Friends, you must have heard about proxy server many times or have read about the word proxy server in internet or any tech books or if you are using internet in a company, then you must have seen that by not getting proxy not responding error Comes and the internet doesn't run. If seen, the proxy server is mostly used by the company. But have you ever thought that what is this proxy server and why is it used, what are the advantages of using it. If you also want to know a lot about proxy server, then read this post carefully.
What is a proxy server?
Before understanding the proxy server, let us understand the word proxy, what is the meaning of proxy. You will remember that when we used to study in school or college, when we were late, we used to tell our friend to install my proxy.
What I mean to say is that proxy means to represent the other as your friend in class is doing to you.
The proxy server acts as a means of connecting you to the Internet. It is an intermediary server that separates users from the websites they browse. Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, requirements, or company policy. If you are using a proxy server, Internet traffic goes through the proxy server to the address you requested. The request then returns via the same proxy server (there are exceptions to this rule), and then the proxy server forwards the data you receive from the website.
Modern proxy servers do much more than forward web requests, all in the name of data security and network performance. Proxy servers act as a firewall and web filter, providing cached data to speed up shared network connections and common requests. A good proxy server protects users and internal networks from bad stuff. Finally, proxy servers can provide a high level of privacy.

Types of proxy servers
There are two main types of proxy servers.
Forward Proxies
A forward proxy, or gateway, or just "proxy" provides proxy services to a client or group of clients. There are likely to be hundreds of thousands of open forward proxies on the Internet. They store and forward Internet services (like DNS, or web pages) to reduce and control the bandwidth used by a group.
Forward proxies Sometimes proxy servers are anonymous and allow users to hide their IP address while browsing the web to maintain their privacy or use other internet services. TOR (The Onion Router) routes Internet traffic through multiple proxies for anonymity.
Reverse Proxies
As the name suggests, reverse proxy is the opposite of one forward proxies: a forward proxy works on behalf of the client (or requests from hosts ), the reverse proxy works on behalf of the server. Forward proxies can hide the identities of clients while reverse proxies can hide the identities of servers. There are many use cases behind reverse proxies, such as:
Load balance: Distributes load to many web servers .
Cache static content : Close the web server by caching static content like images,
Compression: Compresses the content to speed up and improve download time.
Advantages of using proxy server
The advantages of using a proxy server are as follows:
Monitoring and filtering
Improve performance
translation
Accessing Services Anonymously
Security
Monitoring and filtering
Proxy servers allow us to perform many types of filtering such as:
Content Filtering
Filtering encrypted data
Bypass filter
Logging and eavesdropping
Improve performance
This accelerates service by the process of retrieving content from the cache that was saved by the client at the time of the previous request.
Translation
This helps to optimize the source site for local users by dropping the original content or replacing the source content with local content. In this, traffic of global users is sent to the source website through a translation proxy.

Accessing Services Anonymously
In this, the destination server receives a request from the unoning proxy server and thus does not get information about the end user.
Security
Since the proxy server hides the identity of the user, it protects against spam and hacker attacks.
