Confidential Information on Proxy Sites That Only The Experts Know Exist > 자유게시판

It's a proxy which is also known as a proxy server. It is a software that serves to act as mediator between client and server over the internet. Without a proxy, a client would be able to make a request for every resource straight to the server, and the server will provide the resource directly at the request of the customer. Although this method is simple to understand and implement, the addition of proxy servers can provide advantages in the form of improved performance and privacy, security and many other benefits. As a pass-through layer a proxy acts as an additional security layer on the internet between clients and servers.




The consensus is this: the mix of servers hardware and the software to install proxy servers is often referred too as proxy servers. This article will concentrate on proxy servers which are generally classified as software as well as when referring to web servers. The article will provide a detailed discussion of the two primary types, namely which are a forward proxy and reverse proxy. reverse proxy. They each have their own usage scenario that is frequently not understood due to the similar terms.




This article will provide you with some knowledge about the types of proxies and the subtypes of them and how they function in the most common configurations. After reading this article, it will be able determine the situations in which you can benefit by a proxy, and decide which is the best choice between forward and reverse proxy in every scenario.



Understanding Forward Proxies



The forward proxy also known as an open proxy serves as the representative of a user who would like to forward a request over the internet to an source server. In this scenario, the entire attempt to send requests by the user is instead sent to the forward-proxy. The forward proxy, acting as a substitute for the client will review the request. The first process is to determine if the client is permitted to accept requests via this specific forward proxy. Then, it decides to reject an request and forward it to the original server. The client is not allowed direct access to the internet. It is only able to access what the forward proxy allows the client to access.




A popular use for forward proxy is to achieve greater privacy or security online. A forward proxy is able to access the internet in place of a client and in this manner, it may use a different IP address than the client's original IP address.




Depending on how it has been configured, the forward proxy will offer various functions based on the configuration that lets you:




Avoid tracking ads.


Circumvent surveillance.


Find restrictions that are based on the location you are in.




Forward proxies are also used to secure systems which are centralised and have permission-based access, such as in the workplace. The entire internet can be passed by an open forward proxy, administrators can allow just a few users connection to internet via an common firewall. Instead of establishing security firewalls on the server layer, which may comprise a variety of computers with different settings and users. A firewall can be installed on top of an front proxy layer.




It is important to remember that forward proxies need to be set up manually to use however reverse proxies will be ignored by users. Based on the fact that the IP address of a user is transmitted to the origin server by the forward proxy, privacy and anonymity might be granted, or left unnoticed.




There are a myriad of possibilities to explore for forward proxy options:




Apache: A popular open-source web server which provides forward proxy functions.


Nginx is another popular open-source webserver that comes with forward proxy features.


Squid is an open source forward proxy that utilizes the HTTP protocol. It doesn't come with an complete web server application. Check out our instructions on setting up Squid proxy to connect privately for private connections on Ubuntu 20.04.


Dante Forward Proxy that utilizes the SOCKS protocol instead of HTTP which makes it better to handle peer-to-peer communication. It's also worth taking a look examine how you can setup an Dante proxy to connect privately in Ubuntu 20.04



Understanding Reverse Proxies



A reverse proxy serves as a webserver, which takes care of requests from clients in its place. The web server may serve as a single server or multiple servers. Additionally, it can be used like an app server, such as Gunicorn. In any of these situations, the request comes from a customer via the internet. The request is typically directed directly to the web server which is the one that has the resources the user wants. Instead, a reverse proxy functions as an intermediary and shields it from any direct contact with the open internet.




From the point of view of the user, working via reverse proxy isn't distinct from communicating with your webserver directly. It's essentially the same, and the user doesn't see the distinction. Clients make a request for a resource and then receiving it without any extra configuration required from the user.




Reverse proxies offer features like:




Centralized security for the web server layer.


Sending traffic to be directed according to the rules you can define.


Additional functionality for caching.




While central security is a benefit of both reverse and forward proxy servers. Reverse proxy services provide this benefit to the web server layer, but not the layer that clients use. Instead of having to maintain firewalls on the layer of web servers which can contain several servers that have different configurations, the majority of firewall security may be concentrated at the reverse proxy layer. Additionally, getting rid of the hassle of dealing with firewalls and interfacing with clients who request information from web servers lets them focus on serving the resources.




If there are multiple servers running behind a reverse proxy, the reverse proxy handles the way requests are routed to which server. There could be multiple web servers providing the exact same service, all offering various kinds of resources or a mix of both. They may utilize the HTTP protocol for a traditional web server, but they could also incorporate protocols for application servers like FastCGI. You can set up reverse proxy servers to direct users to specific servers based upon the requested resource or to follow certain guidelines regarding traffic volume.




Reverse proxies can also benefit by their position over web servers, by providing the ability to cache data. The large static files can be created by using caching rules to stop the web server from being hit with every request. Certain options allowing users to provide static files without having to connect to the web server once. In addition, the reverse proxy can manage the compression of these assets.




The well-known Nginx website server a highly well-known reverse proxy solution. While Apache can also be a reverse proxy solution, this Apache web server also has reverse proxy functions as an additional option to Apache and Nginx was originally designed for and was designed with a focus on reverse proxy capabilities.



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



Because "forward" along with "reverse" come with connotations of directionality and false comparisons to "incoming" as well as "outgoing" traffic the labels could be confusing since both kinds of proxy deal with requests and responses. The best method to differentiate between reverse and forward proxy is to examine the requirements of the app that you're developing.




Reverse proxy is an essential feature when you are creating a solution for serving websites on the internet. They serve as your web servers in any interaction with the internet.




A forward proxy is useful when it is used before clients for personal usage, or in a working environment. They are your client's proxy through any interaction with the internet.




Differentiating by use case as opposed to focusing only on common name conventions makes it easier to avoid confusion.



Conclusion



The article explained the meaning of a proxy with the two main types being the forward proxy and reverse proxy. Practical scenarios to use them as well as a discussion of most beneficial features were used to differentiate forward proxies from reverse proxies.
