If you are new to proxy, read the proxy definitions below. Hope it will help you to understand what is proxy server and how does it work.
- Permitting and restricting client access to the Internet based on the client IP address.
- Caching documents for internal documents. - Selectively controlling access to the Internet and subnets based on the submitted URL.
- Providing Internet access for companies using private networks.
- Converting data to HTML format so it is readable by a browser.
Some proxy servers let you cache internet documents for clients within the local area network. Caching documents means keeping a local copy of internet documents, so that the server doesn’t need to request them over and over again. Caching is more effective on the proxy server than on each client system. This saves disk space because only a single copy is cached. Caching on the proxy server means more documents that are often referenced by multiple browsers can be cached more efficiently. The system administrator can predict which documents are worth caching for a long time and which are not. It is easy to configure an entire workgroup to use the proxy server’s cache of documents. This reduces the load on the server by allowing it to get information from the cache when responding to subsequent client requests for the same data. Caching also makes it possible to browse the Web even if a Web server, or even the external network, is down, as long as one can connect to the proxy server. This improves service to remote network resources, such as busy FTP sites and transient Gopher servers that are often unavailable remotely, but may be cached locally. You can also cache a presentation you plan to present elsewhere when you are unsure of the location’s Internet capabilities.

A wingate is a proxy server that someone installs onto his or her computer which allows for multiple computers on a network to share a single Internet connection. Simple as that.
What are wingates used for? Primarily, wingates are used as an aid in FXP'ing files from one pub to another. FXP, or File eXchange Protocol, is a protocol that is mostly used by wingates only. However, a few other applications use FXP as well. Don't confuse FXP with FTP. They are completely seperate protocols. A pub is just a computer or a network. You'll often see things such as "...from pub A to pub B..." or similar when reading a document on wingates. Mentally, just say "...from system/network A to system/network B..."
The proxy server acts as both a server system and a client system. It is a server when accepting HTTP requests from browsers, and acts as a client system when its browser software connects to remote servers to retrieve documents. The proxy server uses the header fields passed to it by the browser without modification when it connects to the remote server. This means the browser does not lose any functionality when going through a proxy.
A complete proxy server should be able to communicate all the Web protocols, the most important ones being HTTP, FTP, Gopher, and WAIS. Proxies that handle only a single Internet protocol, such as HTTP, are possible, but a Web browser would then require access to other proxy servers to handle the remaining protocols. When a browser sends a request through a proxy server, the browser always uses HTTP for the transactions with the proxy server. This is true even when the user wants to access a remote server that uses another protocol; for example, FTP. Instead of specifying only the pathname and search keywords to the proxy server, the browser specifies the full URL. This way the proxy server has all the information necessary to make the actual request to the remote server specified in the request URL, using the protocol specified in the URL.
Anonymous (real anonymous!) proxy servers don't transfer the information about the IP-address of the client, and thus effectively hide the information about you and your surfing interests. Besides this, some proxy servers can also hide the very fact that you are surfing through a proxy server! Anonymous proxies can be used for all kinds of Web-services, such as Web-Mail (HotMail, Yahoo mail), web-chats, FTP archives, etc.
Interesting question.... The primary argument against open proxies is that their owners may not have intended for them to be used by the public. However, by running a service on a machine accessible to the public, without restricting access to that service, the machine's administrator is implicitly consenting for that service to be used by the public.
The internet is a public network. With regard to US law in particular, 18 USC 1030 (which covers computer-related fraud and theft) applies only when the user has knowingly accessed a computer without authorization or has knowingly exceeded his authorized access on that computer. Because an open HTTP proxy, by default, allows connections and use of the service by anyone in the world, the proxy's administrator has essentially "authorized" everyone to use the service. There's no intentional bypassing of security taking place.
There is a many internet pages where you can find proxy lists. But some
proxies are not working. For testing the proxies you can use "proxy checker" programs.
For example you may use Proxy Checker v 7 (www.helllabs.net).
Hell Labs Proxy Checker is a convenient tool for checking HTTP or Socks proxy
lists, it provides information that allows you to choose required proxy of the
Program is able to query following information:
- IP address/hostname of the proxy server
- Type of the proxy server (HTTP/SOCKS)
- Response time of the proxy server
- “Ping from Host” value
- Speed of the proxy server
- Location (country) of the proxy server
- Address, provided by the Whois service
- Description, provided by the Whois service.

