What is A Proxy Server

What is A Proxy Server

What is Proxy A Server? A proxy server is regarded as a computer that functions as a middleman between a web browser (such as Web Explorer etc) and as well as the Web. Proxy servers assist in improving web overall performance by saving up a copy of webpages that are frequently utilized. Whenever a browser requests a webpage stored in the proxy server’s collection (its cache), it’s supplied by the proxy server, that is quicker than going to the web. Proxy servers also help enhance security by filtering out some web content and malicious software program.

Proxy servers are used mostly by networks in organizations and businesses. Usually, people connecting to the Internet from home won’t use a proxy server.

Furthermore, in computer system networks, a proxy server is really a server (a computer strategy or an application) that acts as a middleman for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, internet web page, or other resource accessible from a different server and also the proxy server evaluates the request as a method to simplify and control its complexity. Proxies were actually invented to add structure and encapsulation to distributed systems.[1]Today, most proxies are internet proxies, facilitating access to content material on the World Wide Web and providing anonymity.

Types of Proxy Servers

Transparent Proxies
A transparent proxy, as the name suggests, is a proxy server that send your inquiry to the desired destination with out concealing or masking any of the info. This kind of proxy is often seen in business office networks, where there is no need to conceal the Internet protocol address of a Personal computer, given that every one of the Personal computers in the network are secure. Transparent proxies are just utilized as fundamental points of communication for all Personal computers in a network, and aren’t really the kind of proxy that people are thinking about whenever they shop for proxy server access online.

Anonymous Proxies
Anonymous Proxies conceal the data that goes through it, normally used to conceal the Internet protocol address of the Computer that’s using said server. This is extremely helpful for safe communications, especially along with government departments or large businesses that don’t want their valuable data to be stolen by harmful individuals. It is also helpful for common users just like us, because it safeguards us against hackers that snoop around for prospective victims via IP addresses.

Highly Anonymous Proxies
There’s another kind of anonymous proxy called Highly Anonymous Proxy. The real difference with this particular one is the fact that apart from concealing your Ip address, additionally, it conceals its presence so that the destination wouldn’t know that you’re concealing behind a proxy. To them, you’re simply accessing their server directly, and the Ip address that shows up may be like a personal IP Address instead of the obviously proxy IPs supplied by anonymous proxies.

Distorting Proxy
This kind of proxy server recognizes itself as a proxy server, but make an incorrect original IP address available through the http headers.

Reverse proxy
A reverse proxy is yet another typical form of a proxy server and it is normally used to complete requests from the web, via a firewall to separated, private networks. It’s used to avoid Web clients from having direct, unmonitored access to delicate information dwelling on content servers on an separated network, or intranet. If caching is allowed, a reverse proxy may also reduce network traffic by serving cached info instead of transferring all requests to actual content servers. Reverse proxy servers can also balance workload by spreading requests across a number of content servers. One benefit of utilizing a reverse proxy is the fact that Internet clients don’t know their requests are being sent to and dealt with by a reverse proxy server. This enables a reverse proxy to reroute or reject requests without making Internet clients conscious of the specific content server (or servers) on a guarded network.

A reverse proxy server will initially examine to ensure a request is correct. If your request isn’t correct, or not permitted (blocked by the proxy), it won’t continue to process the request resulting in the client getting an error or a reroute. If your request is correct, a reverse proxy may check if the requested data is cached. If it’s, the reverse proxy serves the cached info. If it’s not, the reverse proxy is going to request the info from the content server and provide it to the requesting client. It also caches the info for future requests.

Forward proxy
A forward proxy is considered the most common type of a proxy server and it is normally utilized to pass requests from an isolated, private network to the web via a firewall. Utilizing a forward proxy, requests from an isolated network, or intranet, may be rejected or able to go through a firewall. Requests can also be achieved by serving from cache instead of passing on the internet. This permits a level of network safety and lessens network traffic.
A forward proxy server is going to first check to ensure a request is correct. If your request isn’t correct, or not permitted (blocked by the proxy), it is going to reject the request resulting in the client getting an error or a reroute. If your request is correct, a forward proxy might verify that the requested data is cached. If it’s, the forward proxy provides the cached information. If it’s not, the request is distributed via a firewall to an actual content server which provides the info to the forward proxy. The proxy, in return, relays this info to the client and can also cache it, for future requests.

