Free Proxy Site

A proxy site is a web page that will allow you to access websites unhindered by restrictions and content filters. These sites enable you to bypass your own Internet Service Provider and browse through the proxy web site. Just type the web site address you would like to visit in the form they provide, and start browsing.
They not only allow you visit blocked sites; they also allow you to have online privacy. The website that you visit can detect your IP address and then use it to find more information about you. Free web-based proxy sites enable you to hide your IP address by acting as an intermediary between your computer and websites. When you use one of this, the websites you visit will see a different IP address that can't be used to track you.
These sites are one of three proxy tools. The other two are Desktop Software which requires downloading and installation; and Virtual Private Network (VPN) services which also require installation. Proxy sites are the easiest to use of the three, as no set up is required. The drawback however is that most of these sites have traffic limits and are easily blocked. Because proxy sites are so easily blocked there is a constant need for new ones. As such there are numerous websites from which users can source and keep up to date on active free proxy sites.
Proxy lists are the easiest way to keep track of free proxy sites. However be careful in getting the right list as there are some proxy lists that do not have legitimate, updated and fresh lists. A genuine proxy list contains a list of proxies that are new and have constantly been maintained and updated for its users.
The best way to find a legitimate proxy list is to check on the credibility and do random checks of the proxies in the list. It is therefore wise to bookmark a proxy list and check it regularly for updates on your favorite proxies. This also makes them easily available when the need to use them arises.

Proxy Top List - Finding the Proxy Servers That You Can Trust

How do you choose a proxy especially if you are relying on a proxy to connect to any websites like the social networking websites that are banned by your school or organization? Since there are many companies and online advertisement that offer the best solution, do you know which one to choose?
There are many websites that offer proxy top list but you cannot totally rely on the information provided by these sites. For one thing, the information and details on these sites need to be frequently updated. You might be relying on outdated information if you are not careful enough. Another thing is that the list might be provided for some reasons like promoting their own servers without us knowing it. Moreover, it is very difficult to determine the validity of the information that is provided on the websites.
One of the most popular search results are those offering the free service. As we are all aware (even if you are not, think this over), proxy runs on servers. Usually there are some costs involved in running a server and a free service is too good to be true. Therefore, there is a strong reason to doubt free proxy servers. The word 'free' is normally used to attract or should I say to fool people into getting something extra like malware that can damage your computer.
Therefore it is advisable to do some research on the reputation of advertised proxy servers. Try searching for more information from the Internet and forums. See what you can conclude based on other people's comments. You might also consider reputable companies compared to companies that are not well-known that offer similar services.
You may need to do extra work for this, but as the saying goes -- "better be safe than sorry".
At the end, I'd like to share cool websites with more information on topics like Proxy Sites and how to find Proxy Sites. Visit for more details.

What is a Proxy Server?

What is a Proxy Server?

A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server, then requests a connection, file, or other resource available on a different server. The proxy provides the resource either by connecting to the specified server or by serving it from a cache. In some cases, the proxy may alter the client's request or the server's response for various purposes.

Web proxies

A common proxy application is a caching Web proxy. This provides a nearby cache of Web pages and files available on remote Web servers, allowing local network clients to access them more quickly or reliably.
When it receives a request for a Web resource (specified by a URL), a caching proxy looks for the resulting URL in its local cache. If found, it returns the document immediately. Otherwise it fetches it from the remote server, returns it to the requester and saves a copy in the cache. The cache usually uses an expiry algorithm to remove documents from the cache, according to their age, size, and access history. Two simple cache algorithms are Least Recently Used (LRU) and Least Frequently Used (LFU). LRU removes the least-recently used documents, and LFU removes the least-frequently used documents.
Web proxies can also filter the content of Web pages served. Some censorware applications - which attempt to block offensive Web content - are implemented as Web proxies. Other web proxies reformat web pages for a specific purpose or audience; for example, Skweezer reformats web pages for cell phones and PDAs. Network operators can also deploy proxies to intercept computer viruses and other hostile content served from remote Web pages.
A special case of web proxies are "CGI proxies." These are web sites which allow a user to access a site through them. They generally use PHP or CGI to implement the proxying functionality. CGI proxies are frequently used to gain access to web sites blocked by corporate or school proxies. Since they also hide the user's own IP address from the web sites they access through the proxy, they are sometimes also used to gain a degree of anonymity.
You may see references to four different types of proxy servers:
  • Transparent Proxy

    This type of proxy server identifies itself as a proxy server and also makes the original IP address available through the http headers. These are generally used for their ability to cache websites and do not effectively provide any anonymity to those who use them. However, the use of a transparent proxy will get you around simple IP bans. They are transparent in the terms that your IP address is exposed, not transparent in the terms that you do not know that you are using it (your system is not specifically configured to use it.)
  • Anonymous Proxy

    This type of proxy server identifies itself as a proxy server, but does not make the original IP address available. This type of proxy server is detectable, but provides reasonable anonymity for most users.
  • Distorting Proxy

    This type of proxy server identifies itself as a proxy server, but make an incorrect original IP address available through the http headers.
  • High Anonymity Proxy

    This type of proxy server does not identify itself as a proxy server and does not make available the original IP address.
