It is an proxy commonly called proxy server. It is a software that sits as an intermediary between the client and server on the internet. Without a proxy, a user could send a request for a resource directly to the server and it would then serve that resource to its user directly. It's not hard to understand and implement the proxy feature can provide advantages like improved performance and privacy, security and many more. As a further layer of security, proxies act as a gatekeeper on the internet, separating clients and servers.

In general, the collection of server hardware along with the software for proxy installation is usually referred to in the context of proxy servers. This article will concentrate on proxies commonly referred to as software, and also in the context of web servers. The article will offer an explanation of the two types of proxies that include a forward proxy and reverse proxy. reverse proxy. Each has its own use situation, and is frequently confused because of the similar the name convention.

This article will provide you with an idea of the types of proxies, their subtypes, and how they work in common configurations. In the article you'll be able to understand how to identify the circumstances in which using proxy servers is beneficial and how to choose the best option between reverse and forward proxy, in each circumstance.

Understanding Forward Proxies

In other words, a forward proxy sometimes called an open proxy acts as the representative of a customer who would like to make requests over on the web to an original server. In this scenario any requests sent by the client will instead be transferred to the forward proxy. In this situation, the forward proxy instead that of the user will review the request. It is the first thing to check if the client is authorised to receive requests from this particular forward proxy. It can then decide whether to deny an request and forward it to its original server. The client does not have direct connection to the internet but it is able to connect to the internet that the forward proxy allows the client to access.

The primary reason for people to use forward proxies is to gain greater privacy or security on the internet. A forward proxy utilizes the internet in lieu of a client and in that process it could use an alternative IP address from that of the client's original IP address.

Based on the way it's setup, and how it's configured forward proxy could provide various options and the capability to:

• 
  
• 
  Beware of ad-tracker.
  
  
• 
  Circumvent surveillance.
  
  
• 
  Find limitations based on the geographic area.
  
  

Forward proxies are also used in systems that offer centralized security and access based on user permissions, for example, in the workplace. If all internet traffic flows via an open forward proxy an administrator could grant access only to specific users to the internet through an ordinary firewall. Instead of putting firewalls on the client layer which may contain multiple devices with different settings and users and environments A firewall could be set up at the forward proxy layer.

It is important to note that forward proxy servers have to be manually configured for use to be utilized, whereas reverse proxy servers can be not recognized by clients. Depending on whether an IP address from the user is transferred to the origin server through the forward proxy privacy and anonymity may be granted or made more transparent.

There are many possibilities to consider to find forward proxy options

• 
  
• 
  Apache is a well-known open-source web server, which offers forward proxy functionality.
  
  
• 
  Nginx: Another renowned open-source webserver that has forward proxy functionality.
  
  
• 
  Squid: A free forward proxy using the HTTP protocol. This doesn't offer the entire web server. You can check out our guide on the best method of creating Squid proxy to permit private connections within Ubuntu 20.04.
  
  
• 
  Dante Forward proxy that makes use of the SOCKS protocol instead of HTTP which makes it more suited for scenarios such as peer-to-peer traffic. It is also possible to learn how to configure the Dante proxy to connect privately on Ubuntu 20.04
  
  

Understanding Reverse Proxies

A reverse proxy functions to act as an agent of web servers, which handles any requests that come in from customers on behalf of the server. The web server may consist of a single server or even multiple servers. In addition, it could serve in the role of an application server like Gunicorn. In either scenario the request may be made by a client via the web in general. In most cases, the request will be directly to the website server with the resources that the customer needs. Instead, a reverse proxy functions as an intermediary that isolates your server from interaction with the open internet.

From a customer's point of view, the experience when using reverse proxy is not different from communicating directly with your webserver. It's basically identical and users cannot tell the distinction. The client requests a resource, and then receives it, without any additional configuration by the client.

Reverse proxies provide options like:

• 
  
• 
  Centralized security on webservers.
  
  
• 
  Sending traffic to be directed according to rules you can make.
  
  
• 
  New caching functionality has been added.
  
  

While central security is an advantage of both reverse and forward proxy platforms, reverse proxy provides this service to only the server layer, and not to the client layer. In lieu of the maintenance of firewalls on Web server layers that could include multiple servers with different configurations, the bulk of firewall security can be concentrated on the reverse proxy layer. Additionally eliminating the hassle of connecting to a firewall as well as dealing with requests from clients far from web servers permits them to concentrate on meeting the requirements of their clients.

In the case of multiple servers running in a reverse proxy, the reverse proxy also is responsible for deciding which requests go on which server. There could be multiple web servers offering the same service, but serving different kinds of resources or a mixture of both. They can utilize the HTTP protocol just like a standard web server, but they can also be equipped with protocols for application servers like FastCGI. A reverse proxy to send clients to particular servers based on the type of resource they are looking for, or to adhere to specific rules for traffic load.

Reverse proxies may also benefit from their location on top of web servers by offering the capability to store information. Massive static content can be set up using caching policies to stop hitting web servers on each request. Certain solutions allow you to deliver static content directly without touching the web server in any way. In addition reverse proxy has the capability of the compression of these assets.

The well-known Nginx web server can be described as a powerful reverse proxy service. While it's real that Apache web server is also equipped with a reverse proxy feature, however, it's a separate attribute of Apache but Nginx was initially designed for and focuses specifically on the reverse proxy feature.

Differentiating Forward Proxy from Reverse Proxy Use. and Reverse Proxy Use

Since "forward" in addition to "reverse" are associated with directionality and misleading comparisons with "incoming" as well as "outgoing" traffic. These labels can be confusing because both types of proxies are able to handle requests and also respond. A better approach to distinguish between reverse proxy and forward proxy is to look at the specifications of the application that you are developing.

Reverse proxy is an essential feature when designing a solution that allows web-based applications via the internet. They function as servers whenever you connect to the internet.

A forward proxy is beneficial when it is placed in front of individuals for personal use or even in a business environment. They represent your clients when you interact with the internet.

The use case-based differentiation instead of focusing solely on similar naming conventions can help avoid confusion.

Conclusion

The article described what a proxy is as well as the two types of them being the forward and reverse proxy. Examples of practical application scenarios as well as an examination of useful features was utilized to differentiate between forward and reverse proxy.
