The term "proxy" refers to the notion of a proxy frequently known as proxy server software that serves to act as an intermediary for server and client on the internet. Without a proxy, a client could send a request to the server directly, and the server would then serve an item directly for the client. While this approach is straightforward to understand and use, proxies can provide advantages such as more performance and security, privacy, and so on. As a layer of pass-through, the proxy acts as a security layer to the internet between users and servers.

The general combination of server hardware and the software to install proxy servers is usually called proxy servers. This article will concentrate on proxy servers that are typically considered to be software but specifically with respect with web server. This article will give a synopsis of the two principal kinds of proxies, which is a forward proxy and reverse proxy. reverse proxy. Each type comes with its own usage scenario, which is often misinterpreted due the similar terms.

This article will provide you with an idea of what proxies as well as their subtypes and ways they can be useful in various configurations. If you read this article you'll discover instances where using proxies can be beneficial and identify the most appropriate alternative between forward proxy and reverse proxy for a particular scenario.

Understanding Forward Proxies

The forward proxy also known by the name of the open proxy is the client's representative who is trying to relay requests via the internet to a server that is the source. In this case every attempt to send a request by the user will instead be sent via an forward proxy. The forward proxy, taking the place of the client examines the request. Then, it will decide whether the client is permitted to send requests via this specific forward proxy. Then, it will decide whether to reject the request or forward it to the server that originated the request. The client is not able to have direct connection to the internet. It is only able to connect to what forward proxy allows it to connect to.

The primary reason for people to use forward proxies is to gain greater security or privacy when surfing the internet. A forward proxy can be used to access the internet instead of clients, and in this manner, it is using an alternative IP address to the IP address that was originally used by the client.

Based on the way it's configured, and how it is configured, forward proxy may offer a range of functions and allow you to:

• 
  
• 
  Beware of ads-trackers.
  
  
• 
  Circumvent surveillance.
  
  
• 
  You will be able to identify any restrictions based on your geographical place of residence.
  
  

Forward proxies can also be used to secure systems that are centralized and access dependent on permissions, for instance at work. In the event that all internet traffic flows through a common forward proxy layer, an administrator might restrict access for just a small number of internet users, which is filtered by an common firewall. Instead of setting up firewalls for the client layer, which can be used by a number of computers that have different settings and types of users, it is possible to establish a firewall at the layer that forwards proxy traffic.

It is important to note that forward proxies need to be configured manually to be used, while reverse proxy servers can be hidden from the view of clients. Based on whether or not an IP address belonging to the user is relayed to the origin server through the forward proxy, privacy and anonymity can be granted or not.

There are a variety of options to consider for forward proxy services.

• 
  
• 
  Apache An open-source, well-known web server that comes with forward proxy capabilities.
  
  
• 
  Nginx is another widely-used open-source webserver that includes forward proxy capabilities.
  
  
• 
  Squid: A no-cost forward proxy which uses an HTTP protocol. It's not part of the entire web server. Learn more about how to set up Squid proxy to allow private connections in Ubuntu 20.04.
  
  
• 
  Dante Forward proxy that utilizes the SOCKS protocol instead HTTP which is more appropriate for applications like peer-to-peer traffic. You might also want to check out how to configure Dante proxy to permit private connections in Ubuntu 20.04
  
  

Understanding Reverse Proxies

Reverse proxy serves as an agent for a server on the internet, which handles requests from customers on behalf of. It could represent one or more servers. Also, it could be an application server, such as Gunicorn. In either case, a request would come via the internet in general. Typically, the request is sent directly to the web server that hosts the resources that the client requires of. In contrast, a reverse proxy is a intermediary that isolates the web server from direct interaction with the internet's public.

From the perspective of the client an individual's perspective, the process of using reverse proxy isn't any different from interacting with the server on its own. It's exactly the same however the client can't be able to discern the distinction. Client makes a request for the resource and is then supplied with it, without any additional configuration required from the user.

Reverse proxies provide features like:

• 
  
• 
  The web server is protected centrally.
  
  
• 
  Traffic coming into your site is routed based upon rules you set.
  
  
• 
  A new feature for caching is now available.
  
  

While central security is a benefit of both forward and reverse proxy servers. However, reverse proxies offer this feature to only the server layer but they do not offer this feature to clients. In lieu of maintaining firewalls at the server level that may contain multiple servers with different configurations, the majority of security for firewalls is concentrated on the reverse proxy layer. In addition, removing the burden of working with a firewall and connecting to client requests off web servers enables the firewall to focus on serving the needs of their customers.

If there are multiple servers being hosted by a reverse proxy, it is also responsible for how requests are routed through the server that is hosting them. There could be multiple web servers providing the same service, but offering various kinds of resources or a mix of both. The servers could use their HTTP protocol to function as a standard web server, however they can also use protocols for application servers like FastCGI. You can also set up a reverse proxy to direct users to specific servers based on the resource being requested, or to adhere to certain rules for traffic load.

Reverse proxies can also benefit from their position before web servers by offering caching capabilities. Large static assets can be set using caching rules to prevent hitting web servers each time you request. There are options that allow you to serve directly static assets, without connecting directly to web servers in any form. In addition, the reverse proxy is able to compress these assets.

The well-known Nginx web server can also function as an effective reverse proxy option. Although Apache has a reverse proxy solution, the Apache web server comes fitted with reverse proxy feature that is an additional feature that is available for Apache but Nginx was designed originally specifically for reverse proxy capabilities.

The difference between Forward Proxy and Reverse Proxy Use Situations

Because "forward" as well as "reverse" come with connotations of directionality and misleading comparisons to "incoming" as well as "outgoing" traffic The labels can be confusing since both types of proxy servers handle the processing of requests and replies. A better approach to differentiate between reverse and forward proxy is to study the requirements of the application you're creating.

A reverse proxy is useful when you're developing a method to connect web applications to the internet. They serve as your web servers whenever you interact using the internet.

Forward proxy is beneficial when they are used before customers for your personal use or in a professional setting. They act as your client's proxy when you are on the internet.

The ability to differentiate by the use of case instead of solely focusing on the common naming conventions will help you avoid confusion.

Conclusion

This article describes what a proxy is with two kinds: forward proxy and the reverse proxy. Practical examples of use as well as a look at the beneficial features were used to distinguish forward proxies and reverse proxies.