Proxy chaining
A proxy chain utilizes several proxy servers to help in server and protocol overall performance and network safety. Proxy chaining isn’t a kind of proxy, but a utilization of reverse and forward proxy servers across several networks. Along with the advantages to security and performance, proxy chaining permits requests from various protocols to be achieved in instances where, without chaining, such requests wouldn’t be possible or permitted. For instance, a request using HTTP is distributed to a server that will only handle FTP requests. To ensure that the request to be processed, it has to go through a server that will handle both protocols. This can be done by utilizing proxy chaining that allows the request to be passed on from a server that isn’t able to fulfill such a request (perhaps due to security or networking issues, or its very own limited capabilities) to a server that can fulfill such a request.

The very first proxy server in a chain is going to check to ensure a request is correct. If your request isn’t correct, or not permitted (blocked by the proxy), it’ll reject the request resulting in the client receiving an error or a reroute. If your request is correct, the proxy might verify that the requested data is cached and just serve it from there. Should the requested data is not in cache, the proxy will pass the request on to the next proxy server in the chain. This server also offers the capability to fulfill, forward, redirect, or reject the request. If it functions to forward the request then it too passes the request on to another proxy server. This procedure is repeated till the request gets to the last proxy server in the chain. The last server in the chain is needed to handle the request by getting in touch with the content server, utilizing whatever protocol is needed, to get the info. The details are then relayed back through the chain until it reaches the requesting client.

Top 10 YouTube Proxy Server Sites List Online 2016

Are you blocked from YouTube and looking to unblock them? Here, are top best YouTube proxy server sites list 2016 to use and permanently unblock YouTube censorship. So, if you are searching proxy server sites for YouTube, you have landed in the right place. They are not just the best in the proxy industry but also popular with reliable and unblockable servers.

YouTube

YouTube is a free video sharing website that lets people upload, view, and share videos. Videos can be rated, and the number of times a video has been watched is put on the site. At the moment, Google (a search engine company) owns and operates YouTube. Many different types of videos can be put onto the website. YouTube was started in February 2005 by three former workers of PayPal.

Reasons for banning and blocking of YouTubE

YouTube is blocked for a variety of reasons, including:
limiting public exposure to content that may ignite social or political unrest;
preventing criticism of a ruler, government, government officials, religion, or religious leaders;

-violations of national laws, including:
-copyright and intellectual property protection laws;
violations of hate speech, ethics, or morality-based laws; and
national security legislation.

-preventing access to videos judged to be inappropriate for youth;
reducing distractions at work or school; and
reducing the amount of network bandwidth used.

-In some countries, YouTube is completely blocked, either through a long term standing ban or for more limited periods of time such as during periods of unrest, the run-up to an election, or in response to upcoming political anniversaries. In other countries access to the website as a whole remains open, but access to specific videos is blocked. In cases where the entire site is banned due to one particular video, YouTube will often agree to remove or limit access to that video in order to restore service.

Businesses, schools, government agencies, and other private institutions often block social media sites, including YouTube, due to bandwidth limitations and the site’s potential for distraction.

Banning and blocking of YouTube in schools and some countries

As you know, YouTube is blocked in many schools because it allows children to search for videos online that would otherwise distract them from their lessons, much like how other social networking sites and game sites are blocked for the same purpose. But at a higher level than schools (and in workplaces), even some governments have blocked YouTube access to their country’s public, but their reasons can vary.

Iran
On December 3, 2006, the government of Iran blocked YouTube and several other sites in an attempt to stop films and music from other countries from being seen.

