Proxy: what is it for, when should it be used, how does it affect Network Security, Advantages, Disadvantages, where to buy?


You’ve probably heard of these terms that are so common on the Internet these days. But do you really know what a cache is or what a proxy is? These two concepts are essential for effective network management so that you can enjoy the Internet to its fullest without suffering any disruptions or service interruptions. It should be noted that if you are interested in high-quality proxies at affordable prices, we recommend visiting the following site –

For those who like to watch online series on the weekends, there is nothing worse than being offline, right? Therefore, throughout the article, we provide basic information about both terms. But, before starting, it is important to understand how to choose the right proxy for working on the Internet:

  • They should be inexpensive.
  • Allow you to visit prohibited sites.
  • Proxies must change the actual IP address.

What is cache?

In short, the cache can be thought of as a tool that allows you to load web pages faster while improving your web browsing experience. When a processor in a computer needs to send information to memory, it ends up spending a certain amount of time, the cache is used to pre-store that data and save that time.

The moment we access a particular website, the cache ends up copying and temporarily storing some information that has been downloaded and viewed by you. So the next time you access the same site, the cache will use that stored data to make the page load easier and minimize the number of requests to the server, increasing the access speed.

This mechanism is important not only for the user who browses faster but also for those who provide website hosting services who can guarantee their customers a quality service.

How and when to clear the cache?

Caching is our ally, but sometimes it can make navigation difficult. Over time, you gain access to a huge number of websites. If you go into your browser history, you will see that you don’t even remember visiting many of the pages on the list.

As a result, the cache is often filled with information that is not used very often, which can begin to degrade its overall performance. Another fact is the cache of outdated pages, which also has a bad effect on your browsing.

Ideally, you should periodically clear your browser cache. The time between each execution of this process will depend mainly on your amount of access. If you use the Internet a lot, clean it every week, otherwise once a month will be enough.

What is a proxy?

A proxy is a concept used in networks to define the intermediaries that exist between the server and the end-user. It works as a connection between an external (Internet) and local (i.e. your computer) network. The local addresses used by the computer are not suitable for external viewing: the task of the proxy is to send requests to the server, translate the responses, and deliver them to the computer.

All contacts made with the server must go through a proxy server and receive your IP address, the Internet Protocol, which acts as an identifier on the network and defines who you are. The proxy server masks your IP address so that your computer is not vulnerable to threats such as hacker attacks, for example, to improve security. It is also a proxy function to speed up web browsing as it can record visited websites in the browser cache.

There are free proxy services out there, but don’t be fooled. Most of them are just a decoy to gain access to your browsing data and use it to hack into your machine. If you decide to use a proxy, look for reliable services.
