Proxy server
Before reading the proxy server, we understand what a proxy is?
Proxy means "to present someone else or to act on behalf of someone else." In other words, "make any indirect service available."

Similarly, a proxy server can also be a computer system or application that acts as an intermediate for the client and the client's request goes through this intermediate server.
And the server also conveys the request to the client through the same intermediate.
In other words, "proxy server is a computer that acts like the gateway between the user's computer and the internet.

The proxy server is also called the application level gateway.
Through this, the client computer can establish an indirect network connection from other networks.

Let us briefly understand how does this work?

As you can see in the picture, we have a client, proxy server and a web server. Suppose a client wants to open a website, then they will request the proxy server to open the website. And the proxy server will send the client's request to the web server. Now the web server will open the website and give it to the proxy server. Because the web server has been sent by the request proxy server. And then the proxy server will give the service of that website to the client.

proxy server benefits: -
1: - This is used for caching i.e. when a client accesses any information, then it saves information when another client accesses the same information from the same cache in the same client as the client Gives to This increases the speed of the internet so that time is saved.
2: - This hides the IP address, that is, it does not know the identity of the client. Whichever information goes to the Internet, it belongs to the proxy server. By which our network becomes secure. Because those hackers who are attackers do not know that the actual request received has come from said.
3: - This can block the website, that is, if the client does not want to use any website, then it can block it by it.
4: By this, the client can also open the blocked websites ie you must have noticed that some websites in our office or in the college such as: - social media sites or dirty sites are not open. Because they have been blocked. So we can also open these websites through the proxy server. This is exactly the opposite of point 3.

types of proxy server: -
The following types are: -
1: -anonymous proxy
2: - SSL proxy
3: - transparent proxy
4: - reverse proxy

1: - anonymous proxy: - This proxy provides privacy to the client, meaning that it hides the client's IP address. So that no person like Hacker etc can trace the client's location.

2: - SSL proxy: - SSL (secure socket layer) is used in any online transaction. Just as if you bought any stuff from amazon, their site has an SSL proxy that protects our data online during purchase. The website that has https before the url is the same SSL
3: - transparent proxy: - In this proxy the request is forwarded to the Internet through the client's server. But the client's information is not hidden in it. It is also called forward proxy.
4: - reverse proxy: - This proxy is used to access requests from client to client server.