Turkey
Turkey blocked YouTube on March 6 2007 for letting videos that were insulting or discriminating to Turks and Atatürk, who is the founder of modern Turkey, to be shown, because of a “virtual war” between Greeks, Armenians, Kurds and Turks on YouTube, with people from each side posting videos to hurt the other. The video that caused banning alleged Turks and Atatürk to be ‘gay’. The video was first mentioned on Turkish CNN and the Istanbul public prosecutor sued YouTube for being mean to Turkishness. The court suspended access to YouTube while waiting for the removal of the video. The ban was strongly criticized. YouTube lawyers sent documentary of removal to court and users could access the website again on March 9 2007.

Thailand
During the week of March 8, YouTube was blocked in Thailand. Many bloggers (people who have a “diary” online) believed the reason YouTube was blocked was because of a video of the former Prime Minister Thaksin Shinawatra’s speech on CNN. However, the government did not confirm or give reasons for the ban. YouTube was accessible from March.

On the night of April 3, YouTube was again blocked in Thailand. The government said it was because of a video on the site that it said was “insulting” to King Bhumibol Adulyadej. The Ministry of Information and Communication Technology claimed that it would unblock YouTube in a few days, after websites containing references to this video are blocked instead of the entire website. Communications Minister Sitthichai Pookaiyaudom said, “When they decide to withdraw the clip, we will withdraw the ban.” Soon after this incident the internet technology blog Mashable was banned from Thailand over the reporting of the YouTube clips in question.

Brazilian model lawsuit and banning that came after
YouTube is being sued by Brazilian model and MTV VJ Daniela Cicarelli (better known as Ronaldo’s ex-fiancée) on the grounds that the site is making available a video footage made by a paparazzi, in which she and her boyfriend are having sex on a Spanish beach. The lawsuit says that YouTube has to be blocked in Brazil until all copies of the video are removed. On Saturday, January 6, 2007, a legal injunction ordered that filters be put in place to prevent users in Brazil from going to the website.

The effectiveness of the measure has been questioned, since the video is not available only on YouTube, but rather has become an Internet phenomenon. On Tuesday, January 9, 2007, the same court overturned their earlier decision, ordering the filters to be taken down, even though the footage was still forbidden, but without technical support for its blockage.

Morocco
On May 25, 2007 the state-owned company Maroc Telecom blocked all access to YouTube. There were no reasons given why YouTube was blocked. But the guesses are that it might have something to do with some pro-separatist group Polisario clips (Polisario is the Western Sahara independence movement) or because of some videos that criticized King Mohammed VI. This block did not concern the other two private internet-providers, Wana and Meditel. YouTube became accessible again on May 30th, 2007 after Maroc Telecom unofficially announced that the denied access to the website was only a “technical glitch”.

Australia
In Australia, some schools, including all secondary schools in Victoria, have YouTube blocked from student access, after fights have been posted on YouTube.

China
Currently in China the government has blocked YouTube. For several years it has been unblocked but since the past Five years it has been blocked.

With these and so many other reasons, YouTube has been blocked and continue to be blocked. And this makes it difficult to enjoy it’s great features as well as upload and videos share with friends online. Thus leading to users and many others looking for ways to unblock YouTube to continue their day to day social activities. As a result, proxy servers were born.

If you are one of those desperately in need of access to YouTube then the Proxy server sites listed below are the best for unblocking YouTube.

Top best YouTube proxy server sites online

Hidemyas is one of the most popular YouTube proxy server sites online that unblock YouTube with ease. HideMyAss is one of the biggest names on the market due to the great quality service they provide as well as the amount of free services that they provide. Unfortunately they are based in the UK and have had large issues with privacy in the past so if you’re looking for ultimate privacy we recommend looking at our logless or torrent list.

The company provides 860 servers with 310 locations across 190 countries – providing a possible 117,020 IP addresses – and this number is constantly growing. They also offer the three most common protocols: LLTP, L2TP and OpenVPN and easily allows you to change between them (depending on device).
They have software available for all major operating system and because they allow 2 simultaneous connections, something that’s not very common, you do not have to worry about which of your devices you wish to use at a given time.
On top of this they provide a vast range of free services through their website, which we will talk about later on in the post.

