It is an proxy frequently known as proxy server. It is a software that acts as an intermediary between client and server on the web. Without a proxy, a user could send a request for a resource directly to the server and it would deliver direct to users. It isn't difficult to understand and implement the use of proxy servers can offer advantages such as improved performance, privacy, security, and more. In addition to providing a layer of pass-through, they act as a gatekeeper on the internet between clients and servers.

The general entire set of hardware used by servers and the software to install proxy servers is commonly referred to by the name proxy servers. This article will concentrate on proxies that are typically thought of as software, and in relation to web servers. This article will give an explanation of the two types of proxies that include a forward proxy and reverse proxy. reverse proxy. Each has its own use scenario, which is often misunderstood due to the overlapping naming convention.

This article will provide you with an idea of the nature of proxies and subtypes, and how they function in normal configurations. Through the article you'll know what situations that using proxy servers is beneficial and how to choose the right option, based on forward and reverse proxy in each circumstance.

Understanding Forward Proxies

In the same way a forward proxy, also called an open proxy acts as the representative of a client who wants to send requests through the internet to an originating server. In this case the client's attempts to send requests by the client will be forwarded via the forward proxy. In this scenario the forward proxy acting instead of the client will review the request. The first step is to check if the client is authorized to receive requests from this specific forward proxy. It can then decide whether to deny the request or forward it to the original server. The client doesn't have a direct access to the internet; it can only access what the forward proxy permits it access to.

The most common reason to use forward proxies is to increase privacy or security online. A forward proxy uses the internet instead of a client, and in that process it could use an alternative IP address to the client's initial IP address.

Depending on how it's set up depending on how it's configured forward proxy can provide many options and the capability to:

• 
  
• 
  Beware of ad-tracker.
  
  
• 
  Circumvent surveillance.
  
  
• 
  Find restrictions based on your geographical location.
  
  

Forward proxies are also used in systems that offer centralized security and access based on permissions such as in the workplace. If all internet traffic is routed via an open forward proxy administrators could allow access only to specific users to the internet filtered through an ordinary firewall. Instead of having firewalls installed for the client layer which could include several devices that have different settings and users and settings A firewall could be set up at the forward proxy layer.

It is important to note that forward proxy servers must be manually set up for use to be utilized, whereas reverse proxy servers can be ignored by clients. Based on the fact that an IP address from the client is transferred to the origin server through the forward proxy privacy and anonymity can be provided or rendered transparent.

There are many options to explore for forward proxy options:

• 
  
• 
  Apache: A popular open-source webserver that provides forward proxy functionality.
  
  
• 
  Nginx: Another renowned open-source webserver that includes forward proxy functionality.
  
  
• 
  Squid: A free forward proxy based on the HTTP protocol. This doesn't offer the entire web server. You can check out our article on the best way to create Squid proxy to allow private connections within Ubuntu 20.04.
  
  
• 
  Dante Forward proxy that makes use of the SOCKS protocol instead of HTTP, making it better suitable for situations such as peer-to-peer connections. It's also a good idea to know how to setup an Dante proxy to connect privately using Ubuntu 20.04
  
  

Understanding Reverse Proxies

A reverse proxy functions to act as an agent of a web server, handling the incoming requests of customers on its behalf. The web server may be comprised of one server or a number of servers. Additionally, it can be used in the role of an application server, such as Gunicorn. In both cases, the request can originate from a user on the internet at large. In most cases, the request will be directly to the website server with the resources the client is in need of. In contrast, a reverse proxy works as an intermediary in order to protect your web server from interactions with the open internet.

From a client's perspective the experience of interacting with reverse proxy is not different from interacting with your webserver directly. It's basically identical and users cannot tell the distinction. The client requests a resource, and is then able to receive it with no additional configuration needed by the client.

Reverse proxies provide options like:

• 
  
• 
  Centralized security on webservers.
  
  
• 
  The sending of traffic in accordance with rules you create.
  
  
• 
  New caching functionality has been added.
  
  

While centralized security can be a benefit for both reverse and forward proxy platforms, reverse proxy provides this service to only the server layer, and not to the layer that clients use. In lieu of the maintenance of firewalls for the web server layer which may contain several servers with various configurations, the majority of firewall security may be centered to the reverse proxy layer. In addition, getting rid of the responsibility of interacting with firewalls and communicating with clients' requests away from web servers permits them to concentrate on addressing the needs of their clients.

If there are multiple servers behind a reverse proxy the reverse proxy is also responsible to control which requests are placed on which server. There could be multiple web servers providing the exact same service, serving different types of resources or a mixture of both. They can utilize the HTTP protocol as a conventional web server, but can also be equipped with application server protocols like FastCGI. A reverse proxy can be used to direct clients to specific servers based on the type of resource they're looking for, or to adhere to specific rules for traffic volume.

Reverse proxies may also take advantage of their location on top of web servers through the ability to cache data. The large static file can also be set up using caching rules to prevent hitting web servers on each request. Certain solutions allow you to serve static content directly without touching the server. In addition reverse proxy is capable of the compression of these assets.

The popular Nginx web server can be described as a powerful reverse proxy option. It is true that the Apache web server also comes with a reverse proxy feature, however, it's a separate attribute of Apache however Nginx was initially designed to and is focused specifically on the reverse proxy feature.

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

Since "forward" along with "reverse" can be interpreted as directionality and misleading comparisons with "incoming" and "outgoing" traffic. The labels are confusing because both kinds of proxies can handle both requests and responses. A better approach to differentiate between reverse as well as forward proxies would be to look at the specifications of the application that you're creating.

Reverse proxy is an important element to consider when designing a system that can provide web-based applications over the internet. They function as servers when you are connected to the internet.

A forward proxy is useful when it is placed in front of people for personal use, or even in a business environment. They represent your clients whenever you use the internet.

A case-based approach to distinction instead of focusing only on similar naming conventions can prevent confusion.

Conclusion

The article explained what a proxy is and the two kinds of them: forward and reverse proxy. Application scenarios that can be used in practical situations as well as an analysis of the most useful features were used to differentiate between forward and reverse proxy.
