Why Node servers need reverse proxies

Sitting there under a sycamore tree late at night with a light breeze, I couldn't help but get caught up in thinking about why Node servers need reverse proxies. Like a difficult puzzle, it fascinates me.

The wonders of Node proxy servers

The story begins a long, long time ago, in this distant and magical world of the Internet, in which countless information flows every day, like a raging river with a thousand sails. However, it is because of such a raging tide that communication with each other has become extremely complicated. Those brave and wise developers, then came up with a magic weapon - proxy servers.

Like a little wizard, the Node proxy server sits at the center with endless wisdom and power. When you visit a certain website, it will ask the target server for you, get the required data, and deliver this valuable information to you. It's as if you're picking up ipipgo on the beach and the proxy server is the dedication of countless waves.

But why do we still need reverse proxies? This question used to bother me for a long time, until one day a vivid analogy came to me.

Let's say you're a famous painter and everyone aspires to own your artwork. Your studio is a Node server that displays a variety of stunningly famous paintings. However, these famous paintings are not displayed directly in front of the store, but through a mysterious door, the reverse proxy server, for visitors to enjoy.

Why is that? Because your studio is tucked away in a secluded alley, and the only way in is through this door. People outside the door don't know where your studio is; they can simply stand in the doorway, give it a push, and touch the beauty of your art.

However, this door is not just a simple medium. Behind it lies a myriad of hidden mechanisms and protections that filter out malicious access and hacking, protecting your precious artwork from the elements.

It's like an unexpected hero appeared in front of me, this reverse proxy server to the traditional front-end and back-end perfect combination of silent for us to create a myriad of convenience.

The wonders of reverse proxies

In this virtual world of legends, reverse proxy servers are not just for protecting your studio, there are many other wonderful uses.

A common scenario is load balancing. Like a magic balance, a reverse proxy server can intelligently distribute requests to multiple back-end servers based on the load of the current request, allowing each server to reach its full potential. It's like a fruit party where every fruit is fully savored and no fruit is left out in the cold.

Another important feature is caching. In life, we often encounter repetitive tasks, such as that stretch of road on your way to work every day where you always take the same path. A reverse proxy server is like a smart navigation system that will memorize that stretch of road for you, and next time simply repeat the journey without having to ask for directions again.

最后，反向代理服务器还能提供更高的安全性。它可以屏蔽真实的后端服务器信息，保护服务器的IP地址和端口等敏感数据，使得黑客无法直接攻击到后端服务器。就好像是一道牢不可破的城，守护着你的财富和安全。

concluding remarks

Standing in this magical and imaginative world of the Internet, we deeply feel the importance of why Node servers are reverse proxied. It is like a musician at a live concert, working silently with each instrument to create a beautiful melody.

Let's enjoy this symphony and feel the convenience and security that reverse proxies bring. Let's witness the magic of Node proxy servers in this colorful chapter!