ExpressVPN prides itself on simplicity and security. With plenty of servers, impressive speeds and clean interfaces for all its software/apps, it’s definitely the No. 1 provider.

ExpressVPN is very similar to most providers out there, providing you with the three main security protocols and an extensive list of servers, in 78 countries to be exact. However, where it excels is in its dedication to making its software easy to use and streamlined. This can be seen all the way from its website to its mobile applications (which it has dedicated and optimized specifically). Also, unlike some providers, you’re able to set it up on multiple devices without any problems, although it limits you to two simultaneous connections (one computer and one tablet/smartphone).

IPVanish has definitely stepped up its game since our last review. Not only has it improved speeds and accessibility, but also implemented a true zero logs policy, which has made its security that extra step better.

Unsurprisingly, IPVanish is one of the top VPN providers available. It has a Tier 1 network of VPNs with servers in a whopping 59 countries, and major countries such as the UK and US have multiple servers to help deliver some of the best speeds in the business. It’s also one of only a few VPNs to provide VPNs in more exotic countries around the planet, such as Egypt and Panama.

Alongside this, it has a great team who provide top-end security and excellent customer support should you ever need it. It’s also implemented a full zero logs policy – not even connection logs – which is superb.

While simultaneous connections are allowed, this is slightly limited. In its words: “You can install our software on an unlimited number of computers or mobile devices and use 1 OpenVPN connection and 1 other protocol (L2TP or PPTP) connection at the same time.”

VyprVPN has been around since 1994 as part of the Golden Frog internet freedom consortium and from reading the review you’ll find out that even though they promise great things there are a number of issues with them.

VyprVPN is a pretty fantastic service with its great speeds, innovative apps, and a high level of customer support. As you’ll find out there is definitely some issues that they need to resolve though.

VyprVPN is brimming full of features. As mentioned below they have fantastic speeds and a dedicated privately owned network. Their network spans across 6 continents with 700 servers in 43 countries providing over 200,000 IP addresses.

Private Internet Access provide a comprehensive VPN service focusing heavily on user choice and security. Their Android app gives notably great protection for public WiFi networks, and the service is overall priced very reasonably indeed.

Private Internet Access is based in the US and is a subsidiary of London Trust Media Inc., a fact about which it’s refreshingly open. Servers are offered in 29 locations across 18 countries including the US, Europe and Australia, with nearly 3000 servers available in total. Users are allowed up to five simultaneous connections to the VPN from any combination of devices.

CactusVPN is a fairly small Moldova based VPN provider who gets a lots of things right. Its privacy policy is good (no usage logs), it uses excellent encryption, it proved very fast in our speed tests, and it is cheap (even for the more fully featured package). Add to this some great customer support, and that has the only VPN client we have come across to feature an Applications Killer, and we’re sold! This is not, of course, to say the service is perfect. Nothing is. Some logs are kept for 3 days, the policy regarding the number of devices that can connect at once is fairly limiting, and there is no option to pay anonymously. None of this however undermines the fact that CactusVPN offers a great little service and one that gets our recommendation.

CactusVPN has 16 servers in four countries: four in the United States, six in the United Kingdom, and a total of six in Romania and the Netherlands. You can subscribe to any one of these geographic areas for $4.99 per month, or gain access to all four plus CactusVPN’s SmartDNS service, for $6.99 per month. You can also purchase the SmartDNS service on its own for $4.99 per month. Discounts are available for longer billing periods.

Those who like to try before they buy will be pleased know that a 24 hours free trial is on offer, giving you full access to the range of services offered by CactusVPN during the trial period. While nowhere near as generous as that offered by some providers, this is still very welcome, and allows you to test the service out before handing over any hard earned cash.

IronSocket started out life as ‘HideMyNet.com’ (HMN), but has recently completely overhauled its services and rebranded itself. Despite perhaps a little too much honestly in its privacy statement (but for which we are inclined admire it), IronSocket provides an excellent all-round service with top grade encryption, a no usage logs policy, great performance results, and servers all over the world. The lack of custom software means that the experience is a little on the bare-bones side, but access to DNS Proxy, HTTP Proxy and SOCKS5 Proxy servers adds value to an already tasty package.

