Proxy Server Types

• Web proxies

Web proxy is a commonly used proxy application. The file and web pages available on the remote web servers are provided through the nearby cache. In this way, local clients can access the information more reliably and quickly.

A web based proxy server looks for a URL in local cache when a specific web resource or URL is requested. The document is returned immediately if it is found on the local cache. In other cases, the server requests the page from the remote server and then returns it to the client and saves a copy in the cache. An expiry algorithm is used to delete the documents from the cache depending upon the access history, size and age. Least Frequently Used (LFU) and Least Recently Used (LRU) are the two expiry algorithms that are used in this case. Least frequently used documents are removed by LFU while the least recently used documents are removed by LRU.

CGI proxies are special web proxies. These are special types of websites that allows clients to

Public Proxies

Public proxy servers are visited by millions of people everyday. The typical users are

  • College students who want to bypass school firewall filters to visit sites like Facebook or MySpace.
  • Corporate staffs who want to open external websites that blocked by company network.
  • Individuals who have concerns about their online privacy and want to hide their IP address.
  • Persons who want to access web contents or streaming videos only available for certain countries.
  • People who want to speed up their network connections to specific websites.

Believe it or not, most of public proxies are free to use.

On the other hand, you may see some advertisements on their sites, such as Google Adsense, Ad Banners, or Pop-ups. Through those Ads, a well-built proxy site with decent traffic often generates more than enough money to cover its operating cost. Nevertheless, as an end user, you don’t need to pay a penny to access most of public proxies.

You may get a daily list of fresh proxy sites through:

  • Proxy List
  • Free Web Proxies
  • Google Web Proxies Group
  • Yahoo Web Proxy Group

Anonymous Proxies

Anonymous proxies are designed to protect the anonymity and privacy of web browsers from site operators, hostile governments and internet snoops. The software for anonymous proxies is situated on the proxy server.

In anonymous proxies, the web browser is connected to server, which then connects to the online server. The web server is unaware of your identity. It is only aware of the identity of the server. As the proxy server can’t ascertain your presence – you need to select a trustworthy proxy server.

Features to Watch Out For

Good web proxies permit the user to set up an SSL or TLS tunnel. This prevents packet sniffers from eavesdropping while surfing anonymously.

Some anonymous proxies support HTTP while others support FTP. On the other hand, higher grade anonymous proxies support HTTPS. Select anonymous proxy servers which support the protocol you intend to use.

An anonymous server, in addition to hiding the IP address, also removes traffic such as scripts, banners, pop-ups, cookies and referrer information. These options must be configurable by end users to enable proxy

Proxy Script

In recent times, hackers are always attempting to gain and steal knowledge and personal information. This is why your anonymity is very important. Proxy sites are the sites that allow users to anonymously browse the Internet, without a hint or trace of where they have been, or who was viewing the page. Proxy sites are powered by different kinds of a proxy script. A proxy script is the type of script needed to run a proxy site. There are many different kinds of proxy scripts out there which are available free to use. The popular PHProxy and CGIProxy have both proven themselves to be the most popular of the sort so far, but recently, a new web proxy script has appeared on the web.

The name of this new web proxy script is called Zelune. Zelune has self declared itself the fastest web proxy ever made! If you do not believe this, or have never seen a zelune proxy in action, I highly suggest trying it out for yourself. The special thing about Zelune is that it uniquely uses a special cURL proxy script to download pages. What exactly does all this mean, and how is this

Server Proxies

Server proxies store frequently accessed resources that speed up the load time and saving bandwidth.

Server proxy content filtering, used in countries, businesses and schools, restrict access to certain sites and pages by using blacklisted site database or flagging sites that contain specific keywords.

Salient Features

Server proxies who circumvent override the content filtering proxy instructions for gaining access to blocked sites. Often, web tracking is tracked by search histories and IP addresses of inspecting visitors. Few proxy servers enable users to hide their IP address behind proxies to anonymously browse the web.

As anonymous web proxies permit browsing anonymity, hostile proxies eavesdrop on web browsing of the user. Before hitting the website, most reverse proxy servers send online requests through proxy.

As the traffic passes through, proxies encrypt the information, including password, before passing them into website.


