Web Proxy Server (What does Web Proxy Server mean)

Hey, friends! Today, I want to talk to you about web proxy servers. You might be wondering, what exactly does web proxy server mean? Well, let me explain it to you in plain language.

Fatty and his courier agent

Imagine we have a boy named Fatty who lives in an apartment with an intricate mix of upstairs and downstairs. However, Humpty Dumpty's laziness makes him reluctant to go downstairs to collect his deliveries himself. So, he finds a reliable delivery agent and entrusts him to help him receive his packages.

Well, a web proxy server is like a little fat courier agent. It acts as an intermediary between the user and the Internet, helping us process network requests, fetch data, and transmit messages.

Code example: simulating a web proxy server

“`
function fetchWebsiteData(url) {
// Send the request to a web proxy server
const proxyServer = 'http://www.proxyserver.com';
const requestData = {
url: url,
method: 'GET'
};
const responseData = sendRequest(proxyServer, requestData);
// Processing the returned data
// …
return processedData.
}
“`

The three main roles of web proxy servers

Next, let's dive into the three main roles of web proxy servers.

1. Hide the real IP address

A web proxy server is like a mask that helps us hide our real IP address. It will send requests and receive responses instead of us, making it impossible for the outside world to track our real identity. It's as if Little Fatty is helped by a proxy, and the courier package doesn't arrive at his address directly, but first arrives at the proxy's hands.

2. Provision of cache

Web proxy servers also provide caching, which is like Little Fatty's agent having a special warehouse for commonly used courier packages. When Humpty Dumpty needs the same package a second time, the agent can take it out of the warehouse directly, saving time and effort.

3. Filtering and interception of requests

Finally, a web proxy server can also filter and block requests. It can help us block unwanted content, block malware and protect our privacy, just like the little fat agent who carefully checks every courier package to make sure no dangerous items enter.
