Types of Proxies

You will send your request to the proxy server, the proxy server sends the request to the internet, and then the proxy sends the request back to you. This process has many different means for use. Here are 5 types of proxies and their functions.

1. Web Proxy – A web proxy focuses on traffic over the World Wide Web. Many times these proxies are used by schools, countries, or corporations to block offensive web content, or to simply control their clients access to the internet.

2. Anonymous Proxy – Anonymous proxies are used to remove identifying information from a client request. An example of this would be a proxy that allows you access to Myspace while you are at work.

3. Caching Proxy – Caching proxies can send the client their request without contacting the remote server. It does this by using information that has been sent to the remote server before. This can cut down on time for requests sent.

4. Forced Proxy – A forced proxy server handles all of the requests from the client to the internet. Hence the name forced. Many times the client will not even know they are using a proxy.

5. Open Proxy – An open proxy is a proxy that allows anybody to connect to and use. Open proxies can also be exploited and misused by spammers. For this reason some websites will not allow traffic to their servers from known open proxies.

As you can see proxies have many benefits and can be used in various different ways. The best way to become familiar with proxies is to try them yourself so you may have a better understanding of what they do and how they work.

Free Proxy Surfing

Free proxy surfing is like a buffer between you and the web sites that you want to visit. It allows you to view as many information as you want on the Internet without the concern of being tracked. There are two ways that this can be accomplished: by using a program that can insure your anonymity or by using free proxy sites.

Free proxy surfing with the help of programs is a little more complicated and may not always work. On the other hand free proxy sites are very easy to use and can guarantee a very good result. Nowadays more and more people are using free proxy sites to surf the net. All one has to do in this cases is visit the free proxy site that assures your anonymity and enter the web site address, URL, of the page that you want to visit and remain anonymous at the same time.

How does this work? Well, when using a free proxy site to surf the net and remain anonymous at the same time, the proxy retrieves all the web sites before they are actually delivered to the person. This way, the other server will not see your IP address or other information, but it will see the anonymous proxy’ s address.

However, there are also some bad news when talking about free proxy surfing. Although, using free proxy sites sounds like a dream, there are also some downs that you should know about. When free proxy surfing, your browsing speed will slow down a little bit. Another thing is that there are many ads on these free proxy sites, that may drive you a little crazy at times. Moreover, there is always the chance that the actual proxy server record your data and a malicious server can find out everything about your machine. This can be avoided if using a free proxy server that is highly rated and also has a very specific privacy policy.

Info of Secure Proxies

Secure proxies are also used for screening purposes. This allows the administrator to contain access to undesirable or unwanted sites. Besides, secure proxy servers are also used for caching purposes, enabling faster access to frequently used sites.

Salient Features

These types of proxies work on the application layer – the seventh layer of the OSI model. Unlike firewalls which work differently on lower layers, secure proxies tend to stay application dependent.

These types of proxies aren’t easy to install and are highly difficult than firewalls simply because the functionality for every protocol application is configured one at a time.

Nevertheless, well-configured secure proxies enhance performance and security. With proxy servers functioning at OSI application layer, the filtering applications are very sharp. By inspecting messages, proxy web servers easily check URL addresses of outgoing web page requests.

Administrator Functions

Message function allows network administrators to bar access to few sites and permit access to others. Normal firewalls hardly check web domain names within messages.

The same way, for incoming data, ordinary routers filter by network address or port number. However, proxy servers also filter based on application content within the messages.

About Web Proxies Explained

A proxy is any software that supports the http proxy protocols. In it’s simplest form a proxy is a relay for data between two computers. A proxy is a intermediate server that forwards information between to points. A proxy is like a middle man, between the host, the server that you are trying to download files off, and you sitting in front of your computer. A Proxy is a central machine on the network that allows other machines in that network to use a shared Internet connection.Proxy servers can be configured to be light or heavy. Proxy servers are a bit like Swiss Army Knives: Just as the capabilities of a Swiss Army Knife extend beyond simple cutting, today’s proxy servers act as traditional proxies, but they also have a huge variety of security features. If you’ve ever accessed the Internet from an office environment,chances are your communications passed through a proxy. You may not already know what a proxy does. The only IP address an Internet host is aware of is the IP address of the proxy. There are further security advantages to using a proxy. A proxy will also typically have a cache of previous requests which can save bandwidth. A transparent proxy will intercept the client request, ensure that it is allowed, and then forward it on to the server. For every Internet application, there is a separate software proxy. The most common usage of a reverse proxy is to protect aweb server. When a user on the Internet requests data from a web serverprotected by a reverse proxy, the reverse proxy intercepts the request andensures that the data contained in the request is acceptable.

