The phrase "proxy" is a reference to proxy servers. A proxy or proxy server. A proxy server is an application which acts as a mediator between a client and server over the internet. Without the use of proxy servers, users could make a request for the server directly and the server would provide an answer directly for the requester. While this is a simple method to understand and apply using proxy servers, it could provide advantages in terms of improved performance and privacy, security and much more. In addition, a pass-through, a proxy acts as a security safeguard for the internet between clients and servers.

In general, the mix of hardware for servers and installed proxy software is generally known as proxy servers. This article will focus on proxies which are usually described as software as being used in conjunction with web servers. This article will give a description of the two kinds: forward proxy and reverse proxy. reverse proxy. Each kind of proxy has its own scenario, which is often misunderstood due to the similar namesake convention.

This article will provide the knowledge of what subtypes and proxies include and the things they can do in the common configurations. After reading this article, it will be able to identify the scenarios where using proxies can be beneficial, and choose the best option between forward proxy and reverse proxy for any particular scenario.

Understanding Forward Proxies

Forward proxy sometimes known in the context of open proxy. An open proxy is an agent for the user trying to send an internet request to an source server. In this case the entire attempt to send requests initiated by the client is instead sent via an forward proxy. Forward proxy acting in the place of the client will examine the request. It will first determine if the client is authorized to make requests through this specific forward proxy. It will then deny requests or redirect it to the original server. The client is not able to have direct connection to the internet. It can access only what forward proxy allows it to connect to.

The most common reason to utilize forward proxy is the need for greater privacy or security when surfing the web. A forward proxy links to the internet, not the client, and in this process, it uses an IP address that is different from the IP address that the user is using.

Based on the way it has been created, the forward proxy will offer various functions based on the configuration, which permits you to:

• 
  
• 
  Beware of Ad-trackers.
  
• 
  
• 
  Circumvent surveillance.
  
• 
  
• 
  Find restrictions that are based on your area.
  
• 
  

Forward proxies may also be utilized in systems that offer centralized security and access that is based on permissions like in workplaces. If all traffic on the internet flows through an open forward proxy, an administrator is able to restrict access to a limited number of users accessing the internet, which is then filtered by a standard firewall. Instead of creating firewalls for the client layer, which may comprise multiple computers that have different settings and users the firewall can be set up at the layer that forwards proxy data.

Take note that forward proxies must be manually set up for use, and reverse proxies may be ignored in the eyes of the user. Depending on the type IP address of a user is transmitted to the server from which it originated by the forward proxy privacy and anonymity can be granted or kept in the dark.

There are numerous alternatives to think about when considering forward proxy options:

• 
  
• 
  Apache is an well-known open-source web server, which provides forward proxy functions.
  
• 
  
• 
  Nginx: Another well-known open source web server with forward proxy capabilities.
  
• 
  
• 
  Squid is an open-source forward proxy which uses the HTTP protocol. It's not part of the entire Web server. There is a video tutorial on how to set up Squid proxy to permit private connections on Ubuntu 20.04.
  
• 
  
• 
  Dante Forward proxy that utilizes the SOCKS protocol instead of HTTP which makes it better suitable for situations such as peer-to-peer communication. It is also possible to discover how to configure Dante proxy to allow private connections on Ubuntu 20.04

Understanding Reverse Proxies

Reverse proxy is an agent for a web server which handles incoming requests from users for. The web server may comprise a single server, or a number of servers. It may also act as an application server, like Gunicorn. In any case the request will come via the internet in general. Most of the time the request will be sent direct to a server that hosts the content that the user is looking for. A reverse proxy functions as an intermediary and separates this webserver from direct interactions with the internet's open.

From the perspective of a user, the experience of using reverse proxy is no different than interacting with the webserver in direct contact. It's essentially the same but the client is unable to recognize the difference. The client makes an order for an item, and then receives it without any further configuration required by the client.

Reverse proxy providers provide features like:

• 
  
• 
  Centralized security on webservers.
  
• 
  
• 
  Direction of the traffic that is incoming based on rules that you set up.
  
• 
  
• 
  The caching function was added to the application.
  
• 
  

While central security is a benefit of both reverse and forward proxy servers. However, reverse proxies offer this benefit only to the server layer, not to the client layer. Instead of having to maintain firewalls on the web servers layer which may comprise several servers with different configurations, the majority in firewall protection is centered in the reverse proxy layer. Additionally, removing the burden of interacting with firewalls and interacting with requests from clients who do not have web servers allows them to concentrate on providing the needs of their clients.

If there are multiple servers running within a reverse proxy the reverse proxy is also accountable for directing which requests are directed to which servers. There could be several web servers providing the exact same service, but having different resources or a mixture of both. They can utilize the HTTP protocol to function as a standard web server, but they also can be outfitted with protocols for application servers like FastCGI. You can configure reverse proxy servers to direct users to specific servers based on the request for resource, or adhere to specific guidelines for the volume of traffic.

Reverse proxies also can benefit from their positioning above web servers, by providing the ability to cache information. The large static files can be configured by using caching rules in order to prevent the web server from being hit with each request. Some solutions allowing the delivery of static files directly without having to connect to a website server at all. In addition reverse proxy has the capability to compress these files.

The well-known Nginx web server also functions as a well-known reverse proxy solution. Although Apache has a reverse proxy option however, the Apache web server also has reverse proxy capability as an added option for Apache and Nginx was originally designed and focused specifically on reverse proxy features.

Differentiating Between Forward and Reverse Proxy Examples

Because "forward" as well as "reverse" are often associated with a sense of directionality, and false comparisons to "incoming" and "outgoing" traffic and can be confusing since both types of proxies handle the process of responding to requests. An alternative approach to distinguish between reverse and forward proxy is to look at the specifications of the application you're developing.

Reverse proxy is beneficial in the creation of a method to offer web-based applications on the internet. They serve as your web servers when you interact on the internet.

Forward proxy can be beneficial when it is put in front of clients for personal use or even in a working environment. They are a representation of your client's traffic whenever you connect to the internet.

The use of case-based distinction rather than using commonly used naming conventions can assist in eliminating confusion.

Conclusion

The article delineated the definition of a proxy by comparing the two types of proxy that are forward and the reverse proxy. Examples of how to use them as well as a discussion of most beneficial features were used to differentiate between forward and reverse proxy.
