"proxy" is a term used to describe a server "proxy" is a reference to the fact that a proxy or proxy server. It is software that acts in the middle between client and a server on the internet. Without the proxy, the client could make a request for a service directly to the server and it would then serve the requested resource directly back to the user. It is easy to comprehend and implement, using proxies can provide benefits in the form of increased security, performance, privacy as well as many other benefits. As a layer of pass-through, proxy servers act as a gatekeeper on the internet between servers and clients.

In general, the combination of server hardware and the software that is installed to make proxy connections is often called proxy servers. But, this article will focus on proxy servers which are typically described in terms of software and ones that work in conjunction with web servers. The article will provide a description of two types of proxy servers, specifically the forward proxy and reverse proxy. reverse proxy. Each kind has its own terminology that could be confusing because of the overlap in terminology.

This article will provide you with an idea of the nature of proxies and their subtypes and their value in the typical setups. If you read this article, you will be able to discern the scenarios where an effective proxy is beneficial, and determine the most suitable choice between forward proxy and reverse proxy in any circumstance.

Understanding Forward Proxies

In other words, a forward proxy sometimes referred to as an open proxy is an agent of an individual user trying to make an online request to an server. In this situation every attempt to send requests by the client will rather be directed by this forward proxy. In this case the forward proxy acting in the client's stead, will look into the request. At the beginning it will decide if it is allowed to send requests to this particular forward proxy. Then, it can either reject requests or redirect it to its origin server. The client doesn't have a direct connection to the internet It has access only to what the forward proxy allows the client to access.

The most popular reason for using forward proxy servers is to provide more privacy or security online. Forward proxy accesses the internet on behalf of the individual client. And in this way, it may utilize an IP address different from the original IP of the user.

Based on the way it's setup depending on the way it's set up, forward proxy could offer a range of functions as well as the capability of:

• 
  
• 
  Beware of Ad-trackers.
  
  
• 
  Circumvent surveillance.
  
  
• 
  You will be able to identify any restrictions based upon your location.
  
  

Forward proxies also are utilized in systems that provide central security, as well as access granted on a permission basis, like, in a workplace. When all traffic on the internet flows through an open forward proxy layer, administrators may restrict only a small number of users online access which is then filtered by a common firewall. Instead of establishing firewalls for clients, that can be utilized by multiple computers with various configurations and users and environments, a firewall can be put in this forward proxy layer.

Be aware that forward proxy servers must be manually setup before they can be used while reverse proxy servers could be ignored by clients. Based on whether or not the IP address of the client is sent to the origin server through the forward proxy, privacy and anonymity could be granted or kept secret.

There are a myriad of possibilities to think about when it comes to forward proxy options.

• 
  
• 
  Apache The Apache is a popular open-source web server, which provides forward proxy capabilities.
  
  
• 
  Nginx: Another popular open-source web server with forward proxy capabilities.
  
  
• 
  Squid is an open source forward proxy that uses an HTTP protocol. It doesn't provide the full web server system. Check out our guide on the most efficient method of installing Squid proxy for private connections for Ubuntu 20.04. Ubuntu 20.04.
  
  
• 
  Dante forward proxy, which uses using the SOCKS protocol, instead of HTTP this makes it better suited for scenarios such as peer-to-peer traffic. It is also possible to look into how to set up Dante proxy to allow connection to private networks in Ubuntu 20.04
  
  

Understanding Reverse Proxies

A reverse proxy serves to act as an agent of a server that takes care of incoming requests from clients on behalf of the server. The web server may function as a one server or as a series of servers. Additionally, it can contain an application server such as Gunicorn. In either of these scenarios the request might be made by a user of the internet at large. Typically, the request will be directed directly to the web server that holds the data the client is asking for. Contrarily, a reverse proxy acts as an intermediary that isolates the web server from direct contact with the open internet.

From the perspective of the client, interfacing via reverse proxy doesn't differ from the interaction via direct connection to an internet server. It's the same thing but the client doesn't see the distinction. The client asks for the resource, and is then provided with it, with no extra configuration required from the user.

Reverse proxy providers provide features like:

• 
  
• 
  Centralized security to web server.
  
  
• 
  Incoming traffic is directed based upon rules that you can establish.
  
  
• 
  Additional functions for caching.
  
  

Central security is a benefit of both forward and reverse proxies, reverse proxies provide this feature only to the layer on the webserver and not the client layer. Instead of focusing on sustaining firewalls at the server layer which may include multiple servers that have various configurations, the bulk of firewall security is focused at the reverse proxy layer. Furthermore, taking the responsibility of communicating with firewalls and coordinating requests from clients away from web servers enables the firewall to focus on providing the required resources.

In the event of multiple servers running behind a reverse proxy, the reverse proxy can be also responsible for directing what requests are directed to which servers. Multiple web servers might be operating on the same server, each providing various kinds of resources or a mixture of both. The servers employ their HTTP protocol to serve as an ordinary web server. However, they could also be equipped with application server protocols like FastCGI. You can set up a reverse proxy to route the clients towards specific servers based on the resource requested or to comply with certain guidelines regarding the traffic load.

Reverse proxies also have the ability to make use of their position prior to web servers using caching features. The large static files can be configured using caching rules to avoid the web server from being hit with every request. Certain solutions that allow you to serve static content directly, without needing to connect to the web server in any way. In addition, the reverse proxy can be capable of handling compression of these assets.

The well-known Nginx web server is also used as a reliable reverse proxy solution. While Apache is also a reverse proxy service and it is not the only one. Apache web server also includes reverse proxy functionality, it is a different option to Apache however Nginx was designed initially for and specifically focuses on the reverse proxy features.

Differentiating Forward Proxy and Reverse Proxy Use Cases

Since "forward" as well as "reverse" are associated with an impression of directionality and false connections with "incoming" or "outgoing" traffic, the labels can be confusing since both types of proxy are able to handle requests as well as respond. Better yet, the best method to distinguish between the reverse as well as forward proxy services is to consider the requirements of the app that you are developing.

A reverse proxy could be beneficial when you're developing an application that can serve websites on the internet. They act as your web server in any interactions through the Internet.

Forward proxy can be useful when it is used before customers for your own usage, or even in a professional setting. They act as a representative of your customers in all interactions via the internet.

A case-based distinction instead of focusing solely on similar naming conventions will assist you in avoidance of confusion.

Conclusion

This article will explain what a "proxy" is and the two types that are the reverse proxy and forward proxy. Practical scenarios for use as well as an examination of the beneficial features were utilized to differentiate the two types of proxy both reverse and forward.