Server proxies are firewall mechanized which substitutes a protected host network’s IP address with temporary addresses for data traffic. It makes decisions for authenticating the client or user’s IP address to establish connection to remote computers.

Server proxies act as intermediary or interface to connect two or more computers having different

Various Aspects of Proxies

Caching proxy server, web proxy, content filtering web proxy and anonymizing proxy server are some of the kinds of proxies that are commonly accessed by computer users. Aside from these servers, the other types include the hostile proxy, intercepting proxy server, transparent and non-transparent proxy server, forced proxy, suffix proxy, open proxy server, reverse proxy server and tunneling proxy server. Furthermore, some work places and schools use a specialized kind of proxies known as a content filter, in order to avoid unauthorized requests and access to the Internet and other networks that usually store private and confidential data.

Proxy sites are web pages that allow computer users to browse the Internet without using the services offered by their Internet provider. They allow people to access web resources without revealing the Internet Protocol address of a computer system that they use. They also enable users to bypass content filters like WebSense and SmartFilter. To avoid having problems related to the use of these sites, it is important to prevent accessing the same site for several times. In addition, it is necessary to visit web pages that regularly update their proxy lists. Moreover, users should know the particular regions

Facebook Proxy

Facebook has been blocked by schools and work places for some time. This isn’t a recent occurrence. In fact, many sites are blocked by schools (mostly social networking sites) and Facebook is not the only victim of schools and work places blocking sites that some deem as unproductive. To gain access to Facebook you will need a proxy. Through the use of a proxy you will once again be able to access Facebook without your schools or workplace knowing. This is how a majority of other users who are also blocked from Facebook at school or work manage to access it without a problem.

There are two kinds of proxy servers that will give you access to Facebook. The first and most common is a web proxy. These proxy servers appear as simple websites and are the most predominant kind. There widespread availability is because they are extremely easy to setup. To use a web proxy to access Facebook you simply load up the web proxy page and then type in the Facebook url address. No software or user registration is required for web proxy sites. The second kind of proxy that you can use to access

Proxy Address Settings

The settings determine what web sites you are able to view, and which ones are blocked. It also can block certain email accounts and emails from being received. If you are on a large network of computers, and need to find a way to gain more access for yourself or a group of users, there are ways that you can bypass the proxy settings.

Each network has different settings that are installed to ensure that the information will be kept private and not be accessed by unauthorized users. When companies set up these kinds of settings, it can limit the amount and content of web sites that you are able to view.

While a certain level of protection needs to be in place, there may be a lot of web sites that you want to access that are secure, and do not have negative content. In order to get access to these web sites that are being blocked on your network, you need to have administrator rights to change the proxy settings. This will enable you to use the Internet more effectively, to meet your needs. But possessing administrator rights has inherent dangers. By changing the

Unblock Myspace

A proxy web page also helps to hide whatever activity or content you may be looking at throughout a blocked web page. It is sort of like being invisible while looking at a blocked web page. You can find any number of proxies just by doing a simple search on the internet and choosing one that works for you.

When you visit a proxy website, you can just type in the website that you want to view, and it will load from there. Different types of proxy sites will either allow you to view the full site or a limited version of the site you need to view. If you are trying to unblock a site that you want to view videos on such as YouTube, you may have a bit of trouble finding the right proxy, but if you keep searching you will find what you need. Many government owned computer networks will most likely only allow you to view limited parts of pages you are viewing.

The best way to actually seek and find a decent proxy site is just by doing an internet search and browsing through various sites that offer proxy sites.

Secret Surfing

We will firstly cover the anonymous browsing section, the IP address of any computer is recorded when you go onto a site. Your IP basically represents, or is as equivalent as your home address. People can automatically trace where you are located, with your specific IP.

Web based proxies eliminate this problem by using an anonymous IP, there fore you can surf on the internet as much as you like, without getting it tracked back to your home. There is nothing to install on your system, all you basically have to do is enter your URL into the address bar of the proxy.

The second use of proxies are used for accessing blocked sites at your work or education place. As the web 2.0 bubble grows a lot of people try to access sites such as Facebook or Myspace, this causes them to do less work and spend more time socialising. Although employees and schools can block out these sites, they can not stop all of the existing proxies. Therefore, a major source of traffic for these proxy sites are coming from these specific locations.

