A proxy, also known as a proxy is also referred to for its role as a proxy, is software that acts in the role of intermediaries between client and server via the internet. Without the proxy, a customer could send a request for every resource straight to server and servers would serve any requested resources directly to the client. Although this method is easy to grasp and use however the addition of proxy servers can offer advantages such as more performance, privacy and security, etc. In addition to providing a layer of pass-through proxy servers function as a gatekeeper for the internet between servers and clients.

The general consensus is that the system of hardware for servers, paired with proxy software is commonly called proxy servers. This article will focus on proxies that are traditionally referred to as software, and more specifically in relation with web server. We will give a synopsis of the two main kinds of proxy services: a forward proxy and reverse proxy. reverse proxy. Each kind has a distinct use, and can be confusing because of the same namestamp.

This article will give you an idea of types of proxies, their subtypes, and their value for the most common setups. By reading this article you'll be able know the scenarios where you can benefit by a proxy and decide on the appropriate option between reverse proxy and forward proxy for any situation.

Understanding Forward Proxies

Forward proxy, also known as open proxy, sometimes referred to as open proxy serves as an agent for users who wish to send a request via the internet to an source server. In this instance, any attempt to send requests made by the client will be sent through this forward proxy. A forward proxy acting in instead of the user will examine the request. It first decides if the client is authorized to accept requests through this specific forward proxy. Then, it will either reject requests or send it back to server from which it originated. The client will not be capable of having directly access to internet. it is only able to access the information that forward proxy grants it access to.

The most common applications for forward proxy servers is increased privacy or security on the internet. A forward proxy accesses the internet in lieu of a client's individual account, and during that process it may use a different IP address, in contrast to the IP address used by the user.

Depending on how it's configured, based on the way it's configured, forward proxy may offer various options and let you:

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

Forward proxies are also used in systems that provide central security and permit-based access, such as in a workplace. In the event that all internet traffic flows through an open forward proxy layer, administrator can allow only specific clients access to the internet. This is filtered by an common firewall. Instead of keeping firewalls for the client layer that could include multiple machines with different configurations and users, a firewall can be placed on the front proxy layer.

Be aware that forward proxies should be manually configured for be used, while reverse proxies can be not recognized by the client. According to the type of IP address of the client's connection to the server that generated it through the forward proxy, privacy and security can be granted or made more transparent.

There are many options to take into consideration for forward proxy:

• 
  
• 
  Apache is an well-known open-source web server that provides forward proxy capabilities.
  
• 
  
• 
  Nginx is another well-known open-source webserver, which comes with forward proxy functionality.
  
• 
  
• 
  Squid is an open forward proxy open source that uses the HTTP protocol. The option does not include the whole web server. It is possible to refer to our article on the best method for installing Squid proxy to enable private connections on Ubuntu 20.04.
  
• 
  
• 
  Dante is a forward proxy that uses the SOCKS protocol instead of HTTP this allows it to be more appropriate for situations such as peer-to-peer traffic. You can also check out how to set up an Dante proxy for private connections in Ubuntu 20.04

Understanding Reverse Proxies

Reverse proxy acts as the web server that handles the requests of customers on its behalf. It can be used as a one server, or a number of servers. Additionally, it can contain an application server like Gunicorn. In any of these instances, a request would come via the web in general. In most cases, the request is sent directly to the server with all the resources the client requires. A reverse proxy functions as an intermediary, segregating your web server from communication with the web's public.

From the point of view from a client's perspective reverse proxy isn't different from connecting directly to an internet server. It's basically the same, but clients aren't aware of the difference. The client asks for the resource and then gets it without any additional configuration required from the client.

Reverse proxy providers offer various features, including:

• 
  
• 
  A central layer of security that protects the server.
  
• 
  
• 
  Controlling traffic inbound according to rules you can establish.
  
• 
  
• 
  A new feature to cache has been added.
  
• 
  

While central security is a benefit of both forward and reverse proxy solutions, reverse proxies provide this feature only to only the server layer, it is not available to the client layer. In lieu of the maintenance of firewalls on the server level which could include multiple servers and different configurations, the bulk of firewall security can be directed at the reverse proxy layer. Additionally, removing the responsibility of dealing with firewalls as well as interacting with requests from clients that are not on web servers allows them to focus solely on meeting the requirements of their customers.

In the event of multiple servers hosting through reverse proxy it also handles the routing of requests towards which servers. There could be multiple web servers operating on the same server, serving various kinds of resources, or a mix of both. They may use an HTTP protocol to function as a standard web server, but they can additionally include application server protocols such as FastCGI. You can create a reverse proxy to route clients to particular servers based on the requested resource, or to observe certain rules for traffic volume.

Reverse proxies also can benefit from their position before web servers, by providing the ability to cache. Large static files can be set using caching rules to prevent from reaching web servers with each time a request is made. There are solutions offering the possibility of serving static content directly without having to communicate with a webserver. In addition, reverse proxy is able to help compress these assets.

The well-known Nginx web server has become a very popular reverse proxy choice. It is true that it is true that the Apache web server has a reverse proxy capabilities as an added feature for Apache however Nginx was originally designed to and focuses on the reverse proxy function.

Differentiating Forward Proxy and Reverse Proxy Use Examples

Since "forward" and "reverse" are both associated with an impression of directionality and false comparisons with "incoming" as well as "outgoing" traffic and can be confusing since both kinds of proxies handle requests and response. The best way to differentiate between forward and reverse proxy servers would be to look at the requirements of the app that you are building.

Reverse proxy is a vital element in the creation of a method to run web-based applications via the internet. They act as your servers during any interaction through the Internet.

Forward proxy can be helpful to display customers' information for your own use, or even in a workplace. They represent the client's information whenever you interact on the internet.

A distinction based on use case instead of focusing solely on similar naming conventions can help avoid confusion.

Conclusion

The article clarified definition of a proxy with two types of them being the reverse and forward proxy. Practical applications as well as an exploration of the beneficial attributes were utilized to identify forward proxies and reverse proxy.
