DEVELOPMENT OF HTTP CACHING PROXY SERVER

Abstract
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, and 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, usually to view websites that are normally not allowed, such as game sites in school or work place.
A proxy acts as an intermediary agent between its clients and the servers which they want to access, performing functions directed towards a variety of purposes, like security, caching, etc, in its capacity as an intermediary. Specifically, caching HTTP Proxy Servers are intermediate servers, which maintain a cache of Internet objects like html files, image files, etc which are obtained via HTTP.

Munchausens Syndrome by Proxy

...Munchausen Syndrome by Proxy is one of the worlds most hidden forms, and therefore also least recognised forms of child abuse. The syndrome is a psychological disorder where the parent fabricates illnesses and symptoms in their child, resulting in unnecessary medication that is often over prescribed or overdosed, and sometimes even exploratory surgeries on the child. How many people know about this? Such a minority that it is easily forgotten and almost never detected by doctors, nurses and surgeons, but the friends and family of the sufferer and their victim who is their very own flesh and blood. Therefore, while most child abuse cases go straight to the police, being assault and such other common forms, awareness needs to be raised about this because not only are these children dying from fabricated sickness, but these crimes are committed on a regular basis and are in such clear view that nobody notices them. Munchausen's syndrome by Proxy is an important issue because it is a form of child abuse and there needs to be awareness raised. But although it can be easy enough to spot for some, who wants to accuse someone of this? When it comes to symptoms, they can either be hard or easy to spot, depending on the position you're in. The children usually don't respond, or respond oddly to treatment; have medical problems that don't add up with their history; become well when the parent is away have a deteriorating health either away from medical facilities or when the parent...

Muchausen by Proxy

...Munchausen By Proxy Anthony Conejos Taylor College Mrs.Brooks 2/26/2015 Anthony Conejos Munchausen By Proxy Munchausen is a mental illness, in which a person repeatedly acts as if he or she has a physical, emotional or psychological disorder when, in truth, he or she has caused the problems. People with factitious disorders act this way because of an inner need to be seen as ill or injured, not to achieve a concrete benefit, such as financial gain. They are even willing to undergo painful or risky tests and operations in order to get the sympathy and special attention given to people who are truly ill. Some will secretively hurt themselves to cause signs like blood in the urine or cyanosis of a limb. Cyanosis is the condition occurring when the blood supply is cut off to a particular part of the body and the skin takes on a dusky blue color. Factitious disorder imposed on self is associated with severe emotional difficulties. Originally called Munchausen syndrome, named for Baron von Munchausen, an 18th century German officer who was known for embellishing the stories of his life and experience. He was known to invent fantastic stories of his adventures, including his riding cannonballs and traveling to the moon. Munchausen by Proxy however is where a parent is in need to gain attention and does so by inflicting harm or illness on their child.

Proxy War

...In his article Proxy War, Author Michael Brus claims that affirmative action and racial discrimination are one in the same. He says that the main difference between the two is that affirmative action singles out minorities for desirable things while racial discrimination singles them out for something undesirable. to a certain degree, I can agree with him, but this debate is a lot more complex and is not as simple as white or black. Racial profiling is a very real problem, and many people have claimed to have experienced it, especially in the black and hispanic communities. Nobody should ever be judged or face discrimination by the color of their skin. But, opponents to the practice of affirmative action claim reverse racism towards white people. Affirmative action is a practice that is intended to promote fairness to minorities in this country by stating that individuals are created equally and they should not be judged by their race or gender. Using for an example jobs and university applications, minorities applicants should be considered as an acceptable choice as a white applicant. This is of course taking into consideration their background and experience. In other words,affirmative action is intended to give minorities that have experienced disadvantages an opportunity to succeed. Although this practice has good intentions, this is not what happens. While this practice is meant to support individuals, it is resulting in it being solely based on race. Imagine this......

