It is an proxy is often referred to as an application for a proxy server which serves as an intermediary between the server and the client via the internet. Without a proxy, the client could send a request a request directly to the server and the server would then deliver the resource directly back to the client. While this process is simple to comprehend and implement the addition of proxy servers may provide advantages in the form of increased security, performance, privacy, and so on. As an additional pass-through layer, proxies act as a defender to the internet between users and servers.

In general the case of server hardware and proxy software is often called proxy servers. This article we will focus on proxies typically considered as software, and specifically, in relation to web servers. There will be a discussion of the two principal kinds of proxies, which are the forward proxy and reverse proxy. reverse proxy. Each has its own specific usage case, but they're often misunderstood because of a similar name convention.

This article will give you an understanding of what proxy services as well as their subtypes are, and their use in common setups. In this article, you'll learn how to recognize the situations where you could benefit from a proxy and then select the most appropriate option between forward and reverse proxy, in each scenario.

Understanding Forward Proxies

A forward proxy, also known as the open proxy is an agent for users who are trying to transmit a request over the internet to a source server. If this is the case, all requests from the client are instead directed through this forward proxy. In this scenario this forward proxy, acting place of the client will look into the request. It is the first thing to determine whether the client is permitted to make requests via this particular forward proxy. It will then reject any request or forward it to the original server. The client has no access to internet in any way; it only has access to what the forward proxy allows it access to.

The primary reason for people to utilize forward proxy is for greater privacy or protection online. A forward proxy uses an internet connection as a client, and as such it is using an alternate IP address for the IP address of your client.

Depending on how it's been set up in the past forward proxy servers could provide a variety of functions, allowing you to:

• 
  
• 
  Avoid ad tracking.
  
  
• 
  Circumvent surveillance.
  
  
• 
  Find limitations based on your location.
  
  

Forward proxies may also be utilized in systems to provide central security and access based on permissions for instance in workplaces. In the event that all internet traffic goes through an open forward proxy layer, administrators are able to permit only a few clients access to the internet via an common firewall. Instead of establishing firewalls for the client layer which may involve many machines with varying configurations or users could be set up at an forward proxy layer.

Be aware to set forward proxy preferences must be set up manually before they are able to be used for use in reverse proxies, whereas forward proxy settings can't be observed by the user. Depending on the kind of IP address a user is relayed to the server from which it originated by the forward proxy privacy and anonymity may be granted, or in the dark.

There are a myriad of options to look into for forward-looking proxy services:

• 
  
• 
  Apache The Apache is a popular open-source server that provides forward proxy features.
  
  
• 
  Nginx is another well-known open-source server for web hosting with forward proxy capabilities.
  
  
• 
  Squid is an open-source forward proxy that utilizes the HTTP protocol. It's not a complete webserver system. We recommend you to read our guide on how you can create Squid proxy to connect privately on Ubuntu 20.04.
  
  
• 
  Dante forward proxy, which uses on the SOCKS protocol rather than HTTP this makes it better suitable for situations such as peer-to-peer traffic. You can also look into how to install a Dante proxy to permit private connections in Ubuntu 20.04
  
  

Understanding Reverse Proxies

A reverse proxy functions as an intermediary between the web server, and takes care of incoming requests from users on behalf of. This server could function as a one server or a number of servers. In addition, it could be an application-server, such as Gunicorn. In either of these scenarios a request could come from a customer via the internet in general. The request would typically be sent directly to the web server that holds all the information the user is seeking. Reverse proxy acts as an intermediary, shielding this webserver from direct communication with the open internet.

From the perspective of the client's view of the user reverse proxy use is similar to interacting with the server in its own. It's basically identical, however the client cannot tell the difference. The client requests a resource, and then receives it without any additional configuration on the part of the client.

Reverse proxy providers provide features like:

• 
  
• 
  The web server is protected centrally.
  
  
• 
  Incoming traffic is directed based upon rules you can set up.
  
  
• 
  The caching functionality has been added to the app.
  
  

Although centralized security is a benefit of both forward and reverse proxy systems, reverse proxy providers provide offer this feature only to the level of an internet server and not the layer that clients use. instead of establishing firewalls at Web server layers that may contain multiple servers with different configurations, the majority of firewall security could be focused on the reverse proxy layer. In addition, getting rid of the burden of interacting with firewalls and interfacing with requests from clients outside of web servers permits the firewall to concentrate on providing the necessary resources.

If multiple servers are operating in a reverse proxy and the reverse proxy takes care of the way requests are routed to which server. There are many web servers connected to the same server, each providing different kinds of resources or a mix of both. These servers utilize the HTTP protocol similar to a traditional web server, however they can additionally include applications server protocols like FastCGI. You can set up reverse proxy to direct clients to specific servers according to the type of resource they are looking for or to follow certain guidelines on the volume of traffic.

Reverse proxies also benefit from their positioning above web servers through the capability of caching. Massive static resources can be configured using caching rules to prevent the web server from being hit with every request. Certain options allow users to serve directly static assets without connecting with the server at all. Additionally, the reverse proxy can be able to compress these assets.

The well-known Nginx web server is a well-known reverse proxy solution. Although it is real that Apache webserver also equipped with a reverse proxy features but it's a feature available only for Apache but Nginx was designed originally for and is focused on reverse proxy features.

Differentiating Forward and reverse proxy Use Differentiating Forward Proxy and Reverse Proxy Use

Because "forward" in addition to "reverse" come with connotations of directionality, and false comparisons to "incoming" as well as "outgoing" traffic, these labels can confuse because both types of proxies respond to requests and receive responses. In addition, the most effective method to distinguish between reverse and forward proxy is to study the requirements of the app you're creating.

Reverse proxy is an effective tool when you're designing a solution to deliver web-based applications over the internet. They represent your web servers every time you use the internet.

Forward proxy is useful to display clients for personal use or in a working environment. They are a representation of information about the client every time you connect to the internet.

Separating by case of use instead of using the same names will ensure that you won't be confused.

Conclusion

This article will explain what a proxy is and compares the two major types which are the reverse proxy and forward proxy. Practical examples of use as well as a discussion of the most beneficial attributes were used to determine the difference between forward and reverse proxies.
