What is a proxy server? What is a proxy server and what is needed? What does it mean to work through a proxy in

Golovna / Optimization of work

The phrase “anonymous proxies” is almost universal for anyone who surfs the Internet. Very few people know what this is for, what it is meant for, how to get rid of it and why it is necessary to burn. If you also consider similar nutrition, then in this article we will help you to understand the types and clearly basic concepts.

Robot principle

Physically, a proxy server represents a separate server and functions as an “intermediary” between computers of users and Internet resources. In most cases, the work process can be described as follows:

The client connects to the proxy and overpowers the request using the method of denying access to the singing resource
The proxy server reads the client's request and redirects him further
After the data packets are removed from view, they are processed and redirected to the client’s IP address

As a result, you can change or receive the identification data of the client’s computer, associated with its IP address.

Anonymous proxy servers are used today even more widely by both primary traders and people who work and earn money on the side. Stinks are allowed:

Bypass restrictions on access to blocked sites and services
and preserve the anonymity of the border, increase the level of security
Increase your speed Internet connection
Access instantly anonymous cloud records from social networks for SMM promotion

Is also known as Gateway (servers) proxy, which is used by Vlasniks and administrators of Internet resources to change and balance the balance on the main servers, protect against DOS and DDOS attacks, capture information about the relevant development and characteristics .

Common proxy servers are divided into three groups:

HTTP – operates using the HTTP protocol, allows you to view web pages, download files from the Internet
SOCKS – work practically with any edge traffic, use vicor for that program
CGI – which can be processed through the browser

HTTP proxies are divided into:

Elite – use the IP and the very fact of using a proxy to ensure maximum anonymity.
Anonymous – they mask the IP, the fact of vikoristan is not wanted
Prozori – stop for or redirect to another server

There are also free and paid proxies. The advantages between them lie in equal anonymity, stability of work, speed of access, reliability and durability, and availability of technical support.

How can I start to get involved?

If you want to connect a proxy server to work on the Internet, then feel free to contact us - we will provide detailed instructions and advise you on everything. Connection and setup won’t take you a lot of time, but it’s simpler than you might think. Just a few words, and you can no longer worry about limiting access and preserving anonymity.

Meals about those How does a proxy server work? And what do you mean, this is often asked about the use of computer devices. This is due to the fact that proxy-server is translated from the English language as an intermediary server. The name makes it clear what the basic principle behind which a proxy server operates is, and it is necessary to understand the specifics of the work, as well as understand whether such an intermediary is needed and how it can be used.

Vikoristan proxy server: reasons

Situations for which it is necessary wiki proxy server, may be different, for example:

1) through the modem, the computer device does not have direct Internet access;

2) for these other reasons, prostitutes cannot use the Internet (for example, they are protected by their superiors);

3) if the webmaster carries out ongoing manipulations with the site optimization method, the optimizer’s IP addresses can ban any other resource, and then deal with that resource and review It’s already impossible.

In all over-insurance situations, a proxy server will come to the rescue, and the customer will also deny access to Merezha and the site that you click. All you need to create for the “green street” on the Internet and for the necessary resource is to install a proxy server on your computer connected to the Internet, or a small and lightweight program, which you can find in Merezha without a person.

Advantages and disadvantages of proxies

Installing a proxy has both advantages and disadvantages. Advantages:

1) the ability to surf the Internet;

2) it will be much easier for hackers to get into your computer;

3) saving money, so there is no need to buy a modem;

4) no need to pay the provider for Internet connection.

The proxy server probably has at least one. The computer on which the proxy server is connected communicates with a third-party computer device in one channel. And since these third-party devices are no longer confidential, the pages on both computers will open up much better.

Types of proxy servers

Before you use a powered proxy server, you need to know that there are many types of programs, including HTTP, HTTPS, FTP and SOKS. Each type of skin works in its own way, always principle of a robotic proxy server HTTP means that when the client is asked (that is, your address, which you need to go to), the proxy goes to that address and remembers it. More precisely, the proxy remembers how to find the DNS server, which assigns the username of the website to the machine name, which is its IP address. With further removal of the sides, this will definitely protect the hour.

