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.
