What is the main purpose of a proxy server?
Imagine that for some reason you have to appear in court. It’s not that you have committed a crime or broken the law in any way, but you still have to show in the courtroom as a citizen of your country and be legally represented.
To appear more serious and legitimate in court, it is best to be represented by a lawyer. They are experienced professionals and can be of great help in your particular case. They are there to defend your rights and make your experience in court as pleasant as possible. Their role is also to make the judge perceive you as more legitimate, understand your arguments in a clear way, as well as respect you and your citizen’s rights.
Now, let’s use this metaphor to talk about a proxy server. In this case, your IP address would be you as a citizen, the court/judge would be the server that controls your target website and the lawyer would be the proxy server.
If your request to access the desired website is submitted through a proxy, you are much more likely to get to that website. You need the proxy server in order to appear more legitimate to the target website even if your IP address is completely in accordance with the Internet’s rules.
The main purpose of the proxy is to hide your IP address or original location from the internet hackers, monitoring your network traffic and surfing the web as a local. Even though we, at GeoSurf, do NOT encourage such actions, proxy servers (proxies) are used for both legal as well as unauthorized purposes.
As you can see, your IP is vulnerable and insufficiently strong on its own. It can get blocked or attacked, which will negatively impact your online experience. This can happen for various reasons, which we have already covered in one of our previous articles.
Why is a proxy server required?
Even now after you have read our story about the lawyer representing you in court, you might be asking yourself the following question: What is the purpose of using a proxy server?
A proxy server can be defined as a computer system or an application that serves as an intermediary between a person who browses the Internet and the server associated with his or her target website.
In other words, such a server acts as a transition between your personal computer and another server the purpose of which is to allow or prohibit your access to a certain website.
Now, in case this sounds too complicated, we will try to explain what is the use of a proxy server in a more simple way. This type of server will allow you to enter websites by hiding your true IP address from your target website. It can also make your online session more secure and enjoyable. We will explain this in more detail in the next section.
How do you use a proxy server?
Now that you know why proxies are useful, we will list some specific situations when they might come in handy.
A proxy server hides your IP.
When browsing the web, your access to certain websites might be denied due to your IP address or location restrictions. In this case, a proxy will act as a bridge and mask your true address, making your target website recognize its address as your own.
It will block malicious traffic and websites.
Your proxy server will act as a wall between you and potential online attacks that might come from hackers or illegal websites looking to spread malware and other types of dangerous content.
It will log your online activity.
This might be very helpful if you regularly visit certain websites. A proxy server will recognize these as your favorites and make your access to them more reliable.
Should I use a proxy server at home?
Taking into account all the information that you have read so far, it is more than obvious that using a proxy server might be just what you need. Whether you want to use it for hiding your IP (which is the most common of all its uses) or any of the aforementioned benefits, we sincerely recommend that you try it.
Obtaining a proxy is very simple. The only thing you need to do is buy a proxy from an Internet Service Provider (ISP). We have various offers tailored to everyone’s needs and you will definitely find the one that fits yours. After a short time, you will get the number of proxies that you required and be ready to browse the Internet without having to worry about anything.

A reverse proxy that is set up outside the firewall as a stand-in for a Web server can protect sensitive information stored on that Web server that must remain secure, When someone on the Internet makes a request to connect to your company’s Web server, the request goes first to the reverse proxy server. The proxy server then forwards the request through a specific port to the Web server over the trusted network. The Web server relays the reply back over the trusted, internal network to the reverse proxy server. The proxy, in turn, rebuilds the data packets from scratch (as proxies do) and sends the retrieved information to the client as if the proxy were the actual Web server. If the content server returns an error message, the proxy server can intercept the message and change any URLs listed in the headers before sending the message to the client. This prevents external clients from getting a glimpse of the redirection path of any URLs that point to the internal content ovides an additional barrier for the internal network. Ihacker is more likely to be restricted to only the information involved in a single transaction, as opposed to having access to the entire data stores of the organizationunauthorized user is unable to connect to the actual Web or database server because only the reverse proxy server is allowed such access.
