There are a number of proxies that exist on this planet earth and not just one. Believe your eyes, you read that right! Many people when talking about proxy are still oblivious to the fact that there are a number of proxies that exist in the market. The term proxy is a huge topic to talk aboutit is not just limited to the use of it, but unfortunately still in this century, even the proxy users haven’t been nice enough to learn completely about how proxies work. No justice, right? When they talk about a proxy, they think of it as a single entity that is same everywhere; just like water (but even water has types!) So there isn’t just one regular ever day proxy connection, other types exist too and it would be an elementary mistake to think that all of them have the same function or they work in the same manner.
In this era of modernization where even the new release of anything gets old with just a blink of an eye, here no expert will take you seriously with the old information about the proxies that you hold within! We have to proxy-literate ourselves very quickly in order to catch up with the world and so we can use them beneficially for our needs.
Don’t you worry we are here to make your learning pathway as beautiful as you might feel while walking on crunchy leaves through the autumnal trees! So in this blog, we will talk about two of the famed types of proxies that are selling like lava cakes in the market today; the reverse proxies and the backconnect proxies. We will learn what these types of proxies are, and how they differ from each other. We will also tell you about how they actually work. But before we jump to our main topic it is very necessary to talk or to learn about a normal proxy and how these differ from others. Now tighten your seat belts we are about to take off to learn a lot of new stuff!
Normal proxies are the simplest form of proxies. These are also called by many other names out of which the chief one being ‘The Parent Proxy.’ Quite obviously these are called Parent proxy because all the other proxies are just the byproduct of these parent proxies.
The normal proxies are simple in their factions and operations, but they can be easily modified and manipulated to different variations. And the two proxy types that we are talking about today are also derived from the normal proxies.
What is a (Normal) Proxy?
A normal proxy is a third-party computer/server that is present in between you and your target site. When you enter a web address, you are basically sending a request to the target site from your browser. The request that you send goes from your router and modem. This goes out to a number of places that includes an ISP (Internet service provider) server, to an internet backbone (it is one of the main data routes between large connected computer networks and principal router on the internet), a street-level router then to a neighborhood router after travelling through such a long path it finally reaches the destination which you were trying toget to. Website servers are secured with direct connections to internet backbones, which happen quite frequently. When this comes off, then the street or neighborhood routers don’t cross your pathway thus subtracting the extra time that they may add.
Sometimes, proxies can make your connections extremely slow. Proxy is an additional step. Being an extra step then how fast of a proxy you use, what protocol it uses or how powerful of a machine you are using doesn’t affect the latency caused by it. This is one major snag with most of the proxies.
Any computer can be turned into a proxy server but with the right arrangement.It does not necessarily have to be a high technological hardware but it further delays all the process going on in the background. Topographically, a proxy serves lies in the middle, usually in a foreign country. So, a proxy connection might have to jump over an ocean or has a wireless conveyance along the pathway somewhere.
The direct connection goes from your computer, through routers, into the web host server where the website exists. After getting the information you need, it returns back to you through the pathway it went from earlier. Variation in the information is uncountable; it ranges from the simpler information of page loading to a more complex one of downloading an application.
The information or request that goes from your computer when reaches a proxy, it removes any important personal data, it may hide your Internet protocol (IP) address that can make you discoverable and fills it with a different information or sometimes doesn’t. There are different levels on which the information gets altered; 1) anonymous 2) transparent 3) distorting.
- 1. Removal of all the special data that may lead back to you. Hence making you fully secure from the internet pirates that are sitting on the opposite side of your screens.
- 2. In this, your information doesn’t get altered at all. In fact, these are used to forward the data rather than connection information.
- 3. It changes and also deletes some data. The web server does get some of your information but it might not be completely correct.
This step does delay the process but it is very important for maintaining privacy.
There are some networks which are semi-anonymous. Your connections pass through these networks before reaching the target site. One of the examples of this semi-anonymous network of randomized proxies is Tor also known as Onion Router. There are some privacy concerns with Tor but these proxy networks are way better than the transparent proxies which do not hide the information. In an onion routing network, messages are covered in layers of encryption and the data of the encrypted message is forwarded through a series of network nodes called onion routers. This is how anonymous communication over a computer network occurs. Tor network is quite similar to backconnect proxies.
