A proxy server is a filter that allows you to change the rules of access to a network such as the Internet, because of the risks that a “normal” connection can represent in certain cases. It can be used by professionals, but also by individuals. Without necessarily detailing its technical operation, here are the uses of a proxy.
A proxy is an intermediary between a client (ex: a computer) and a server (ex: a website).
Hide your IP address
The proxy is often used to obtain a certain confidentiality on the Internet: each visited website collects our IP address (e.g. that of the Internet box used), which makes us potentially traceable. With the intermediary of a proxy, it is no longer our personal IP address that is served, but that of the proxy. Discretion guaranteed. You can get fast free proxy options available now.
Bypass web censorship
Access to specific Internet sites may be prohibited in certain countries, either because the Internet is severely framed by a totalitarian regime, or because certain content is reserved for specific geographical areas (e.g. the replay of TV series to USA).
The use of a proxy then makes it possible to deceive a server targeted on our geographical origin: a French Internet user can for example provide an American IP address, thanks to the intermediary of a proxy.
Speed up the display of web pages
A proxy can cache the most frequently visited pages, which prevents them from being reloaded systematically when a user requests it.
For example, if a large company identifies certain sites as being very popular with its employees, it may decide to put the URLs (addresses) of those sites in the proxy cache. This will then make it possible to gain in performance, in terms of Internet or network access unless the sites in question are facebook.com, laredoute.com or vacances.com, but that’s another story. Unless it concerns the following point precisely you can make the full use of the same.
Block access to certain websites
A proxy also allows you to set up a blacklist of websites. For example, a company may feel that its employees have nothing to do with Facebook (yes, that’s debatable, but let’s admit): the URLs of these sites can then be designated as forbidden in the proxy settings, to encourage employees to do what they are really paid for!
But the reason we’ve used proxies in the past was speed. If you have several hundred people in an office, all of whom sometimes visit news, that page will download for each of them.
In short, the proxy is a device that makes it possible to personalize rules for accessing a network (eg Internet), or ensuring a certain confidentiality online. There are many free proxies to use (but how do you know if they are trustworthy?), Or the possibility of setting up your own proxy (which is a little more “tricky”). In both cases, you must then configure your Internet browser, to specify that you must now go through the proxy to display web pages.
