It is a proxy, also called a proxy server, is a software that serves as a mediator between a client and server on the internet. Without a proxy, a client can make a request for any resource directly to the server and the server would deliver the resource directly to the user. While this is a simple method to grasp and implement, the addition of proxies can bring advantages in the form of increased performance, privacy, security, and many more. As a pass-through layer, a proxy serves as a security guardian of the internet between servers and clients.

The consensus is that the mix of hardware for servers and software for proxy installation is often referred too as proxy servers. This article will concentrate on proxy servers that are usually classified as software as well as when referring to web servers. There will be a discussion of the two primary types that are forward proxy and reverse proxy. reverse proxy. Every one has its unique unique usage scenario that is frequently not understood due to the similar terminology.

This article will provide you with some knowledge about the types of proxies and what subtypes they are and how they operate in common configurations. After having read this article, you'll be able to determine the circumstances where you could benefit from a proxy and then decide which is the best choice between forward and reverse proxy for any particular scenario.

Understanding Forward Proxies

The forward proxy, also known in the form of an open proxy serves as the representative of a customer who wants to forward a request over the internet to a source server. In this instance, the whole request sent by the user will be forwarded by the forward-proxy. The forward proxy, acting in the client's stead, will review the request. The first step is to determine if the client is permitted to accept requests from this particular forward proxy. It then decides whether to decline a request and forward it to the original server. The client isn't allowed an internet connection directly. It has access to only what forward proxy permits the client to access.

A common use of forward proxy servers is to obtain more privacy or protection on the internet. Forward proxy can be used to access the internet in place of a client and in this manner it could utilize an IP address that is different from the client's original IP address.

Depending on how it's been configured, the forward proxy will provide different functions, based on the configuration that lets you:

• 
  
• 
  Stay clear of tracking ads.
  
  
• 
  Circumvent surveillance.
  
  
• 
  Find restrictions based on the location you are in.
  
  

Forward proxies can also be used to secure systems that are centralized and permission-based access, such as in a workplace. Every internet connection can go via the open forward proxy. an administrator can grant just a few users online access using an ordinary firewall. Instead of creating security firewalls on the server layer which could comprise a range of computers with different settings and users. A firewall can be placed in the intermediate layer of forward proxy.

It is vital to note that forward proxies must be manually set up to be used, however reverse proxies remain undetected by clients. Based on the fact that the IP address of a user is sent to the server that originated it from the forward proxy, privacy and anonymity might be granted or unnoticed.

There are a myriad of possibilities to look into forward proxy options

• 
  
• 
  Apache: A popular open-source web server which provides forward-looking proxy services.
  
  
• 
  Nginx is another popular open-source web server with forward proxy capabilities.
  
  
• 
  Squid is an open-source forward proxy that makes use of the HTTP protocol. It does not come with an complete website server program. You can check out our tutorial on installing Squid proxy for private connections in Ubuntu 20.04.
  
  
• 
  Dante Forward Proxy that utilizes the SOCKS protocol instead of HTTP which makes it more to handle peer-to-peer connections. It is also possible to investigate how to set up a Dante proxy for private connections in Ubuntu 20.04
  
  

Understanding Reverse Proxies

A reverse proxy serves as a webserver, which takes care of requests from clients on its behalf. The web server may serve as a single server, or as a set of servers. It can also serve like an app server, such as Gunicorn. In either of these scenarios the request will come from an internet-connected user. The request is typically directed directly to the server that has the resources that the user needs. Instead, a reverse proxy functions as an intermediary and shields it from any direct contact with the open internet.

From the perspective of the client, interfacing via reverse proxy isn't distinct from communicating with the web server directly. It's functionally identical and the user doesn't see the difference. The client sends requests for resources, which is followed by receiving it with no additional configuration needed from the user.

Reverse proxies can provide features such as:

• 
  
• 
  Security centralized for web servers.
  
  
• 
  Sending traffic to be directed according to rules that you determine.
  
  
• 
  Additional functions to cache data.
  
  

While central security is a benefit of both forward and reverse proxy servers. Reverse proxy servers provide this benefit to the web server layer but not the client layer. Instead of having to maintain firewalls at the web server layer, which can contain multiple servers with different configurations, the bulk of the firewall security can be handled by the reverse proxy layer. Furthermore, getting rid of the hassle of dealing with a firewall and interacting with requests from clients away from web servers lets them focus on serving the resources.

If multiple servers are running in a reverse proxy, the reverse proxy also handles how requests are routed which server. There could be multiple web servers that provide the identical service, and each offering different types of resources or a mix of both. They may utilize the HTTP protocol to function as a standard web server, however, they could also incorporate application server protocols such as FastCGI. You can create reverse proxy that routes users to specific servers based on the resource requested or to observe specific rules for traffic volume.

Reverse proxies also can profit from their positioning over web servers by offering caching capabilities. Large static assets can be set up by using caching rules to stop the web server from being hit with every request, with some solutions providing the option to upload static files directly without connecting to a web server even once. Additionally, reverse proxy is able to handle the compression of these assets.

The popular Nginx webserver is also a very well-known reverse proxy solution. While Apache has a reverse proxy option but it is not a reverse proxy solution. Apache web server does have reverse proxy capabilities as an additional option to Apache and Nginx was designed originally for and was designed with a focus on reverse proxy capabilities.

Differentiating Forward Proxy and reverse Proxy Use Differentiating Forward Proxy and Reverse Proxy Utilization

Since "forward" and "reverse" have connotations of directionality, as well as false connections to "incoming" as well as "outgoing" traffic the labels could be confusing since both kinds of proxy deal with requests and responses. In addition, the most effective method of separating between reverse and forward proxy is to examine the requirements of the app that you're developing.

Reverse proxy is an important aspect when designing a solution to host websites on the internet. They are your web servers for any interaction on the internet.

A forward proxy is beneficial for use in front of customers for your own use or even in a workplace. They serve as the proxy for your client for any interaction on the internet.

Utilizing use cases to differentiate rather than focusing solely on the common naming conventions makes it easier to avoid confusion.

Conclusion

The article explained the meaning of a proxy and two types of proxy, the forward proxy and reverse proxy. Practical scenarios for using them and a discussion of the most useful features were utilized to differentiate forward proxies from reverse proxies.