Standard proxy servers may have restricted access for those who pay to get the connection (a private network), or it can also be an open network to which anyone can have access to (a public network), so this way proxy servers can be configured in a number of ways. These can be fast or slow, can go unaltered or can be interrupted by advertisements. They can connect using HTTP or SOCKS. These can be located in many different countries (USA, Britain, German etc.)
Proxies are definitely good in keeping your identity hidden but not to a fuller extent. They keep anonymity and secure you to only a minimum level. A single proxy cannot very well maintain the privacy; you might need to use multiple proxies. But then again the use of proxies can only protect you from your mischievous neighbor or enemy or the online thieves but it cannot protect you from Federal Bureau of Investigation (FBI) or another department like these.
If you are worried about privacy then proxies like Backconnect proxies or Tor are the ones that you can always count on, these are somewhat more secure than the others. But these are not for regular browsing, these are used more for something like bulk data scraping.
As explained earlier, Backconnect is quite the same as Tor. Backconnect proxy works the same as the normal proxy does. The difference is in the proxy server or the network. The main advantage of Backconnect proxy is that it is not a single proxy server machine. It uses different machines and different configurations.
There is a pool of proxies out of which different addresses are used but for only a short period of time. You will be using one proxy and in the background, you will get switched to a different one within say a span of 10 minutes or even less. And from second to third and so on. Even if you are using a small list of proxies you continuously get switched to different proxies. If you search something on any search engine you’ll be using one proxy, when you are taken to the page of search results without knowing you will be using a different one. This is how quickly you get switched between a number of proxies.Every time you send out a connection, the proxy connection changes. Basically, it changes with every move that you make.
These proxies also help in concealing your current location. Rather than showing the correct area from where you are browsing it covers it up and shows it as a different geographical region.
If you are trying to rake data from sites like mother Google, then on seeing too many connections coming from one single server, Google is most likely to put a captcha (which is a test to tell humans and computers apart- Completely Automated Public Turning test to tell Computers and Human Apart) on any action you do. Even on passing the test, many connections at a single time can get your rate limited for minutes at a time. Here backconnect proxy pool jumps in like a superhero to save your life. It allows you to make more requests per minute which no other connection does.
Every connection you send will go out with a different IP address, which Google can never group up to make a link leading back to you. This way no site can impose a rate limit; even if they do it will only be on one IP which will have an effect on nothing.
Of course, nothing on this planet is perfect! Everything has its own flaws and so does backconnect proxies. These help you to protect your data and also allow you to send various connections at a single time but all of this doesn’t come off easily. These lists are quite expensive to have access to. And also these connections are very unpredictable, some of them work too fast while others may be very slow and some of them can also get banned from the site you are trying to get to!
These proxies, as the name says, really do work in a reverse manner! They do not work for you or in other ways they don’t keep your anonymity. Rather than working for you they work for the website. These are used by websites to keep themselves protected from the different types of connections or use it as a firewall, additional security measure or filters.
Web servers rather than getting directly connected to the internet instead they get connected to reverse proxy. These proxies act as a web server. When you are browsing you get connected to the website and only see the proxy but you do not get to see the server behind it. The proxy here acts as a web server and hides the original server IP.
Reverse proxies can be used for multiple purposes by the companies or websites. These can be used for split testing by routing traffic to divide between two different servers. The websites can use these proxies to hide details of their internal server structure; these serve them very well against all the hackers. The reverse proxies might also have hardware which speeds up the verification of SSL certificates. These proxies can also control data compression for the web servers which helps in providing faster connections. It acts as a load balancer too, by doing so it reduces the load on all the internal servers. The website may also use them as they can be used as cache. It does web acceleration (provides dynamic data to various clients at once, if the request is same.)
All of its benefits are for the companies or websites using it. These are not used in normal, everyday browsing and don’t serve to protect an individual’s data like backconnect proxies do. In simpler words for casual browsing one uses backconnect proxies while companies use reverse proxies to keep their data protected.