Munchausen by Proxy

...History of Munchausen In the 18th century, Karl Friedrich Hieronymus also known as Baron von Munchausen (1720-1797) was known for his highly unlikely stories of adventure and escapes and being one of the most notorious liars in the century. In 1737 as a German soldier, he served in the Russian–Turkish war and returned with exaggerated stories of adventure. Every evening after supper in the banqueting-hall he would gather his friends and those in attendance and tell stories of his past. He loved the attention he received from the stories he would tell.His stories were so extreme and extravagant that an author named Rudolph Erich Raspe, who was seeking refuge in England from the German law, decided to write about the adventures of Munchausen.The first edition of Munchausen's tales that was attributed to him appeared anonymously in 1785 and was called Baron Munchausen's Narrative of his Marvelous Travels and Campaigns in Russia. Gottfried August Burger edited the first German version the following year. Rudolph Erich Raspe never claimed his rights over the success from his books. Some still debate whether Raspe or Burger actually published the first book about the tales of Baron von Munchausen. Munchausen’s tales are so outrageous; many of the stories attributed to him have appeared in French, Spanish, Welsh and Greek literature. (Heritage, 2013) Today his name is known for boasting, fabrications and exaggerated stories. Definition In 1951the name Munchausen made its way into...

Proxy Voting in Australia

...1. Process of Voting by Proxies Public companies at many times require resolutions to be passed by members. These resolutions are passed by holding general meetings. However, it is inconvenient for many members to attend the meetings, for example members maybe living abroad or in different states. In the absence of members, there is provision of proxy voting. Proxy voting means to appoint an individual or a body corporate (s 249X 1A) to vote in place of a member (Halsbury, pg 1). A proxy appointment form is sent to members along with notice of meeting. Members unable to attend the meeting then fill in the proxy form and send it back. The proxy appointed has the same right as the member would have in a meeting, to speak, vote or not vote and demand for a poll. However, a proxy is expected to act according to the instruction of the member or, if undirected, in the interest of the member (Halsbury, pg 12). Voting occurs either by a show of hands or a poll. A proxy can join a demand for poll and take part in it, however, a company’s constitution may restrict partake of proxies in a show of hands (Halsbury, pg 12). Yet, proxy voting has its own criticism. Appointing a proxy does not necessarily mean that they will vote, a proxy may decide not to vote (CSA, pg 4) thus the shareholders vote is not utilised. Moreover, a proxy who has been appointed by many shareholders may choose to cast vote of those shareholders, with whom his views match (CSA, pg 6). This is a......

Realism In The Proxy War

...describe the relationship between the USA and the USSR (Soviet Union) after the World War II. It is the period of time from 1947 to 1991 when ideologies of USA and USSR – which are capitalism and communism – clashed against each other. Also, both sides aimed for the hegemony position and power expansion. The dissolution of the Soviet Union marked the end of the Cold War, precisely on December 26th, 1991. The defeat of Soviet Union left the USA as a single hegemony of the world, making it the only super power country with no rival to be fight against for the title. It can be understood why there is no more direct conflict between the great powers. Although there was no direct war between the USA and the Soviet Union, “proxy wars” have been happening since then. Proxy war is a conflict which happen because it is incited by major powers without them actually engaged in it.

Mauchausen Proxy Seyndrome

...Munchausen by proxy syndrome (MBPS) is a relatively rare form of child abuse that involves the exaggeration or fabrication of illnesses or symptoms by a primary caretaker. Also known as "medical child abuse," MBPS was named after Baron von Munchausen, an 18th-century German dignitary known for making up stories about his travels and experiences in order to get attention. "By proxy" indicates that a parent or other adult is fabricating or exaggerating symptoms in a child, not in himself or herself. Munchausen by proxy syndrome is a mental illness and requires treatment. About MBPS In MBPS, an individual — usually a parent or caregiver— causes or fabricates symptoms in a child. The adult deliberately misleads others (particularly medical professionals), and may go as far as to actually cause symptoms in the child through poisoning, medication, or even suffocation. In most cases (85%), the mother is responsible for causing the illness or symptoms. Typically, the cause is a need for attention and sympathy from doctors, nurses, and other professionals. Some experts believe that it isn't just the attention that's gained from the "illness" of the child that drives this behavior, but also the satisfaction in deceiving individuals who they consider to be more important and powerful than themselves. Because the parent or caregiver appears to be so caring and attentive, often no one suspects any wrongdoing. Diagnosis is made extremely difficult due to the the ability of the parent...