In addition, if HTTP is configured properly, you can save images of these and other sites and other information. When you further navigate to a specific page, the server looks at its content and detects changes instead, upvotes them, and the main content is upvoted from the server cache.

The HTTPS server follows a similar principle, with one caveat: all traffic flowing from the client to the web resource is encrypted. If your computer has both a proxy and a spyware program on it, it can cause unreadable symbols.

SOCKS proxy server is working behind this very principle, like HTTPS. Visibility is comparable to encryption: SOCKS encryption is much stronger.

Anonymity and insight

All proxy servers can be anonymous, secret or transparent. Until then, there are proxies that do not change the client’s data, transmitting them as if they were stolen. In other words, IP addresses will not be changed, and therefore you can determine who is going to the services of a particular station.

Anonymous servers are expected to change information about others in this way. This allows the client to access various resources anonymously, incognito. In the IP address parameters, the address of the proxy server itself is displayed. Such proxies themselves will be installed by web masters and most traders.

But such kindness is one positive side of the coin. It’s different, less positive. Often the computer wants to use this method of security for a new maximum level of protection. I shut the bilshi of the proxi-server-a-seniorly tested stupid zhista vid invasion Zzovni, I.

Be careful!

At the same time, there is a trace of memory that proxy server There is no doubt that the presence on the computer will still not provide a hundred-hundred-hundredth protection to the device from the penetration of viruses. Remember that if you have your IP address, you can easily get a virus through your browser if you download suspicious software. The first “symptom” of the fact that your computer is no longer “one” is that if you see such a file, you cannot delete any file. So be careful!

This proxy server will bring you a lot of information. Golovne - vikorystuvati yogo pozmolivosti correctly and lose respect.

The word “proxy” has come to almost every one of us, but not everyone knows what its meaning is.

Proxy is an intermediate link between the client’s computer and the Internet server system. Also, since access to the WWW is not done directly, but through a proxy, then you will have to immediately go to the middleman, who will obtain it and send it to the required address under your name.

What kind of proxy can be used to connect to the Internet through such a server? The main goals of this blog:

Caching files and storing them on a proxy server to reduce the load on the Internet channel and to reduce client access to the required information.

Condensed information after being retrieved from the Internet and transferred to a compact device to save traffic.

Protect your local computer from external threats.

The ability to connect a number of computers to the Internet, although they may only have one IP address.

The proxy server can be configured in such a way that external computers cannot communicate with local machines, but only an intermediary.

With the help of a proxy, the system administrator can block access to low websites.

Anonymity of access. You won't be able to secure your tracks with the increased cost of WWW using just one server. For whom do we need a little “proxy”? But finding the required proxies and making such connections with the correct sequence is far from easy.

What is a proxy for a cross-border merchant? It is advisable to visit websites that have been blocked.

Proxy and setup for robots? There are a lot of options, among them you can find a free or paid proxy server. The choice depends on the technology of connecting your computer to the Internet.

To install it manually, you need to know the lists of proxy servers. For whom should I ask for a job, for example: catless and otherwise. From the results, select the site you are interested in and open. The registered list will have a lot of “dead” proxies, so they need to be checked for efficiency, for which a special function has been transferred to the sites. After verification, a table with the results will be generated. You need to take a few different options and save the addresses on your computer.

I forgot to install them and configure them in my browser. These activities are of concern to different observers. Detailed instructions for future installation can be found in the section. After setup, you need to check the proxy server again for functionality. If you need to log in to a proxy, you will need to check the box

It is important to note that working with paid servers is more reliable, they are reliable and less likely to malfunction, and more fine-tuning is possible on them. There are no costless proxies, their advantage lies in the fact that they are anonymous, disguised as paid ones, and information about the client is saved by the authority. You can use several servers without fees, and if one of them fails, you can simply switch to another one.