If you own a proxy yourself, you will notice that

Private Proxies

As a result of IP, online scammers and hackers can trace your pc and remotely access it without your permission and without you realizing it. Chances are the financial information for example your bank details (card number, pin, social security number, etc) could be hacked by these folks. Sure you don’t want this to happen.

This is how proxies seem sensible. A web proxy is sort of a middleman that hides your IP in the remaining portion of the internet players. So when you go to a website, before your pc sends out request for access, you initially send your IP address to a proxy understanding that proxy server sends your request to the website. Subsequently, the website provides information back to the proxy then for you. Through this, you are protecting your personal computer from any online threat made by hackers and scammers. There’s two types of proxy- the free as well as the private (which is usually paid) proxy. When you are looking at these proxies, you obtain everything you buy. Free proxies are extremely inconsistent and also since lots of people rely on them, they are slow and downtime is very common. Alternatively, private

Stealth Surf Proxy

Have you ever wondered why people give away free things on the internet ? Ever wondered why those kind people will cripple their servers by allowing ever anonymous hunting stealth surfer on the planet to surf using their proxy?  Well if you’re curious I’ll tell you.

That’s right most of the time, the owners of the servers are completely  unaware that  their server is being used as a free anonymous proxy.  A simple misconfiguration on their server and they’ve opened it up for everyone to use.   All those fine people worried about their anonymity are generally stealing someone else’s bandwidth as they surf.   Of course most aren’t aware of this and they’ll happily recommend to their friends and the server will get slower and slower.

Sure you’re leeching a service off some system for free, it may be extremely slow but at least you have some anonymity.  Much better off than the folks who stumble upon one of the other types of free anonymous proxies – the nasty little hackers honeypots.  That’s right the anonymous proxies deliberately set up (again usually on hacked servers) to get people firing all their html traffic across.  

Internet Censorship

A Proxy Server services requests from clients by forwarding requests to other servers.
If you are computer “C”, and you want to access server “S” but it is blocked, point your client’s web browser to Proxy Server “P”.

Thus C -> P -> S

An example of such a site is (ignore the pop-up windows) but if you search the web for proxy servers, you can have a list of thousands. Some are even more specific on what services you want enabled or disabled, such as removing JavaScript, enabling cookies, or displaying images.

As long as your network connection’s ISP isn’t blocking the Proxy Server, you can get access to those sites. And some get creative by using another standard HTTP port 80. Ports 8080 or 8081 are the most common, so you would enter for the URL.

A Circumventor is a Proxy servers used for defeating blocking policies implemented by an organization or country when “censorship” blocks access to certain sites. Of course, having a known list of proxy servers beforehand would be really helpful if you are planning a trip to such countries with censorship.

On the other hand,

Info of Proxies

Depending on your technical knowledge, you probably know that every computer on the Internet has a unique designation assigned to it when it connects online. It is called an IP address and it’s basically a series of numbers and decimals that signify which Internet provider company you use for Internet access, what country you’re in and even what city you’re located in. Why is it necessary to have such sensitive data on something so easily available? Well, it’s just a basic precaution. If we could compare it to something, we would compare it to fingerprints. If someone commits a felony, they can often be tracked to the crime by fingerprints. An IP address is a virtual fingerprint that links a user account online to an actual existing individual. It’s very handy, but it can also be potentially exploited. To prevent the risk of IP address misuse, proxies are available for everyone to use. A proxy basically makes sure that your IP address can’t be so easily detected.

Proxies are basically used through proxy servers which have their own IP addresses. In short, whenever you use a proxy server, you use their IP address. You still retain your

Must know about Proxy Templates

The development of proxy servers has a technological advance over these restrictions. These proxies let you access websites from restricted locations and are a source to bypass secure sites from blocked locations, as they have the ability to bypass the network firewalls and filters. These proxy servers enable the users to surf the internet from blocked servers and are compatible to surf through sites which have audio and video streaming platforms like Youtube.

Another advantage of a proxy server is that the chance of getting virus, spyware and other malicious scripts is reduced, and as a result your computer becomes a safer and reliable machine.
A lot of web sites offer the proxy servers and most of them provide proxy templates as well. Designing a proxy template is not an easy task. Considering this fact, a lot of websites offer pre-designed proxy templates for you. These proxy templates can be downloaded and are simple and easy to use.

