When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers

| Recently I have reading Effective Java and the following really | |
| took me some time to digest as it seems easy but tricky. | |
| Sample code is as the following: | |
| (!Attention: for simplicity, hashCode is not given here) | |
| ``` | |
| public class EqualsTest { | |
| public class Point { | |
| private int _x; | |
| private int _y; |
