{We all|All of us} {use|utilize} {computers|computer systems} and {surf|browse} the {internet|web}, {even though|although|despite the fact that} {many of|a lot of|a number of|much of} us are not {familiar with|knowledgeable about|acquainted with} the {technology|innovation} or the {terminology|terms}. {Most of|The majority of} us {have|have actually} heard the word proxy, {but|however} we are {not sure|uncertain|unsure|not exactly sure} {what exactly|exactly what|just what} it {means|implies|indicates|suggests} and why we {need|require} it. It is a term in the network {technology|innovation} which {refers to|describes} a server that {acts as|serves as|functions as} a medium through which {demands|needs} from {clients|customers} are {passed on|handed down} to the sources.

{For example|For instance}, if you are {looking for|searching for|trying to find} something, like {a website|a site}, or a link, you {connect|link} to the server and it {supplies|provides} you with the service from another source. The {job|task} of a proxy server is to filter the {requests|demands} that {come from|originate from} {clients|customers}.

For this {purpose|function} it {may|might} {use|utilize} the IP address or the {protocol|procedure}. If the {demand|need} you have is {legitimate|genuine} and {validated|verified|confirmed} the server will {provide|offer|supply} it for you. The server {might|may} {change|alter} your {request|demand} or {provide|offer|supply} you with the {needed|required} {data|information} without even {waiting for|waiting on|awaiting} {a response|a reaction|an action}.
Free proxies
The {idea|concept} was {implemented|executed|carried out} for the {first time|very first time} in the {period|duration} when {distributed|dispersed} systems were still a novelty, and they were {used|utilized} as a tool that would {decrease|reduce} their {complexity|intricacy} and make them {simpler|easier}. Nowadays most servers are {connected with|gotten in touch with} the web and {enable|allow} you to {browse|search} the web {easily|quickly}.

There are {few|couple of} {different|various} {kinds of|type of|sort of} proxies and each of them serves {a different|a various} {purpose|function}. {Most of|The majority of} them are {only|just} sub-types of the forward type. The forward proxy is the most {commonly|typically|frequently} {used|utilized} one and it does {submit|send} the {requests|demands} from a network to the {internet|web} source.

The most popular forward proxy types are, the {free|totally free|complimentary} proxies. These servers are {available|offered|readily available} to {anyone|anybody} that has {a valid|a legitimate} {internet|web} connection and there are millions such servers on the {internet|web}. If the user {doesn't|does not} {want to|wish to} {reveal|expose} his/her identity, i.e. the IP address, they will {use|utilize} {a free|a totally free|a complimentary} proxy when surfing the {internet|web}.

Reverse proxy
The reverse proxies These servers are {often|frequently|typically} called surrogates. This server does {seem like|look like|appear like} {a regular|a routine} server to the visitors. They {send|send out} the {requests|demands} of the visitors to the sources. {Afterwards|Later on}, the {responses|reactions|actions} are {sent|sent out} as they are from the proxy server and not from the source.

These servers are {usually|typically|normally|generally} {placed|put|positioned} near web servers, and all of the {requests|demands} that are {supposed|expected} to come to those servers go through the web proxies. The term 'reverse' is {used|utilized} as an opposition to forward, {because|since|due to the fact that} the reverse server is much closer to the web server and it is {responsible|accountable} {only|just} for one or {few|couple of} web servers.

These proxies can serve more {purposes|functions}, and they are {often|frequently|typically} {used|utilized} to {accelerate|speed up} the {encryption|file encryption}. In order to {be able to|have the ability to} {encrypt|secure} {a website|a site}, the web proxy server {must|should|need to} have a Secure Sockets Layer (SSL). It can {also|likewise} be {used|utilized} as a balance for the load which is {sent|sent out} to more than one web server.

Another {way|method} to {enhance|improve|boost} your {internet|web} security is through {the use of|using|making use of} {performance|efficiency} {enhancing|improving|boosting} proxies. This is {designed|developed|created} to be able to {deal with|handle} {exact|precise|specific} {issues|problems|concerns} and {problems|issues} that links {might|may} {cause|trigger}. It is {commonly|typically|frequently} {used|utilized} to {ensure|guarantee|make sure} {a better|a much better} {performance|efficiency} of the TCP.