The downloaded proxy templates are free of cost, but most of the host websites may require you to back-link to their websites. PHP and CGI proxy templates are also available on such websites. The downloaded files for the

Dangers of Using Proxy

Basically, a proxy is a collection of servers which allow you to access a website, while maintaining your anonymity by hiding your IP address. All information you wish to send to the website you are browsing passes through the proxy you use. Usually this information reaches the proxy in an unencrypted form, which means they can be easily read by the webmaster or the owner of the proxy. Such information transmitted may include your usernames and passwords and even banking information!

So, the first rule to follow when using a proxy is to never type in any information you wish to keep to yourself, such as your password, or credit card number. When checking your mail, or logging into your bank’s online banking system, never use a proxy. This helps in keeping all private information confidential.

When you first try a proxy website, be sure to read through the terms of service of that particular proxy. Proxies usually also have a privacy policy, which is also to be carefully read. If you doubt the integrity of the proxy site, never use the site. Only use proxies which are trusted by a lot of people, and have

Free Web Proxy

In many cases these proxy servers are used for increasing the network capacities and also its speed. This is done with the help of the saved information in the proxy servers’ database. It is also known that if a person searches something on the internet that required information will be stored in a special database called cache. When new users open the same page or ask for the same information, the proxy server looks first in his cache and only afterwards over the internet. In many cases the searched information was already opened and the proxy servers do not do anything but restore the information from the cache.

It is good to know that the most common used proxy servers are the anonymous ones. These servers hide your ID and any kind of information only in your interest. These anonymous servers also help in cases when some internet providers band users or regions or even countries. They can request the needed information with the help of these servers that help you browse without having to share your IP or ID.

Even if many persons consider web surfing a normal subject it is good to know that

Using a Proxy Browser

  • Keep the users and the machines behind it anonymous. Did you know that with every site you enter, you basically give away all your personal information such as passwords and usernames? This tool will provide no way for the user after you can to trace your Internet history easily.
  • Speed up your access to online resources. Sometimes, the most annoying part of surfing the web is to wait for it to buffer. These kinds of browsers are commonly used to cache web pages. These servers do this by delivering the requests quickly.
  • Censorship and Filtering. In schools and public computers, these browsers are utilized to filter certain websites or its content. This allows them to prevent their users from entering inappropriate websites. If you own a company, you cans use these browsers to prevent your employees from accessing sites that will cause them to waste time compromising your company’s output.
  • Accessing blocked sites from your school or workplace. This is one of the superficial but fun uses of these browsers. This function is just the opposite of what was previously mentioned. Most social networking sites such as Facebook and Twitter are blocked on universities and offices. With the help

Find Safe Web Proxies

Basically, a proxy server is just an ordinary web server, albeit one with a special function. This server lies between the web user and the sites they are visiting; with requests for web pages and files being relayed via this server. This relay means that it is the servers IP address which is reported to the site being visited rather than the IP address of the web user. Why is this important? IP addresses, particularly static IP addresses, which are more and more common with the expansion of broadband service, can be used to identify specific users. Just think about the implications of that for a moment.

It should be noted that not all proxy servers will hide this information which can be used to uniquely identify you from the sites you visit – there are anonymous proxy servers as well; these provide a higher degree of anonymity to you on the web. However, how can you tell which proxies are really protecting your identity? Read on for a few tips on how to find safe web proxies.

First, you can use the “whois” command if you are running any variant of Unix or Linux on

SSL Proxy

Many people just stop using the web as a good source to find information they need for work or school. The goal of proxies is to keep you anonymous online. A Proxy that uses the HTTPS protocol will be on the web with an SSL proxy that keeps you even more anonymous. The best proxy sites are CGI and PHP with SSL, they are the hardest proxies to block. Most sites charge money to use the SSL version but some are free. A web proxy is one way you can also get to social websites like Facebook and MySpace.

The Internet is full of proxy websites and most of them get blocked eventually. But those proxies that uses SSL you can still get to by going to there HTTPS address. For example: if you tried to go to a proxy bypass web-site and it was blocked then try going to it’s HTTPS protocol address. But you need to be careful not to use personal information when you surf through proxies. A proxy is like a web server that grants you access to the Internet through it. The same technology that administrators use to block you at school and work from getting to sites that
