History Of ORKUT
Some other Cool Facts about this guy:
History Of ORKUT
A guy lost his girlfriend in a train accident.... but the gal's name nowhere appeared in the dead list. This guy grew up n became IT technical architect in his late 20s, achievement in itself! He hired developers from the whole globe and plan to make asoftware where he could search for his gf through the web... Things went as planned... n he found her, after losing millions of dollars and 3 long years!! It was time to shut down the search operation, when the CEO of Google had a word with this guy n took over this application, This Software made a whopping 1 billion dollars profit in its first year, which we today know as ORKUT . The guy's name is ORKUT BUYUKKOTEN. Yes it's named after him only. Today he is paid a hefty sum by Google for the things we do like scrapping. He is expected to b the richest person by 2009.ORKUT BUYUKKOTEN today has 13 assistants to monitor his scrapbook & 8 to monitor his friends-list. He gets around 20,000 friend-requests a day & about 85,000 scraps!!!

Hostile proxy and Open proxy
Hostile proxy:
Proxies can also be installed by online criminals, in order to eavesdrop upon the dataflow between the client machine and the web.All accessed pages, as well as all forms submitted, can be captured and analyzed by the proxy operator.For this reason, passwords to online services (such as webmail and banking) should be changed if an unauthorized proxy is detected
Open proxy server:
proxies might be used for abuse, system administrators have developed a number of ways to refuse service to open proxies. Many IRC networks automatically test client systems for known types of open proxy.Likewise, an email server may be configured to automatically test e-mail senders for open proxies .

Intercepting proxy and Forced proxy
Intercepting proxy :
An intercepting proxy (also known as a "transparent proxy") combines a proxy server with a gateway.Connections made by client browsers through the gateway are redirected through the proxy without client-side configuration.Intercepting proxies are commonly used in businesses to prevent avoidance of acceptable use policy, and to ease administrative burden, since no client browser configuration is required.It is often possible to detect the use of an intercepting proxy server by comparing the external IP address to the address seen by an external web server, or by examining the HTTP headers on the server side
Forced proxy:
The term "forced proxy" is ambiguous. It means both "intercepting proxy" -- because it filters all traffic on the only available gateway to the Internet .
and its exact opposite,non-intercepting proxy"-- because the user is forced to configure a proxy in order to access the Internet.
Forced proxy operation is sometimes necessary due to issues with the interception of TCP connections and HTTP.This is primarily because the client thinks it is talking to a server, and so request headers required by a proxy are unable to be distinguished from headers that may be required by an upstream server.

Transparent and non-transparent proxy
Transparent and non-transparent proxy server:
The term "transparent proxy" is most often used incorrectly to mean "intercepting proxy" (because the client does not need to configure a proxy and cannot directly detect that its requests are being proxied)
A 'transparent proxy' is a proxy that does not modify the request or response beyond what is required for proxy authentication and identification.
A 'non-transparent proxy' is a proxy that modifies the request or response in order to provide some added service to the user agent, such as group annotation services, media type transformation, protocol reduction, or anonymity filtering

Caching proxy and Anonymizing proxy
Caching proxy :
A proxy server can service requests without contacting the specified server, by retrieving content saved from a previous request, made by the same client or even other clients. This is called caching. Caching proxies keep local copies of frequently requested resources, allowing large organizations to significantly reduce their upstream bandwidth usage and cost, while significantly increasing performance.There are well-defined rules for caching. Some poorly-implemented caching proxies have had downsides (e.g., an inability to use user authentication).(Known HTTP Proxy/Caching Problems)
Anonymizing proxy:
An anonymous proxy server (sometimes called a web proxy) generally attempts to anonymize web surfing . see above orkut proxy examples ie, act as a anonymizing proxy.These can easily be overridden by site administrators, and thus rendered useless in some cases.
Access control: Some proxy servers implement a logon requirement. In large organizations, authorized users must log on to gain access to the web. The organization can thereby track usage to individuals

Web proxy and Content Filtering Web Proxy
Web proxy:
A proxy that focuses on World Wide Web--WWW traffic is called a web proxy. Most proxy programs (e.g. Squid) provide a means to deny access to certain URLs in a blacklist.thus providing content filtering.This is usually used in a corporate environment, though with the increasing use of Linux in small businesses and homes, this function is no longer confined to large corporations. Some web proxies reformat web pages for a specific purpose or audience e.g., cell phones and PDAs.
Content Filtering Web Proxy:
A content filtering web proxy server like SafeSquid or DansGuardian helps distribute Internet access while providing control to the administrators over the content delivered.A content filtering proxy must necessarily accommodate the demands of granular rules for Internet access privileges and restrictions across an enterprise.A content filtering proxy may support authentication, to control access to the web.It usually produces logs, either to give detailed information about the URLs accessed by specific users, or to monitor bandwidth usage statistics
