Proxy Server Explanation and Functions

Proxy Server Explanation and Functions

Oops, you've come to the right person! Today let me as an old programmer to give you an explanation of the mystery of the proxy server and the wonderful use of it. Do not look at its name is quite lofty, in fact, it is a "transfer station", like a flexible courier, to help you send the packet to the destination.

What is a proxy server?

Well, Proxy Server (Proxy Server) is that silent and dedicated gadget that exists like a hidden bridge that connects you to the gateway to the online world. To put it simply, it is a service that delivers messages between you and the web server. If you want to visit a certain website, your request is not sent directly to the target site, but first to the proxy server, and then it will help you forward to the target site.

What are the features of a proxy server?

Without further ado, let's see what a proxy server can do for you. Hey guys, get ready, I'm going to show you how it's done!

1. Hide the real IP address

Hmmmm, this is the best trick of proxy servers! You know, there are times when we don't want others to know our real identity on the internet, such as wanting to see the website we are on, hahaha! At this time, you can find a proxy server, let it help us hide the real IP address, others can not track us.

ipipgothon
import requests
Setting up a proxy server
proxy = {
"http": "http://127.0.0.1:8888",
"https": "http://127.0.0.1:8888"
}
Send the request
response = requests.get("https://example.com", proxies=proxy)
Output the response
print(response.text)

2. Access to blocked websites

This is my favorite feature! There are times when certain websites are blocked and we want to access them but we can't, and that's when proxy servers come in handy. Through a proxy server, we can bypass the blocking, and happily access the blocked site.

ipipgothon
import requests
Setting up a proxy server
proxy = {
"http": "http://127.0.0.1:8888",
"https": "http://127.0.0.1:8888"
}
Send the request
response = requests.get("https://example.com", proxies=proxy)
Output the response
print(response.text)

3. Accelerated access

You must have come across the problem of slow access to certain websites, right? Sometimes it's because the web server is too far away, sometimes it's because the server is under pressure. At this time, the proxy server can help you a hand, it can cache the content of the web pages that have been visited, the next time you visit the same web page, directly from the cache to fetch the data, eliminating the time to request the server again, so that your Internet experience faster and smoother!

ipipgothon
import requests
Setting up a proxy server
proxy = {
"http": "http://127.0.0.1:8888",
"https": "http://127.0.0.1:8888"
}
Send the request
response = requests.get("https://example.com", proxies=proxy)
Output the response
print(response.text)

concluding remarks

Wow, after reading this article, do you have a deeper understanding of proxy servers? It is not only a "transit station", but also can hide the IP address, access to blocked sites, accelerate the speed of access, is simply a universal tool! Remember what I said, to use a good proxy server, open a pleasant journey online oh!