Now you know what a proxy server is and why you can use it.

Proxy is an intermediary link between the computer, both the subscriber and the system of Internet servers. If you don’t go into terminology, there is an intermediary computer for connecting the user to the Internet. Its main instructions are for the broadcast of all requests of the correspondent until they are removed and removed. The report about those proxies that operate the server and how they exploit it will be discussed below.

How does proxy communication work?

Each computer from which access to the measure is performed is assigned a unique IP address. Your job is the identification of the Internet account manager. IP addresses carry information about the country and region, the number of the Internet provider and personal computer in that area. Proxy servers are also assigned unique IP addresses. After connecting to the proxy, the transmission of requests will show that they are coming from the intermediary server, and the subscriber himself can save his incognito (when working with free servers, on paid ones, information about the client The information is saved).

To connect to a proxy, you need to configure the settings in your browser, which will be used to enable the proxy requests. All current connections will be connected to the IP address of the proxy server. If you need to access any web resource, the local computer will openly connect to the proxy and ask. After checking the correctness of the request, you will be connected to the resource. Then the received confirmation will be transferred to the subscriber’s computer.

Good news and who needs a proxy

Today, proxy servers are used mainly to obtain a valid IP address. There could be several reasons for this. The most popular is the need to view the site, access to any blocking for your IP, and the need for anonymous mail sending. More drives if you need a proxy:

protection of the network or local computer from various types of network attacks and the need to protect confidential information;
limiting the access of clients to various types of web resources. It is practiced by companies to prevent the irrational wastage of working hours by employees;
You must connect a number of computers to the Internet using the same IP address. The adjustments can be made in such a way that information about local machines will be received from external machines, which can eliminate the need for an intermediary;
the need to save additional traffic - removed from Merezha, the information will be transferred to a compact form;
the need to reduce demand on the Internet channel and provide clients with quick access to information. For such situations, files are cached and stored away on the proxy server.

Proxies can be found on many websites, but they are laid out without cost. Another option is to download a special software that allows you to use the edge filter and test the speed and performance of the proxy server. Another way is to buy a “high-quality” server on special sites.

Advantages

They gained the greatest popularity in the corporate segment - through them they themselves gain access to online settings from local legal boundaries. I was blessed with the following achievements:

Proxy servers are supported by the absolute majority of home web browsers;
There is additional access control, manual traffic flow, and filtering (in case of integration with antiviruses);
the ability to work with minimal rights on any operating system;
The availability of access to the Internet behind other protocols significantly promotes the security of the exchange of corporate information.

Regardless of the popularity of certain bridging protocols, proxy servers will continue to be used in enterprises. It doesn’t matter how many inexpensive hardware routers with NAT function appear. This is mainly due to the fact that most routers are not able to provide sufficient control over Internet access and content filtering.

Prozory- A linking scheme that redirects the router part of the traffic (or all) to the proxy server. The advantage of this type of connection is the ability of the client to use all the advantages of the proxy server without any adjustments. This is not long, which saves the choice of choice.

Zvorotny- a proxy server that is used to balance the balance between a number of web servers. In addition, my duty is to promote my safety. At times, the return proxy server is assigned the role of a border screen for the application layer. When the server is up, requests from servers are relayed from the outer edge to one or more servers located at the outer edge.

In addition, proxies are divided into insightful and gateway types, they can be classified as follows:

HTTP- the most popular and universal type of proxy that can be used for a wide range of tasks. Most of the daily workload encourages work with it;
Socks- a type of proxy, with which the program is far from being useful. It requires installing additional software in browsers, so you don’t support Socks for cleaning;
CGI- Interaction with them can only be done through the browser, otherwise CGI support does not work. Another name for this type of proxy is an anonymizer;
FTP- a type of proxy that is often used in corporate networks as one of the warehouses of a single system for protection against external threats.

