7 Things About Proxy Sites That you want... Badly > 자유게시판

A proxy or proxy server is a software that acts acting as an intermediary for a client and server via the internet. Without the use of a proxy, users could send a request for resources directly the server, and the server will serve that resource to its user directly. This method is simple to grasp and use but the addition of proxies can provide advantages such as more performance, privacy and security, and much more. As an additional layer of passing through, proxies act as a safeguard for the internet between servers and clients.




It is generally accepted that the bundled combination of server hardware and the software to install proxy servers is usually called proxy servers. This article will focus on proxy servers that are typically described as software as and those used in conjunction with web servers. We will give a synopsis of the two main kinds of proxy servers, namely they are one that is forward and the reverse proxy. Each has its own specific usage which may be confusing due to a similar terminology.




This article will give you an understanding of what proxies and their subtypes are, and their utility in a variety of configurations. Through the article you will understand how to identify the scenarios that a proxy can be useful, and choose the most appropriate option for forward proxy or reverse proxy based on the situation.



Understanding Forward Proxies



Forward proxy also known by the name of an open proxy serves as a representative for a client that is trying to make an online request to a server. In this situation the entire attempt to send requests from the client is instead directed by the forward-proxy. The forward proxy, in its place as the customer will review the request. It will first check if the client been granted permission to send requests using this particular forward proxy. It will then reject an request and forward it to the original server. The client does not have direct access for the web. It can access only what the forward proxy allows it access to.




A common use case of forward proxies is greater security or privacy online. A forward proxy is connected to the internet instead of a client. in this process it utilizes an alternate IP address from that of the client's initial IP address.




Based on how it has been set up according to the configuration forward proxy can offer a range of features depending on how it's configured. This allows you to:




Beware of ad-tracker.


Circumvent surveillance.


Find out the restrictions that apply to the location you are in.




Forward proxies also are used in systems that use centralized security and -based access, like, in workplaces. When all internet traffic is routed through an open forward proxy, a administrator can restrict access for only a select user group to the internet through an common firewall. Instead of keeping firewalls in place for the client layer that may comprise several machines that have various environments and users, it is possible to have a firewall located at the front proxy layer.




It is essential to note the fact that forward proxy servers have to be set up manually for be utilized, whereas reverse proxy servers may be hidden from clients. Based on the type of IP address of the client, it is sent to the server that created it through forward proxy's privacy and security can be granted or kept hidden.




There are many options to be considered for forward proxies




Apache is a well-known open-source web server that provides forward proxy capabilities.


Nginx is another well-known open-source web server that has forward proxy features.


Squid is an open-source forward proxy that uses the HTTP protocol. Squid doesn't come with a complete website server software. We have instructions on how to set up Squid proxy to allow private connections with Ubuntu 20.04.


Dante Forward Proxy that utilizes the SOCKS protocol rather than HTTP and is better suited to use in instances such as peer-to-peer traffic. You can also understand how to configure the Dante proxy to allow private connections on Ubuntu 20.04



Understanding Reverse Proxies



A reverse proxy functions as a representative of a web server, which handles the incoming requests of clients on behalf of. Web servers can be a single server or a number of servers. It could also include an application server, such as Gunicorn. In either scenario the request comes from users on the internet generally. The majority of the time requests will get made directly to the server that has all the resources that the user is requires. However reverse proxy acts as an intermediary that isolates Web servers from direct interaction with the internet.




From the consumer's point of view, interacting with reverse proxy is not any different than interacting with an online server direct. It's pretty much the same but the user is unable to be able to discern the difference. The client requests the resource, and receives it without additional configuration needed to be completed by the client.




Reverse proxies offer features like:




A central layer of security that protects the server.


Controlling traffic coming inbound according to rules that you can establish.


A new feature for caching is now available.




While central security is an advantage of both reverse and forward proxies, reverse proxies provide this only to the server layer, but not the client layer. instead of maintaining firewalls at Web server layers, which could include multiple servers and various configurations, the majority of security measures for firewalls are targeted towards the reverse proxy layer. In addition, the ease of communicating with firewalls and interacting with requests from customers who aren't connected to web servers enables the firewall to focus on delivering the needs of their customers.




In the event of multiple servers operating within a reverse proxy it also manages controlling which requests go to which servers. A number of web servers could be operating from the same host and serving different kinds of resources or a mix of the two. These servers use the HTTP protocol just like a conventional web server. However, they can be equipped with other protocols for application servers like FastCGI. It is possible to configure reverse proxy servers to guide the clients to specific servers according to the type of resource they are looking for, or to follow certain rules regarding traffic load.




Reverse proxies are also able to gain advantage from their position ahead of web servers by providing caching functions. Large static assets are able to be configured using caching rules to avoid having to contact web servers every time you request. Some solutions offering an option to directly serve static files without having to connect to the web server even once. Additionally reverse proxy is able to handle compression of these assets.




The renowned Nginx web server can also function as an effective reverse proxy option. It is real it's true Apache web server is outfitted with a reverse proxy that is an additional option for Apache but Nginx was originally built for and is focused on the reverse proxy feature.



Differentiating Forward Proxy and Reverse Proxy Examples



Because "forward" and "reverse" are associated with the notion of directionality as well as false comparisons to "incoming" as well as "outgoing" traffic and can be confusing as both types of proxies process requests and responses. An alternative approach to distinguish between forward and reverse proxy service is to consider the needs of the application that you're working on.




A reverse proxy is a great option when you are designing a system to provide web-based solutions on the internet. They act as your servers for any interaction with the Internet.




Forward proxy applications are useful when they are placed in front of the user for personal use as well as in an office context. They represent your customers whenever you use the internet.




The use case-based differentiation instead of focusing on common naming conventions can assist in avoiding confusion.



Conclusion



This article explains the definition of a proxy along with two kinds: forward proxy and the reverse proxy. Practical applications and an exploration of the benefits were used to distinguish between forward and reverse proxy. If you're interested in exploring the use of proxy servers we recommend you learn how to configure Nginx as an internet server and reverse proxy on Apache running an Ubuntu 20.04 server.