Our proxy judges:
Proxy judges are simply .cgi scripts by which you can verify if a proxy is anonymous or not , it's nothing to do with the functioning of proxies nor with their connecting capabilities. There are 2 types of judges. CGI and AZ env controls variables which both can be used as externally and internally. Some CGI scripts is capable of giving levels to anon proxies as 1 to 5 which I don't think is necessary at all because a proxy is simply anon or not. Last ver. of cgi is V2.35. Its highly recommended to use AZ Env variables judges to get correct and fast information during proxy tests and last version is V.104. ... and... what makes a proxyjudge a proxyjudge... if it's opening in your browser, then its a proxyjudge!
By definition, a proxy is one who performs an action on an other's behalf. A proxy server accepts requests destined for a particular service and forwards it to the "real" service. Among other abilities, proxies can alter the appearance of the source of the request, or cache the results from the requested service so it can be used the next time something requests the same information. An open proxy is a proxy server left open for anyone who can find it to use as their own.
This type of proxy servers is called differently: CGI proxy, anonymizer (as the name of the most popular proxy server of this type is http://www.anonymizer.com/),web proxy etc.
Proxy server of this type represents (from user’s point of view) a usual web-page, very similar to pages of search engines. But instead of search phrases you should type into an input field the URL of that site which you want to look at. Then, having pressed the "Submit" button or "Go", you will get onto page, which URL you have specified to a CGI proxy. But address of this page (in the address line) from the point of view of your computer will be another, something like this:
http://www.cgi-proxy.com/http/www.your-url.com/path/ for example: http://www.cgi-proxy.com/http/www.yahoo.com/
Using such proxy servers, you can anonymously surf all over the Internet, without changing settings of your browser and without using any additional programs. CGI proxy supports HTTP and (sometimes) FTP and HTTPS protocols.
As for anonymity, CGI proxies are the same, as the HTTP proxies:
1. Transparent - these proxies are not anonymous. They, first, let a web server know that there is used a proxy server and, secondly, "give away" an IP-address of a client. The task of such proxies, as a rule, is information caching and/or support of Internet access for several computers via single connection.
2. Anonymous - these proxy servers let a remote computer (web-server) know, that there is used a proxy, however, they do not pass an IP-address of a client.
3. Distorting - unlike the previous type, they transfer an IP-address to a remote web-server, however, this address is a phantom: randomly generated by a proxy server or any fixed (not your) IP. So, these proxies distort your IP address from the point of view of a web-server.
4. High anonymous (elite) – they do not send your IP-address to a remote computer. Also, they do not inform that there is used any proxy server! So, a web-server "thinks” that it works directly with a client.
This anonymity classification is rather conventional. There are many other classifications, specifying / expanding / generalizing this one.
Unlike other types of proxy servers CGI proxies have considerably wider abilities as for information filtering. They can:
- Prohibit (or to leave only for itself, without passing to a client) cookie files
- Encode URL to which a request is addressed. For example, your request to the www.yahoo.com through CGI proxy in an address bar you will see something like that: http://www.cgi-proxy.com/abcd104dflsjuywe34sdfispd345klksfdsl So a system administrator viewing server logs with analysis purposes can not determine what server you have reached (www.sex.com or www.altavista.com).
Finding a site that allows you access to this script, is quite simple. As the filename of the script is normally nph-proxy.pl or nph-proxy.cgi, we can use Google to look for sites with pages matching this filename:
Another way of finding sites that allows you access to this script, is to search for the phrase "start using cgiproxy"
You will find that the first page might be no long active, blocked or require a subscription. Just go to the next page of results and you will soon find a page offering use of CGI Proxy or that links to another page offering access to CGI Proxy.
You cannot detect IP with the help of cookies. However, when you first visit a web site, your IP (i.e. your proxy server’s IP) is detected by the web server and then stored in the cookies. When you re-visit this site, the web server detects your IP again and checks it with the one stored in the cookies. If the IPs are not the same, the web server can “make certain conclusions”. Adn if you don’t disable cookies in your browser, no proxy will help you (anonymizers can disable cookies and stop relaying them to your machine).
They are special subprograms (scripts) run by the client’s browser. Therefore, no matter how hard you try to setup your browser (unless you disable these active scripts), you won’t be able to hide your real IP. These scripts are actually classified as simple programs and have very limited number of functions, however they are able to detect your IP as well as many other settings of your browser. Besides, these scripts can change your browser settings!
Java scripts have a many additional options (particularly, detecting or
changing your browser settings). In other words, Java programs can easily
detect your IP as well as practically all settings of your browser.
As far as it goes to protecting your IP from detecting by Java scripts, this is much more complicated: the most secure and probably the only way is to completely disable Java in browser settings, as long as Java has many network functions and it’s quite difficult to switch them all off.
There is a multilevel protection from these scripts. You can restrict a script from accessing your browser features. However, the best way of protecting your browser is to completely disable active scripts. You can disable scripts directly in anonymizers.
