The term "proxy" refers to a proxy is also known as a proxy server is piece of software that acts as an intermediary between client and server on the internet. Without proxy servers, a user could send a request for resources directly to a server, and it would serve the resource directly to the user. While this is a simple method to grasp and implement however, adding proxy servers can bring advantages such as increased efficiency, privacy, security, and more. In addition to providing pass-through, the proxy serves as a guardian to the internet, separating clients from servers.

The bundled system of server hardware coupled with installed proxy software is often called proxy servers. This article will focus on the proxies that are usually considered to be software, and in the context of web servers. There will be a discussion of the two major types of proxies, the other being forward proxy and the other being a forward proxy and reverse proxy. reverse proxy. Each kind has its own specific application, and is frequently confused because of the similar namesake convention.

This article will provide you with an idea of the different subtypes and proxies, as well as their benefits for setups that are common. If you read in this post, you'll be able discern situations in which the use of proxy servers is beneficial, and you can then select the best option between forward proxy and reverse proxy based on the situation.

Understanding Forward Proxies

Forward proxy also known in the context of open proxy. An open proxy is the agent of a user who would like to make an internet-based request to an the server that originated it. In this situation, all attempts to send requests made by the client's end will instead be sent to the forward proxy. Forward proxy in place of the client will examine the request. First, it will find out if the client is authorized to receive requests from this specific forward proxy. It will then deny any request, or send it to its origin server. The client does not have an internet connection directly It can only access what forward proxy permits it to connect to.

The primary reason for people for using forward proxy servers is to increase privacy or security online. A forward proxy accesses the internet as clients, and as such it may make use of an IP address different from the IP of the user.

Depending on how it's been set up, the forward proxy can give you a range of options in addition to the ability to:

• 
  
• 
  Beware of ad-tracker.
  
• 
  
• 
  Circumvent surveillance.
  
• 
  
• 
  Find restrictions that are based on your area.
  
• 
  

Forward proxies also are employed in systems that offer central security and access based on permissions, such as in workplaces. When all internet traffic flows through a forward proxy and administrators are in a position to grant only specific clients to access the internet using a common firewall. Instead of putting firewalls in place to protect the client layer which could include multiple machines with varying settings and environment the firewall is put in an forward proxy layer.

It is important to remember to set forward proxy preferences have to be manually setup to allow them to be used in order to be used, while reverse proxy servers are unable to be detected by users. Based on whether or not your IP address a user is transmitted to the server from which it originated via forward proxy privacy and security may be granted or not.

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

• 
  
• 
  Apache An open source well-known web server with forward proxy capabilities.
  
• 
  
• 
  Nginx Another well-known open-source server used for web hosting with forward proxy capabilities.
  
• 
  
• 
  Squid: A no-cost forward proxy that utilizes it's HTTP protocol. It's not the complete Web Server System. It is possible to refer to our article on the best method to set up Squid proxy to allow private connections in Ubuntu 20.04.
  
• 
  
• 
  Dante Forward proxy that makes use of the SOCKS protocol instead of HTTP and HTTP, which makes it better suited to scenarios such as peer-to-peer communication. You can also check out how to set up Dante proxy for connection to private networks in Ubuntu 20.04

Understanding Reverse Proxies

Reverse proxy serves as an intermediary to web servers, and is able to handle requests from customers for the web server. The web server may serve as a single server or a number of servers. In addition, it could serve as an application server, such as Gunicorn. In any case an application request comes through the internet in general. Most of the time, the request will directly go to the web server that hosts what the client is looking for. A reverse proxy acts as an intermediary to isolate your website server from communication with the internet's open.

From the perspective of a user's view, interacting with reverse proxy doesn't differ from connecting to Web server in direct contact. It's functionally identical, but the user can't discern the difference. The client requests an item and gets it with no additional configuration needed from the user.

Reverse proxy providers provide features like:

• 
  
• 
  The server on the internet is protected centrally.
  
• 
  
• 
  Sending traffic to be directed in accordance with the rules you have set.
  
• 
  
• 
  A new feature for caching has been added.
  
• 
  

While centralized security is an advantage of both reverse and forward proxy, reverse proxies do this feature only to the web server layer but not to the client layer. instead of the maintenance of security firewalls in Web server layers that may include multiple servers with different configurations, the bulk in firewall protection is aimed at the reverse proxy layer. In addition, taking the burden of interfacing with firewalls and responding to clients' requests off of web servers enables them to concentrate on providing resources.

If there are multiple servers with a reverse-proxy in place, the reverse proxy is also accountable for deciding which requests are directed to which server. There could be multiple web servers operating on the same server, each serving different kinds of resources or a mixture of both. These servers may use the HTTP protocol, which is similar to a traditional web server. They may also use protocols for application servers like FastCGI. You can also configure reverse proxy settings to redirect the clients towards specific servers depending on the service requested or to adhere to certain rules regarding traffic load.

Reverse proxies also can benefit from their position over web servers with the help of caching. Large static assets can be configured with caching rules in order to avoid hitting web servers with every request, with some solutions even allowing users to upload static files in a direct manner without linking with the server. In addition, the reverse proxy can manage compression of these files.

The popular Nginx web server has become a wildly popular reverse proxy service. Although the Apache web server also comes with the reverse proxy option as an additional feature that is available to Apache while Nginx was originally designed to and focused on reverse proxy functions.

Differentiating Forward Proxy from reverse Proxy Use Cases

Because "forward" in addition to "reverse" are both associated with an impression of directionality, and also false comparisons with "incoming" and "outgoing" traffic, these terms can be confusing as both types of proxies can be used to handle requests as well as responses. A different method of distinguishing between reverse and forward proxy servers would be to study the needs of the application you're creating.

Reverse proxy is a useful tool when you're developing a solution to serve websites on the internet. They act as your servers during any interaction through the Internet.

Forward proxy is a great tool to use if you're working with clients in front for personal usage or even in a work environment. They can be used to represent the traffic of your clients when you are on the internet.

A distinction that is based on the use rather than looking at the common names can help in avoidance of confusion.

Conclusion

The article described what a proxy is along with two types being the reverse proxy and forward proxy. Practical examples of its use as well as a discussion of most effective features were utilized to distinguish forward proxies from reverse proxies.
