Basically, proxies are proxy servers, and a proxy server acts as a buffer between a computer and the things on the Internet which that computer accesses, such as web pages and FTP archives. When the computer makes a request for data or information from the Internet, that information goes first to the proxy server and from there to the computer.

They can thus be used to make sure that an individual’s computer does not receive any corrupt or harmful data from the internet. Like its very name suggests, it means that computers are basically using the Internet “by proxy” - that is, through something else entirely.

There are four main types of proxy servers, each of which serves its own specific function. HTTP proxy servers are the most widely used because every browser is capable of using this proxy server. SOCKS proxies are designed to work with almost any type of data on the web (TCP/IP protocol). However, a computer must be able to work with a SOCKS proxy server. When a computer or program can work with a SOCKS proxy, it must be classified as either SOCKS 4 or SOCKS 5. The third type of proxy servers are CGI proxies, which are also known as anonymizers. It can only be accessed through a browser and, as such, it is one of the simplest proxy servers to use. The last kind of proxy server is the FTP proxy, which is an extremely specific and specialized proxy, which will only work with FTP servers. FTP proxies can be used with file managers, download managers, and with browsers.

ed to unblock a blocked website at school, you can use a Web proxy to do this. You must initially obtain a proxy server. You can have a free Web proxy or subscribe to a professional proxy provider.

For free ones, you can just search for web proxies through Internet search engines. This will lead you to quite a lot of websites for proxies.

Some system administrators will block proxy sites, but there are always new proxies popping up on the Internet. This means you will never run out of proxies.

After you have a free web proxy to use, you can just easily key in the Uniform Resource Locator (URL) of the blocked website you want to go to. Just type in the URL into the address bar of the proxy and hit the “Go” button.

Afterwards, the Web proxy will open a new page. It has two frames. The top frame shows the address bar of the proxy site. Should you wish to go to a different website, you can just type the URL into the address bar again.

The bottom frame shows the blocked website. You should be able to effectively find a way around the block site using a web proxy unless the administrator of the website you are visiting has blocked the web proxy you are using.

Since some administrators may block some common web proxies and redirection services, you can just look for another Web proxy to try bypassing it. You should look for uncommon web proxies. The more uncommon and difficult to find the web proxy is, the lesser is the probability that a system administrator will locate such a Web proxy to block.

For a variety of reasons, schools often attempt to block the access of students to some popular websites. Perhaps doing this is a means of managing resources or a way of censorship. You, as an individual who needs to visit a blocked website, should consult your guardian or parent so as to ensure that the sites you intend to visit do not have harmful content or illegal features.

proxy would not oblige you to download or install any software if you want to visit sites such as Facebook that are blocked by the school or office. To look for proxies for Facebook, you can just simply search the Web through Internet search engines like Google or Yahoo!. You can find numerous websites that offer proxies compatible with Facebook. Choose one among them depending on what you want.

Once you have found a Web proxy, it would be easy and convenient to browse Facebook. On the main page, key in the Uniform Resource Locator for Facebook- www.facebook.com.

Afterwards, all connections and traffic coming and going to Facebook is redirected via the proxy. This makes it appear like the traffic is surfacing from the proxy server, hence finding a way around the filtering system that blocks Facebook.

These proxies can enable you to go to Facebook without disclosing information about yourself, your computer, and your Internet connection. With this, you can easily access Facebook and chat, share music, and videos. The proxy servers can also enable you to view Facebook profiles, blogs, surf the website for music, and post comments.

When you use proxy servers, the computer lets you hook up with the proxy in lieu of the website you want to visit. Because of this, the filtering firewall or blocking system will be able to locate only the connection.

Moreover, the proxy server, which may be anonymous or transparent, will make a connection to Facebook and retrieve the website. This allows your computer to evade being traced.

There are times that you may be obliged to utilize the proxy’s IP address as a replacement for the domain name. The IP address can be recovered by pinging the Uniform Resource Locator from the control prompt.

Proxy servers can enable you to browse through the Web with a high level of confidentiality, anonymity, and security. This is because when you access a website such as Facebook using the proxy server, information like your operating system, location, browser type, and IP address is removed and the proxy server website is traced as the computer that has made access instead of you who actually visited the website. This would aid you in promoting your security since it aids in Web browsing.

erver protects your privacy by being the ‘middleman’ between you and a real server. When you visit a website, it intercepts your requests to determine if it can manage your requests by itself. If it can’t take care of your request, the proxy server will send the request to the real server. Thus, it provides you with indirect access to real servers.

Since real servers can’t directly access your information (e.g. browser type, location, IP address, internet service provider), this information can be prevented from being discovered by the real server.

Proxy servers are used to avoid recognizing information from the requests of the user. These are called anonymous proxy servers. Nowadays, numerous anonymous proxy servers are already available on the Internet. You can find lots of free services.

With proxy servers, it is not only your IP address that is being protected. Making your computer and yourself more anonymous through the use of proxy servers is possible.

For instance, linking proxy servers can provide you and the real server with a higher degree of “separation”. This makes it more difficult for would-be attackers to track you down. Also, if you encrypt data right at the outset, you can have an advanced degree of protection.

Once data is received and before it is forwarded, a proxy server can effectively encrypt data. However, a proxy server that is receiving unencrypted data will make the data open to harm. Usually, free anonymous servers do not encrypt data. You may need to pay a little amount to avail this kind of service and this may be very well worth it for you.

If you want to utilize an anonymous proxy server, see to it that the one you will use is well known for the quality of its service (preferably with posted privacy policies).

It is very important to keep in mind that proxy servers can’t guard you from someone who can access the computer you are using (e.g. those who nose around you). In this case, you should ensure that you take the necessary steps to safeguard your data by clearing and deleting cache, search history, and cookies from your toolbars and browser.