The rest of the time we have been eating more often, connected with the fact that such a proxy server is how to safely increase the price of the Internet by taking your IP and how to waste it on sites blocked on robots (after all, they stink, crooks, because they want to fool one of the administrators for help with others admin :)).

To write this article, we took a sample of an IPv4 proxy from the service we verified in order to demonstrate all the settings in the form of detailed instructions.

Well, I decided to write an article, as far as possible, as evidenced by this diet.

What is a proxy?

All the terminology (but not the whole article) is written based on Wikipedia or simply copied from the material that it confirms there. This was done in order to save time, and also from the point of view of completeness, because I don’t want to paraphrase those that have already been miraculously written and may still avoid what I want to write.

A proxy server (from the English proxy – “representative”) is a service in computer networks that allows clients to make indirect requests to other third-party services.

Initially, the client connects to such a server and requests from it any resource that is distributed on another server on the Internet. Then the server either connects to the specified server and takes the resource from it, or retrieves the resource from the free cache (then from the resource already saved to itself) (which, of course, has the same cache).

Is the proxy server getting stuck?

Most often it is used for the following purposes:

Secured access from local computers to the Internet;
Keshuvannya tributes: since the most external resources are often accessed, it is possible to trim a copy of them on the server and view it behind the request, reducing the demand on the channel from the external network and quickly removing the requested information from the client tsії;
Data compression: the server collects information from the Internet and transmits the information to the end user in a simple manner. Such proxy servers are used mainly to save external traffic;
Local measure protection VID Callonish access: the way, the server is able to catch the server so, the local compoers will be at a glance to the calls of the nyo, and the calls are not to the local mugs (the surroundings of the tilki tilki);
Access restrictions from a local network to an external one: for example, you can block access to other websites (which, of course, is our responsibility, evil admins:)), limit the Internet to some local accounts, set quotas for traffic or access Nya, filter ads and viruses ;
Anonymization of access to other resources. The proxy server can receive information about the device or customer. In this case, the target server only needs to collect information about the server, such as the IP address, so that it is not possible to determine the correct destination. It's the same proxy servers that support, which transmit false information about the customer service provider to the target server;
This allows you to protect the client computer from various edge attacks.

Proxy servers are divided into open and closed. Unlock these things that you can deny access to, regardless of your Internet connection. Close it, of course, anyway.

In this article, we need to open the proxies, and let’s take a closer look at them.

Open proxy - anonymous and primary

An open proxy server is a server that allows any network node (a client, or, say, you) to communicate through itself to other network nodes (on any site or anywhere else).

For the record: although I seem to be measuring, I’m not only focusing on the local area, but also on the Internet.

Open proxies are also divided into two subtypes:
Anonymous and anonymous.

Anonymous - these are the ones that capture the real IP addresses of clients and thereby give you the ability to anonymously surf Internet services.
First and foremost, they do not receive anything from anyone and see your real IP and all other types of data.

KRIM Anonimnosti, in the time in the Tsіni trafic in Riznikh Merekh, Vidkritiy Proksi-server, Scho is known in their own Merezhi, can vicoristovati for the Otorimann Bilsh of the dear trafi of the Merezhi Merezhi. So, for example, many Russian clients who have been blocked from accessing foreign sites on their computers can still deny such access through a hidden proxy server.

Speed of robot proxies

Because of the speed of the work, there is significantly less traffic, and even, in essence, the traffic appears to be going through the additional server, but the delays are much greater, even though the traffic is not in the middle. These proxies are used, as a rule, for a specific operation, if it is not the speed that is important, but the reach (access to a particular resource).

As you understand, there is a big problem with this proxy, since such anonymity can easily violate the law and the integrity of Merezha’s services, and therefore, the sites of certain Internet services block access to your resources from protected proxy servers (for example, - this Yandex mail service).

Garazd, the theory has been laid out. Let's get to practice.

How to process through a proxy server?

There are ways to work through a proxy: this is the way to set up the network (globally), or the way to set up the programs (locally, then, let’s say only for).

