proxy, also referred to as proxy, also known as proxy or proxy server is a server software that sits as a mediator between a client and server over the internet. With no intermediary users would make a request for something directly to a server and servers would serve the requested resource directly back to the user. Although this approach is simple to comprehend and use, adding proxies offers advantages such as increased security, performance, privacy, and much more. A pass-through layer proxy serves as a security barrier on the internet between servers and users.

In general, the bundled bundle of server hardware and proxy software is called proxy servers. This article will concentrate on proxy servers that are generally referred to as software, as well as those that are used in conjunction with web servers. We will present a summary of the two main types that are available, which is the forward proxy and the reverse proxy. Each has its own use case, and is often misunderstood because of the identical terminology.

This article will provide you with an idea of the different types of proxy services and the subtypes are as well being able to explain how they can be useful in the typical configurations. In this article, you will be able to recognize the situations where you can benefit from a proxy and determine the most appropriate choice between reverse and forward proxy options in any given scenario.

Understanding Forward Proxies

The forward proxy often called open proxy, also known as open proxy is an agent for the user who wants to send a request through the internet to an the server which originated it. In this scenario it is the scenario that all requests sent by the client should be routed directly towards the forward proxy. The forward proxy, acting in place of the client will examine the request. At the beginning, it will determine if the client is able to handle requests through this specific forward proxy. It then decides whether to refuse requests or redirect it to the original server. The client is not able to have direct access to the internet; it can only access what forward proxy grants the client access.

The most popular reason to use forward proxies is to gain greater privacy or security on the internet. A forward proxy is able to connect to the internet on behalf of clients. In the process, it will use an alternative IP address to the IP address originally utilized by the client.

Based on the way it has been configured according to the way it was set up, a forward proxy could offer you a range of functions as well as the ability to:

• 
  
• 
  Stay clear of tracking ads.
  
  
• 
  Circumvent surveillance.
  
  
• 
  You can identify limitations based on your geographic area.
  
  

Forward proxies are also used in systems that offer central security as well as access to users based on their permissions, for instance in a workplace. If all internet traffic flows by an open forward proxy, an administrator can restrict access to certain individuals to access the web, which is then filtered by a typical firewall. Instead of keeping firewalls in place for the client layer, which can comprise a range of devices that are different in terms of user and environment A firewall can be set up in the forward proxy layer.

It is important to remember that forward proxy servers have to be set up manually before they are able to be used for use, while reverse proxy servers are not able to be noticed by the user. Based on the fact that your IP address a user is passed to the server that generated it via the forward proxy privacy and anonymity may be granted or left transparent.

There are several alternatives to think about when it comes to forward proxy options:

• 
  
• 
  Apache An open-source, well-known web server that provides forward proxy functionality.
  
  
• 
  Nginx: Another well-known open-source server for hosting websites with forward proxy capability.
  
  
• 
  Squid: A free forward proxy that utilizes the HTTP protocol. It's not the complete Web server. Read our guide on how to set up Squid proxy to allow private connections in Ubuntu 20.04.
  
  
• 
  Dante Forward proxy that uses the SOCKS protocol instead of HTTP to allow it to be more suitable for use scenarios like peer-to-peer communication. You might also want to know how to set up Dante proxy for private connections on Ubuntu 20.04
  
  

Understanding Reverse Proxies

A reverse proxy functions as a representative of the web server which takes care of incoming requests from clients on behalf of. The web server can be one server or several servers. In addition, it could represent an application servers, such as Gunicorn. In all of these scenarios, an application request is made from a user on the internet. In most cases the request will go directly to the web server that hosts the data the client is seeking. Contrarily reverse proxy serves as an intermediary that helps to protect Web servers from direct interactions with the open internet.

From the perspective of a person's perspective, working with reverse proxy is not any different from working with Web server in direct contact. It is functionally the same as the web server, and the user is unable to discern the difference. The client can request the resource, and receive it, without any additional configuration required on the part of the client.

Reverse proxy providers provide the following features:

• 
  
• 
  Centrally secured to protect Web Server Layer.
  
  
• 
  Directing incoming traffic based on rules you set.
  
  
• 
  The caching functionality was added to the application.
  
  

While central security is a benefit of both reverse and forward proxy services, reverse proxies apply this function to the web server layer and not to the client layer. In lieu of maintaining firewalls in the web server layer which may contain multiple servers that are configured differently, most of the firewall security is aimed on the reverse proxy layer. Also, the removal of the responsibility to interact with a firewall and responding to requests from clients via web servers allows them to concentrate on meeting the requirements of their clients.

In the event of multiple servers operating through a reverse proxy, the reverse proxy can also be accountable for directing the requests that are directed to which server. There may be several web servers hosting identical resources, but each offering different types of resources or a combination of the two. These servers may be running the HTTP protocol to operate as a standard internet server, but they can include applications server protocols like FastCGI. There is the possibility to configure reverse proxy servers to direct visitors to a specific server based on the type of resource they are looking for, or to follow certain guidelines regarding traffic load.

Reverse proxies also can utilize their position before web servers by delivering the ability to cache. Large static assets are capable of being configured with caching rules to prevent getting into web servers with every request. There are options that offer the possibility of providing static files directly without connecting directly to the website server. Additionally, the reverse proxy is able to manage compressing these assets.

The well-known Nginx webserver is an extremely popular reverse proxy option. Although Apache can also be regarded as a reverse proxy solution however, the Apache web server is equipped with a reverse proxy feature, which is a different characteristic that is part of Apache but Nginx was initially designed and focused on the reverse proxy function.

The difference is between Forward Proxy and Reverse Proxy Use Situations

Since "forward" and "reverse" are associated with directionality, they can also lead to inaccurate comparisons to "incoming" or "outgoing" traffic. They could be confusing since both kinds of proxies are able to respond to requests as well as responses. Better yet, the best method to differentiate between the forward and reverse proxies would be to look at the requirements of the application that you are building.

Reverse proxy is beneficial when creating a solution to deliver web applications to the internet. They function as servers when you are on the internet.

Forward proxy are useful when it is placed before the client for personal use or in a workplace setting. They serve as the proxy for your client when you use the internet.

Distinguishing by use case in lieu of looking at similar names will ensure that you aren't confused.

Conclusion

This article explains what a proxy is with two types of proxy, namely the forward proxy as well as the reverse proxy. Practical applications as well as an exploration of useful features were utilized to differentiate between reverse and forward proxies.
