A proxy server is a communication program or service that acts as an intermediary between two computer systems, that is, when we connect to the Internet, the proxy takes care that this connection is not direct for multiple reasons, so what it does is that we have to make the request to him and he is in charge of looking for the information.

This transmission is done with the appropriate IP address of the destination computer avoiding a direct connection, since it is responsible for hiding to avoid direct interaction, meaning that the information is sent to the proxy, it is responsible for searching your request, although they can work in two directions, proxy forwarding and reverse proxy. A proxy server has several functions that make it unique, some of these functions are: access control, traffic registration, restriction to certain types of traffic, performance improvement, anonymity of communication, among others.

As I mentioned earlier, proxy servers have one of their features to protect and improve access to web pages, since it saves them in the cache so that when searching for something, the response will be faster. But this is not all because it also increases security by avoiding malicious programs. Maybe you ask yourself And how do you know when a content is not an act? Easy, because your filter works in relation to your security policy implemented in the network.

The proxy can work anonymously hiding the IP address, delete cookies, banners, among others. In short, A proxy server is a computer that acts as an intermediary between a client and the server, when the user navigates through a proxy all the information is highly protected while offering greater speed at the time of opening any page if it was already stored by the proxy with prior notice.


To learn how to configure a proxy server and enjoy all these privileges, but I have news, the configuration depends on the browser you are using although the difference is very minimal and I am sure that with the steps that I will leave you will not go to lose and you will perform an excellent configuration.

  1. Browser tools
  2. Internet Options.
  3. Connections
  4. LAN configuration
  5. In address and port enter the proxy data
  6. Only check the Use a proxy server for the LAN box and the others remove it.

Preserves the content requested by the user to accelerate the response in future requests of the same information of the same machine or others. It is usually HTTP / HTTPS proxies accessing web content. This function is especially necessary in networks with precarious Internet access, although users often perceive it as an intrusion that limits their privacy to direct individual connections.

The proxy server provides a point from which many users’ web traffic can be managed centrally. That can be used for many functions in addition to the typical views above. For example, it can be used for the establishment of controlling the web traffic of specific individuals, establishing how the web servers from which the content is to be obtained will be reached (for example, the proxy can be configured so that instead of obtaining the contents directly, do so through the Tor network).