Proxies are capable of keeping you totally anonymous from hackers and logs. Proxies normally have a rather short lifetime, typically 12 hours. Proxies help reduce outside security threats while still allowing internal users to access Internet services. These protocols have an additional advantage in that they allow multiple proxies to share their cache information. We’ve seen proxies written multi-threaded to gain speed when their big speed loss was in cryptographic activity. The task of such proxies, as a rule, is information caching and/or support of Internet access for several computers via single connection.

Starting a Free Proxy

1. You can predict the reliability of your proxy

Since you are the owner of the proxy, you are aware of any technical issues that your proxy has to address. You can analyze the amount of bandwidth that your proxy site is using and you can come up with ways on how to set up your proxy so that it uses less of the server resources. As the administrator, you have a proxy that is ready to use when you need it.

2. You can earn some income through advertisements, referrals and membership

This is what most free proxy administrators do. If you have been using third-party proxy services for some time, you will notice that many of them have advertisements. There are some that sell banner space, while others use Google AdSense as their source of revenue. Some free proxies are also membership sites that offer more features if you get an account or join their mailing list.

You can also do those with your free proxy. That way, you can also get some income while investing time and money in maintaining the proxy.

3. It is free – well, almost

Initially, you will have to spend some cash for getting the domain and the hosting. You might also have to pay for the proxy script. But once everything is up and running, it wouldn’t cost you so much. In fact, if you already have your own hosting account, then (if your web host supports it) you can just add the proxy.

Private Proxies

Many large sized organizations have their own proxy server, as if they want an extra added security or if their organization necessitates extra browsing accessibility or whether they want more stability and reliability when it comes to internet connectivity. Other than that many organizations like to browse over private proxy just because of the fact that they want their browsing to be secure!

People prefer to go with private proxy more, as it allows browsing to be much faster and reliable. Normally a proxy’s life ranges from 12 to 24 hours because after that search engines ban that specific proxy, just for the protection of their system.

When one plans to buy a private proxy, he can surely find a great number of ways. All you need to do is to log onto the internet or search through the right search engine with the right keywords so you may get variety of options to choose from. There are a great number of internet based companies that use to sell such proxies to other people for their home or work use. However selecting the right company to buy a proxy is much as important as your safety does.

When buying a private proxy one should look deeply about his personal or business requirements. When buying any proxy when should look in the first place that whether it is compatible with SOCKS latest version as well as with HTTP, as these two are the diehard need for any web browser to access the internet. While selecting the right proxy provider you should look whether what is the total turn around time of these proxies and after how much interval their proxies are rotated.

Finding Best Proxies

* Ask your friends and co-workers

If you noticed that your colleague can access a website that you couldn’t view using your own computer, ask him or her if she is using a proxy. If he or she does, ask him or her what proxy it is. If that proxy works for them, it will most likely work for you, too.

* Browse blogs and websites that list and evaluate proxy sites

The problem with using proxies is that many of them tend to become unavailable after some time. For this reason, you have to know other proxies that you can use in case your top choice no longer works. Because of the increasing popularity of the use of proxies, many website and blog owners now dedicate themselves to giving the latest updates on proxies. You can also get advice from them on which proxies are the best. Sign up to their mailing lists so that you can get updates through your email.

* Search for the best proxies by using your favorite search engine

Your favorite search engine is still a reliable source of information when it comes to looking for the best proxies that you can use. Typing “proxy list” “new proxies” “reliable proxies” at the search bar of the search engine will give you a list of websites that can give you more information on proxies. Some proxy sites are also included in the search engine results.

