Beware: 10 Proxy Sites Mistakes

A proxy also referred to proxy servers is software that acts as an intermediary between a client and server on the internet. Without a proxy, a user would send a request to something directly through a server and the server would deliver the resource directly to the user. Though this approach is simple to understand and implement, the addition of proxy servers can provide advantages in terms of improved performance, privacy, security, and many more. Alongside offering a security layer proxy servers also act as a security guardian of the internet, separating clients from servers.

The consensus is that the servers and the hardware that is used along with proxy software is often referred to proxy servers. This article will focus on proxies which are usually classified as software and within the case of web servers. We will present a summary of the two primary types that are forward proxy and reverse proxy. reverse proxy. Each has its own specific usage, which can be confusing because of a similar naming convention.

This article will provide you with an understanding of proxy's purpose and the subtypes of them, as well as how they work in the common configurations. By reading in this post, you'll learn to determine the situations that are the best to utilize a proxy and decide on the appropriate choice between forward and reverse proxy for any scenario.

Understanding Forward Proxies

In the same way, a forward proxy sometimes known as open proxy. In other words, an open proxy acts as a representative of a user who would like to forward a request via the internet to an the server that originated it. In this situation, any attempt to send requests from the client is instead routed directly via the forward proxy. Forward proxy acting on the in the place of the customer will review the request. First, it will decide if the client is authorized to receive requests from this specific forward proxy. It will then decide if it is authorized to reject an request and forward it to the original server. The client is not able to directly access the internet. It only has access to what the forward proxy grants its access.

The most popular reason to utilize forward proxy servers is to increase privacy or security when surfing the internet. A forward proxy can be used to access the internet in place of a client, and, in this way, it may use a different IP address than the original IP address that the client uses.

Based on the way it was set up in the past forward proxy servers are able to give you a variety of options. They allow you to:

• 
  
• 
  Beware of ad-tracker.
  
• 
  
• 
  Circumvent surveillance.
  
• 
  
• 
  You will be able to identify any limitations based on your geographic area.
  
• 
  

Forward proxies are also employed in systems that offer central security and authorization based access, such as at work. When all internet traffic passes through an open forward proxy, administrators can limit access to those clients who are that are filtered through a common firewall. Instead of putting firewalls to protect the client layer, which could comprise a variety of machines that have different user and environment the firewall can be placed into the forward proxy layer.

It is important to note that settings for forward proxy have to be manually configured for use to use in reverse proxies, whereas forward proxies are able to be not recognized by clients. Depending on the type of IP address of a user is passed to the original server via the forward proxy, privacy and anonymity can be granted or not.

There are a variety of options to take into consideration for forward proxies

• 
  
• 
  Apache: A popular open-source web server that has forward proxy functions.
  
• 
  
• 
  Nginx: Another well-known open-source webserver, this one with forward proxy capabilities.
  
• 
  
• 
  Squid is a free forward proxy that utilizes the HTTP protocol. Squid isn't a complete web server solution. Take a look at our step-bystep guide to create Squid proxy to allow private connections within Ubuntu 20.04.
  
• 
  
• 
  Dante forward proxy, which uses on the SOCKS protocol, instead of HTTP which makes it better suited to situations such as peer-topeer traffic. You can also look into how you can install a Dante proxy to connect privately in Ubuntu 20.04

Understanding Reverse Proxies

A reverse proxy functions as a representative of web servers that handle any requests that come in from clients on its behalf. The web server could comprise one server or several servers. Additionally, it can serve as an application server such as Gunicorn. In either of these scenarios the request for an application comes through the internet as a whole. Most of the time, the request will be directed directly to the server that hosts the data the user is asking for. A reverse proxy acts as an intermediary, shielding Web server from any direct interaction with the internet's public.

From a consumer's point perspective, which is also an individual's view, connecting using a reverse proxy is identical to working with an internet server direct. It's the same, but the user is unable to be able to discern the distinction. The client makes a request for an item and receives it, with no additional configuration required from the client.

Reverse proxies offer features like:

• 
  
• 
  Centrally secured to protect Web Server Layer.
  
• 
  
• 
  Controlling traffic coming inbound according to rules you can create.
  
• 
  
• 
  The caching functionality is now available to users.
  
• 
  

While centralized security is an advantage of both forward and reverse proxy servers, reverse proxies offer this benefit only to the server layer, it is not available to the client layer. Instead of maintaining firewalls at Web server layers which could contain multiple servers and different configurations, the bulk of the firewall security is focused at the reverse proxy layer. Furthermore, the elimination of the responsibility of interfacing with firewalls as well as dealing with clients' requests outside of web servers allows them to focus on meeting the requirements of their clients.

In the event that there's multiple servers hosted by a reverse proxy, the reverse proxy is also responsible for directing what requests go to the server. There could be multiple web servers providing similar content offering different types of resource or a combination of both. They can use the HTTP protocol similar to a traditional web server, however they could also include other protocols for application servers like FastCGI. You can also set up a reverse proxy to redirect the clients towards specific servers based on the resource requested or to follow specific rules regarding traffic load.

Reverse proxies may also make use of their position ahead of web servers, by providing the ability to cache. Large static assets can be set up using caching rules to prevent from hitting web servers on every request. There are even solutions that allow the server to serve static assets directly without connecting to the web server once. Furthermore reverse proxy solutions can handle compression of these assets.

The well-known Nginx web server also functions as a well-known reverse proxy service. While Apache is also a reverse proxy option, Apache is a reverse proxy service. Apache web server is also equipped complete with the reverse proxy feature that is an added attribute of Apache however Nginx was initially designed for and focuses on the reverse proxy feature.

Differentiating Forward Proxy and reverse Proxy Use Examples

Because "forward" or "reverse" have a connotation of directionality, and false comparisons with "incoming" as well as "outgoing" traffic, the labels can be confusing as both types of proxies handle responses and requests. An alternative method to differentiate between reverse and forward proxy is to look at the requirements of the program you're creating.

A reverse proxy could be useful when designing a solution to provide web-based applications on the internet. They are your web servers when you interact on the web.

Forward proxy is useful when placed in front of customers for personal use, or in a corporate environment. They represent your clients when you interact with the internet.

The use of case-based differentiation instead of focusing solely on commonly used naming conventions can help in eliminating confusion.

Conclusion

The article clarified the meaning of a proxy with the two kinds: the forward proxy and reverse proxy. Practical applications and a review of the most beneficial characteristics were employed to identify between reverse and forward proxies.
