Making Net-Surfing As Easy As Pie
It connects us to people all over the world.
It allows us to view information that we would otherwise have no access to.
Using it is probably easier than "easy as pie".
And one of the things that helps us access the Internet, is the proxy server.
A proxy is something like an intermediary between the computer you are using and the server that you are trying to access.
This concept becomes easier to understand once you think about how it works.
Suppose there is a website that is accessed frequently from a particular computer.
This site gets saved in the cache of the proxy.
So the next time that somebody tries to view that website, the page is pulled up from this cache.
The advantage of this style of functioning is that the process is speeded up.
This is because the proxy does not need to go to the real server of that website to view it.
The site has already been placed in the proxy server's cache.
Web proxies are proxy that limit their job to the Internet.
Sometimes web proxies are used to block websites that are provocative or offensive.
They also serve another, perhaps more important, function of blocking viruses that may be present on the webpages that are being viewed.
In fact, a number of organizations make use of proxy to perform these very functions.
A company could even block its employees from viewing a particular website by making use of a proxy.
Notably, the user himself is usually unaware of the work being done by the proxy.
There are many other kinds of proxy servers that are found on the Internet.
These include transparent proxies, split proxies and reverse proxies.
Open proxies are proxy servers that are popular with spammers and Internet Relay Chat users.
There is also something called an anonymous proxy.
This helps provide anonymity, and hence, privacy, to the user.
It does this by hiding the IP address of the user.
As a result, the number of junk mails and spam that one would otherwise get flooded with are considerably reduced.
It is good to use an anonymous proxy server because it keeps you protected from hackers.
There is a lot more to proxy servers than this.
But the next time you are able to quickly access your favorite webpage, I'm sure you'll be blessing your proxy server even while the page loads!
