A proxy server is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity.

A proxy server is a server that acts as an
intermediary for requests from clients seeking
resources from other servers. A client connects
to the proxy server, requesting some service,

resource available from a different server and
the proxy server evaluates the request as a
way to simplify and control its complexity.
3. Usefulness of Proxy
To keep machines behind it anonymous, mainly for security.
To speed up access to resources. Web proxies are commonly used
to cache web pages from a web server.
To prevent downloading the same content multiple times.
To log / audit usage.
To scan transmitted content for malware before delivery.

6. Geological Proxy
In the study of past climates, known as paleoclimatology, climate
proxies are preserved physical characteristics of the past that stand
in for direct measurements, to enable scientists to reconstruct the
climatic conditions that prevailed during much of the Earth's history.
As reliable modern records of climate only began in the 1880s,
proxies provide a means for scientists to determine climatic patterns
before record-keeping began. Examples of proxies include ice cores,
tree rings, sub-fossil pollen, boreholes, corals, and lake and ocean
sediments. The character of deposition or rate of growth of the
proxies' material has been influenced by the climatic conditions of the
time in which they were laid down or grew. Chemical traces produced
by climatic changes, such as quantities of particular isotopes, can be
recovered from proxies. Some proxies, such as gas bubbles trapped
in ice, enable traces of the ancient atmosphere to be recovered and
measured directly to provide a history of fluctuations in the
composition of the Earth's atmosphere.To produce the most precise
results, systematic cross-verification between proxy indicators is
necessary for accuracy in readings and record-keeping
7. Unblocked proxy
There are so many sites which are blocked, by using proxy you can
be able to access those sites. Like e.g
www.aabcdallas.org
Facebook.com(china)
Youtube.com
Google.com
Twitter.com
