The word "proxy" refers to a proxy also referred to a proxy server a server software that acts in the role of an intermediary a client and server on the internet. Without the use of a proxy, a user would make a request resources directly to a server, then the server could provide the resource directly back to the user. Although this method is easy to grasp and use but adding proxies offers advantages such as enhanced performance, privacy, security, and many more. As a further layer of pass-through, the proxy acts as a security safeguard for the internet between servers and clients.

Generally speaking, the bundled system of server hardware with proxy software installed is sometimes referred to as proxy servers. This article will focus on the types of proxies that are typically thought as software, and specifically with regard to web servers. The article will provide a description of the two major kinds that are available, including a forward proxy and the other a reverse proxy. reverse proxy. Each type has a different use case, often confused due to the overlapping terminology.

This article will provide the understanding of the different types of proxies, which subtypes they belong to and how they function in a variety of configurations. In this guide, you'll be able to identify situations in which the use of proxies is advantageous, and decide on the right choice between forward proxy and reverse proxy, in any scenario.

Understanding Forward Proxies

The forward proxy also referred to an open proxy serves as an intermediary to allow a user to make a request via the internet to an source server. In this case, the entire process of sending requests from the user is made via the forward proxy. Forward proxy that acts as a substitute as the customer, is able to examine into the request. It will decide whether this client can accept requests via this particular forward proxy. Then, it will either reject requests or redirect them to the original server. The client isn't capable of having an internet connection directly. It is only able to access what forward proxy allows the client to connect.

A common use case of forward proxy is to achieve more privacy or security when using the internet. Forward proxy connects to the internet using the user and it could use a different IP address that is different to the initial IP address of the client.

Based on how it's been configured in accordance with the way it was configured forward proxy can provide a variety of functions and permit you to:

• 
  
• 
  Avoid tracking ads.
  
  
• 
  Circumvent surveillance.
  
  
• 
  Find limitations based on your location.
  
  

Forward proxies also are used in systems that rely on central security and access based on permissions, like in workplaces. If all traffic on the internet flows through an open forward proxy layer an administrator can grant access to only a few people to connect on the internet. This is then filtered by a standard firewall. Instead of creating firewalls on the layer of clients, which can be used by several computer systems with different configurations and users and environments, a firewall may be set up at this layer to forward proxy data.

It is essential to note that forward proxies must be configured manually and reverse proxies could be ignored by the client. Depending on the type the IP address that a user is transmitted to the server from which it was received through the forward proxy Privacy and anonymity could be granted or not.

There are many possibilities to look into for forward proxy:

• 
  
• 
  Apache An open-source, well-known web server that provides forward proxy capabilities.
  
  
• 
  Nginx: Another well-known open-source server for web hosting with forward proxy capabilities.
  
  
• 
  Squid is an open-source forward proxy using the HTTP protocol. It's not the entire Web Server System. We have a step-by-step guide on how to installing Squid proxy to allow private connections within Ubuntu 20.04.
  
  
• 
  Dante Forward Proxy which uses the SOCKS protocol instead of HTTP this makes it more appropriate for situations like peer-topeer traffic. It is also possible to learn how to setup a Dante proxy for private connections in Ubuntu 20.04
  
  

Understanding Reverse Proxies

A reverse proxy functions as an intermediary between a web server that handles any requests that come in from customers on behalf of the server. This server can function as a single server or multiple servers. Furthermore, it could serve as an application server, such as Gunicorn. In any event the request will be made through the internet in general. Typically, the request will go directly to the server with what the client is seeking. The reverse proxy acts as an intermediary, securing the server from direct contact via the web's public.

From a user's point of perspective, the experience of working with reverse proxy isn't a lot different than working with the server itself. It's the same, but the client can't discern the difference. The client can request the resource and is provided with it, without any additional configuration required from the client.

Reverse proxy providers offer services such as:

• 
  
• 
  Security centralized for web servers.
  
  
• 
  Traffic coming into your site is routed by rules you have set.
  
  
• 
  The caching feature was added to the application.
  
  

While central security is a benefit of both reverse and forward proxy services, reverse proxy providers this feature at the layer of web servers but not to the client layer. instead of the maintenance of firewalls on Web server layers which may contain multiple servers with different configurations, most of firewall security can be concentrated at the reverse proxy layer. Additionally, getting rid of the responsibility of working with firewalls as well as interacting with requests from clients outside of web servers lets them concentrate on the needs of their clients.

If there are multiple servers running in a reverse proxy, the reverse proxy takes care of directing which requests go to which server. There could be multiple web servers providing the exact identical service, but each providing different types of resource or a mixture of both. They could use the HTTP protocol to function as a traditional web server. But, they may also be using application server protocols such as FastCGI. You can configure a reverse proxy to direct visitors to specific server depending on the service they require, or to follow specific rules for traffic load.

Reverse proxies are also able to gain advantage from their position ahead of web servers, providing the ability to cache data. Massive static resources can be managed by caching rules so that they avoid the web server from being hit on every request. Certain software solutions let you offer static files directly without connecting to the web server in any way. Furthermore, the reverse proxy could handle the compression of these assets.

The well-known Nginx web server also serves as an efficient reverse proxy option. You can also use the Apache web server as reverse proxy capabilities, it is an additional option for Apache and Nginx was designed originally for and is focused specifically on reverse proxy features.

The distinction between Forward and Reverse Proxy Use The Case

Because "forward" and "reverse" are associated with directionality, as well as false connections with "incoming" as well as "outgoing" traffic the labels could be confusing because both kinds of proxy are capable of handling both requests and responses. Another method of separating between reverse and forward proxy is to look at the specifications of the application you're creating.

A reverse proxy can be useful when building a solution to serve web-based applications via the internet. They are your web servers for all interactions over the internet.

Forward proxy is useful when placed in front of customers for your personal use or within the corporate setting. It is a way to protect the information of your client every time you use the internet.

Differentiating by case of use instead of focusing on common naming conventions can assist you in avoiding confusion.

Conclusion

The article explained the purpose of a proxy having two kinds: the forward proxy and reverse proxy. Practical use cases and an analysis of beneficial characteristics were used to determine the two kinds of proxy: forward and reverse. If you're keen to know more about the possibilities of proxies then we suggest you read our guide on how you can configure Nginx for use as a web server and reverse proxy on Apache using an Ubuntu 20.04 server.