Free Proxy Templates

On the web, there are a several websites which offer custom designed proxy templates, wherein you can make your own proxies using the proxy templates provided by them. They provide the required tools to design your own proxy websites in the form of downloadable zip files which comprise of all necessary files to make your own site. The zip folder consists of graphic files, images, fonts, Photoshop files and the script files. Also, in order to avoid any misuse, a config.php is attached which allows you to customize your website and design it your own ways.

These pre-designed proxy templates are simple and easy to use and can be downloaded from the host website for free. Some of these websites might ask you to link back to their websites, in order to be able to use the templates. PHP and CGI proxy templates should be fully up to date with the current version and are updated regularly in regards to any technological advances.

These free proxy templates can also be edited at a later point of time and the latest versions can be implemented into them to make them compete with the latest technology. When you make your website, the configuration files attached in the downloaded folder let you design your own site and edit the titles, Meta tags, keywords or any other text by altering the configuration file.

The development of proxy servers has overcome the technical barriers of not being able to access websites from restricted locations. Proxy servers not only enable you to access desired websites but also protect your computer from virus, spyware and any other malicious script. When creating your own proxy website using these downloaded free proxy templates; you may also wish to add the proxy template download link of the host website.

Basics Use Proxy

which processes the clients request and forwards it to the specified server. When we are connected to proxy server we can send a request for a webpage, file, connection or any of these resources available in other servers.

So then, how to use proxy? It’s quite simple. Proxy server comes in a numeric format, like 111.111.111.111.111. A proxy server allows you to hide the IP from the recently visited site; it acts as a middleman; where IP stands for Internet Protocol. Then with the means of a computer your request for a webpage will be carried forward to that particular website from your end and you will get to see the page right on the screen of your computer. You see, that’s how to use proxy server.

All the major Internet browsers allow the use of proxies including Internet Explores, Fire fox and many more.

It’s always better to learn how to use proxy as it is one of the safest ways of surfing on the Internet. Once you’ve learnt how to use a proxy you can maintain anonymity while browsing the Internet, you can hide your identity and you can also bypass the firewall of ISP and have a quick access to sites that have been blocked.

And you need to know to the different types of proxies and how to use proxy of every type. Along with the types you’ll need to learn how to use a proxy in the most appropriate way. Remember, when you learn how to use a proxy, you should also concentrate on finding the right proxy for use.

Proxies and Proxy Lists

Proxy Servers

One can go to the administrator and have the web content filter removed temporarily, but to have to go through this procedure over and over will be tedious. A far more convenient method is to use proxies on proxy servers.

Proxy servers, or websites, allow a user to overcome the website blockade. The process itself is not difficult to comprehend: what goes on is that once you are on a proxy server or site, you enter the address or URL of the blocked site. The site will be displayed in a separate window, and you will be able to access it as you would any normal web page.

Not only do you overcome the web content filter, but your IP address is hidden so that the website you are visiting will not be able to tell who is visiting it. The reason is that it is the proxy server’s IP that will be displayed, and not your computer’s.

Advantages of Using Proxy Servers

Aside from circumventing content filter applications, the proxy server has other benefits, one of them is that because the page being accessed does not directly interact with your computer or the network, there is less danger of having the security breached.

Another advantage is that by accessing the web page from a proxy server, the pages are cached on the proxy site. This is important because it makes retrieval of the page much quicker; instead of reloading a page, which can take time if the network or Internet is busy, the file is loaded from the cache instead.

Proxy Lists

This is very convenient for Web users, but unfortunately, due to its popularity, proxy servers can be difficult to access at times, and there will be some webmasters who will try to block proxy servers. The way to go around this is by going to a proxy list site.

There are several proxy list sites available, but the good ones should be regularly maintained; that is, the contents are updated on a consistent basis. In addition, the contents of the proxy list should also include proxy software, links to other sites, and other vital information.

Setting up a DMZ

As has been shown, there will be times when using proxy servers will be necessary. If you have a firewall, there is no need to disable it just so you can use a proxy. Instead, you can configure the firewall so that there will be a DMZ (demilitarized zone). This term is used to refer to that section of the network system that is not covered by the firewall.