Overall, IronSocket provides a very good service. It is fast, uses excellent encryption standards, has servers just about everywhere (and growing), and is happy to let you P2P download where appropriate. We also admire its detailed privacy policy, although (and perhaps IronSocket is just being more honest than other providers) we feel the amount of detailed logs it keeps compromises its otherwise top notch privacy measures somewhat. It should be noted however that most so called ‘no logs’ companies also keep similar connection logs, and the fact that IronSocket is based in Hong Kong makes it immune to most forms of international legal pressure. Basically, we like it.

NordVPN is a Panamanian company with one of the highest dedications to security that we have seen here at BestVPN. It achieves this not only through it’s location but also through the technologies it provides. While this comes with a few downsides: primarily speed, it is a small price to pay for your personal privacy and protection.

NordVPN is a fantastic Panama based service with an extreme dedication towards security, as we outline below.

Their service has more than 80 servers across 28 countries covering all the major hubs in all the continents. They allow you to have up to six simultaneous connections with no restrictions whatsoever, meaning you can use it on the go and in the home, which is better than you get with most.

Unsurprisingly they also allow P2P filesharing, accept Bitcoin and their client and software boast a range of features not found in many places elsewhere.

CyberGhost’s offering is made all the more appealing by the existence of a no-strings-attached free version that’s almost as good as some of its competitors’ paid plans. With plenty of servers and countries to choose from, as well as a strong commitment to privacy and transparency, CyberGhost makes for an easy recommendation, especially for users wanting to try a VPN for the first time.

At the time of writing, CyberGhost’s service offers access to over 550 servers in 30 countries, including some in Oceania and East Asia. Free users are, however, restricted to 15 countries across Europe and America. Popular countries for streaming and torrenting, such as the USA and Netherlands respectively, are particularly well represented, and most countries have several IPs to choose from even for free users. The client also allows users to choose exactly which country and IP address they wish to connect to.

Simultaneous use on up to five devices at once is allowed through the Premium Plus plan. Although Premium users are limited to one device at a time, swapping is easy and simply logs out any other connections. Free users can use as many different devices and connections as desired, but this is, of course, limited to the free version of the service.

As well as imposing restrictions on torrenting, the free service shows users ads for CyberGhost products upon connection and every 90 minutes thereafter. However, they’re not very intrusive, as they only appear on the CyberGhost client screen. The free service also disconnects users after six hours, but as there’s no restriction on reconnecting immediately this is never anything more than a mild inconvenience. Even the possibility of having to wait in a queue at peak times isn’t too daunting. Although it wasn’t unusual to see queues of over 3000 clients, we never had to wait more than a few minutes to get connected.

LiquidVPN is a small Michigan (United States) VPN provider with some genuinely exciting and unusual products. The real eye-catcher is ‘Modulating IP’ technology, which continually changes your IP address, making it very difficult to track your actions on the internet. This is not, however, the only trick that LiquidVPN has up its sleeve, as its custom VPN client is pretty groovy in its own right, but can also be customized with increased functionality using downloadable scripts. Add to this a no usage logs policy, use of shared IPs, great encryption standards, and a very low starting price, and you might forgive us for getting quite excited (despite the fact that LiquidVPN is a US company). Unfortunately, as you will see, some fundamental problems leave us unable to recommend the service.

LiquidVPN is happy to let you download via P2P, although it does ask clients to use European rather than US servers for this purpose. The ToS prohibits the downloading of copyrighted material and ‘any DMCA notices received from our USA ISP’s that can be traced back to you may be grounds for account termination due to violation of our TOS’.

ibVPN is one of the cheapest of the big name VPN providers, so we were curious to know whether such a low cost service could deliver a high quality experience. We were initially somewhat surprised at how good the service was, both in terms of the features available (pretty much everything plus the kitchen sink on the better packages), and on its speed performance results. Unfortunately, after trying the service out over a longer period of time we had to uninstall it and ask for a refund, thanks to the frequency with which it slowed our whole internet connection down to unusable speeds.
