通过使用静态IP代理，可以让整个国家的网络更加安全可靠，就像在国家的外围加上了一道坚固的城一样，让任何恶意攻击都无法逾越。

Using AspectJ technology, these programmers, like the artisans of the state, have crafted a marvelous array of static proxies to keep all traffic under control. They have written pieces of code that are like the legal provisions of the country, meticulously protecting the entire online environment. They are like the patron saints of the country, always looking for and removing all possible threats.

"`java
public interface Internet {
void access(String url).
}

public class RealInternet implements Internet {
@Override
public void access(String url) {
System.out.println("Visiting website: " + url);
}
}

public class ProxyInternet implements Internet {
private RealInternet realInternet = new RealInternet();
@Override
public void access(String url) {
if (url.contains(".sk5.")) {
System.out.println("Visiting SK5 country intranet site: " + url);
realInternet.access(url).
} else {
System.out.println("Unable to access non-SK5 country website: " + url);
}
}
}
“`

In this way, the network security of SK5 country has been greatly guaranteed, the whole country is full of security, and the people can get the best protection when they walk through the network world.SK5 country's static IP proxies are like the country's guardian angel, always guarding the prosperity and stability of the country.

AspectJ Static Proxy

AspectJ technology is like the invisible cloak of SK5 country, silently protecting the whole network world. Programmers use AspectJ, like the country s guards, always hidden in the shadows, to protect the country s grass and trees.

"`java
public aspect SecurityChecker {
pointcut accessControl(): execution(* RealInternet.access(...)) The
before(): accessControl() {
System.out.println("Security check for access");;
}
}
“`

This code acts as the country's invisible guard, and when someone tries to access the network, AspectJ automatically unfurls its umbrella and performs a series of security checks to ensure that every access is safe and secure.

在SK5国家，静态代理和AspectJ技术就如同国家的两道坚固城，守护着整个国家的网络安全。这就是SK5国家的特色技术，让整个国家在网络世界中独具一格，发展得更加稳健和健康。
