proxy, also known as a proxy or proxy server, is a server software that acts in the middle between a client and server on the internet. Without an intermediary, users would make a request to purchase an item direct to a server, and servers would deliver the requested resource directly back to the client. Although this approach is simple to comprehend and implement, proxies can provide benefits such as improved security, performance, privacy and more. A proxy that is a pass-through layer serves as a security barrier on the internet between servers and clients.

Generally speaking it is the bundled set of server hardware with installed proxy software is often described as proxy servers. However, this article will focus on proxy servers which are usually referred to as software, as well as ones that work in conjunction with web servers. We will provide a brief overview of the two main types, namely a forward proxy and the reverse proxy. Each comes with its own specific application scenario, and it can be misinterpreted due to the identical terms.

This article will give you an idea of the different types of proxy services and the subtypes are, as as how they are useful for the most common configurations. In this article, you can identify the situations in which you can benefit from proxy services and determine the most appropriate option in between forward and reverse proxy for any particular situation.

Understanding Forward Proxies

The forward proxy also referred to as open proxy, also known as open proxy is an agent for the user who wants to make a request via the internet to an the server that originated the request. In this case, it's the case that all requests made by the client would rather be directed straight at the forward proxy. The forward proxy, in the position of the customer, will look over the request. It will determine whether the client is able to accept requests from this specific forward proxy. It will then decide whether to reject requests or redirect them to the server that originated it. The client is not able to have an internet connection directly but it is able to access what the forward proxy gives to access.

The most common reason to use forward proxies is to gain greater privacy or security on the internet. Forward proxy allows you to connect to the internet in place of clients, and in the process, it will use an alternative IP address to the IP address that was originally used by the client.

Based on how it has been configured according to the way it was initially configured forward proxy may offer you a range of functions and the capability to:

• 
  
• 
  Beware of ads that track you.
  
  
• 
  Circumvent surveillance.
  
  
• 
  You will be able to identify any limitations based on your geographical place of residence.
  
  

Forward proxies are also used in systems that offer central security, as well as permission-based access, like at work. In the event that all traffic on the internet is routed via an open forward proxy, administrators can grant access only to specific individuals to access the web. This is then filtered by a typical firewall. Instead of having firewalls installed for the client layer, which may comprise several computers that have different users and environments, a firewall could be installed on top of an forward proxy layer.

Be aware that forward proxies need to be set up manually before they can be used in order to be used, while reverse proxies are able to not be detected by the user. Based on the fact that the IP address of a user is sent to the server which originated it by the forward proxy privacy and anonymity may be granted or made transparent.

There are several alternatives to think about for forward proxies:

• 
  
• 
  Apache A well-known, open-source web server with forward proxy capabilities.
  
  
• 
  Nginx: Another well-known open-source server for web hosting with forward proxy capability.
  
  
• 
  Squid: A free forward proxy that uses the HTTP protocol. It's not the complete web server service. Check out our tutorial on how to configure Squid proxy for private connection on Ubuntu 20.04.
  
  
• 
  Dante Forward proxy that uses the SOCKS protocol instead HTTP to make it more suited to use scenarios like peer-to-peer communication. It is also possible to examine how you can create a Dante proxy to allow private connections using Ubuntu 20.04
  
  

Understanding Reverse Proxies

Reverse proxy is an intermediary for a web server, which handles any requests that come in from clients on behalf. The web server could represent a single or multiple servers. It could also represent an application servers, like Gunicorn. In all these instances, the request for an application comes by a user who is on the internet in general. In most cases, the request will go directly to the server that hosts the information the client is seeking. In contrast, a reverse proxy functions as an intermediary in order to shield Web servers from direct interaction with the open internet.

From a perspective of the person's perspective, working via reverse proxy is the same as working with Web server directly. It is functionally the same as the web server and the client is unable tell the distinction. Clients can make a request for the resource and it receive it without any additional configuration required on the part of the client.

Reverse proxies grant the following features:

• 
  
• 
  Secured centrally for Web Server Layer.
  
  
• 
  Directing incoming traffic according to rules you have set.
  
  
• 
  The caching functionality was added to the application.
  
  

Although centralized security is an advantage of both reverse and forward proxy servers, reverse-proxies do this function to only the layer of web servers not the client layer. instead of the maintenance of firewalls within the layer of web servers which may contain multiple servers that are configured differently the majority of firewall security is focused on the reverse proxy layer. Additionally, the elimination of the responsibility of interfacing with a firewall and connecting with requests from customers off of web servers enables them to focus solely on meeting the requirements of their clients.

In the event of multiple servers running through reverse proxy the reverse proxy may be also responsible for directing the requests that are directed to which server. There could be multiple web servers hosting identical resources, each offering different types of resources or a combination of the two. They can use an HTTP protocol to serve as a standard web server, but they also include applications server protocols like FastCGI. It is possible to configure reverse proxy servers redirecting visitors to a particular server according to the type of resource they're looking for, or to follow certain guidelines regarding traffic load.

Reverse proxies are also able to make use of their position prior to web servers through the capacity of caching. Large static assets are capable of being configured with rules for caching to avoid hitting web servers on every request. There are solutions offering the possibility of providing static files directly without connecting directly to the website server. Furthermore, the reverse proxy will manage the compressing these assets.

The renowned Nginx website server also an extremely well-known reverse proxy choice. Although Apache can also be regarded as a reverse proxy solution it is not the only one. Apache web server is also equipped with a reverse proxy function, it is a distinct option in Apache but Nginx was designed originally for and focused on the reverse proxy function.

The distinction in Forward Proxy and Reverse Proxy Use Cases

Because "forward" or "reverse" are both associated with directionality, they can also lead to misleading comparisons with "incoming" as well as "outgoing" traffic, they could be confusing since both types of proxy are able to manage requests and responses. The best method to distinguish between reverse and forward proxies is to look at the needs of the application you're creating.

A reverse proxy could be helpful when building an approach to connect web-based applications on the internet. They act as your servers when you interact using the internet.

Forward proxy can be beneficial when they are put in front of the user for personal use or in a workplace setting. They are your client's proxy when you use the internet.

Distinguishing by use case instead of focusing on similar naming conventions will make sure that you don't get confused.

Conclusion

This article clarified what a proxy is along with two kinds, specifically the forward proxy and the reverse proxy. Practical applications as well as an exploration of useful features were utilized to distinguish between reverse and forward proxies.