In this article we will look at the global option for changing the settings, and within the framework of the decision, I will tell you how, for example, based on a plugin for or programs for the entire system.

I would like to immediately say that the option of global change, adjustment, frankly speaking, is not entirely global. On the other hand, in Windows there is no concept of a global proxy as such, but it is only possible to set up a “smart global option”, so that for such programs you can set up a proxy from Internet Explorer. For all others, you will have to order proxies from the authorities (programs) configured.

To begin with, we need to know the secret proxy server. You can forgive this by asking: " list of anonymous proxies"either" list of protected anonymous proxies There are plenty of sites with lists of proxy servers, although not all of them work, so you will have to struggle with the selection.

What is important to know when choosing proxies

Marvel:

It is important that you do not hesitate;
It is important to understand that the higher the value of ping, as indicated here, the greater the number of requests to be made to the proxy and back and, as a result, the greater the demand for sites;
It is important to understand that the address 127.0.0.1:80 means that 127.0.0.1 is the address of the proxy server, and 80 is the port;
The country is indicated opposite the proxy server (as it is indicated again), which means that the server has been rebuilt. practical for everyone You will be of this end because your IP will be the IP of the proxy. Well, of course, the distance of the edge from yours affects the ping to the server;
Not all of them are bad, because they all have different settings and may not allow you access to all resources (for example, the US server may only allow you to access com-sites, etc., etc.), and so on. resources may not allow you access if they suspect you are accessing them through a hidden proxy server.

Ping to the proxy server and the result of the address you have found can be verified in the following steps: Start - Vikonati - cmd - Ok. The window (console) that appears requires you to enter " ping the server address" and press the enter button. Example:
ping 127.0.0.1:80
If the server is available, then 4 packets (maybe fewer) will pass through, which will show the power of the ping, and the presence of the ping confirms the presence of something at the specified IP.
If it is inaccessible, then nothing will pass and nowhere.

How to allow traffic through a proxy

Having known the working server, we need to tell the computer that we want to send traffic through it. You can earn money in two ways (the third way is not quite the same), which follows the principle of validity:

Global method
You can send all computer traffic through a proxy, then. install global adjustments. As a result, ALL programs that otherwise operate on the Internet (browser, ICQ, FTP, etc.) will be accessed through him.

To start, go to: Start - Settings - Control panel - Powerful look around- Connection - Adjustment of boundaries. There we check the box “Victorize proxy server”, write down the address and port, and stamp OK.

It is important to carefully read the checkbox, because it says there that VPN connections will not be blocked for remote connections. Tobto. Unfortunately, if you have one of these types of connections (for example, a corbina), you won’t see anything.
Then show the trace to local services. Depending on the operating system you are running on, issue the command:

For Windows XP:

For older Windows:

netsh winhttp import proxy source=ie

The pouch will look like this:

Local method
You can also enter a proxy in the settings of the skin program. Apparently, the skin program in which you will tell it to work through this very protocol, and decide to access the Internet as soon as possible, without any delay. It’s good that you don’t need any anonymity anywhere except on ICQ web pages, then, of course, everything can be adjusted.

Well, as an option, you can configure the work of different programs through different proxies. Where should I set it up? The skin program has its own place, but it’s not difficult to know the cause. In Mozilla FireFox, the settings are delayed behind the address "Tools - Settings - Dodatkovo - Merezha - Connection - Setup"

Worldwide or expanded
If you need to go to a page that is blocked for some reason or you don’t want to connect to that page with your IP, or just joke around and set up proxies, then you can quickly access such a site or extensions (on the desktop);

You can use Vikorist VPN. The series of articles on the topic is still alive.

There are other ways, but I don’t want to blindside them yet. Moreover, the software method will be more practical and manual. Please make sure to check out the other parts of the article, rather than dwell on the first one.

Pislyamova

To be honest, it’s hard for me to spot people who would be willing to pay in order to get their IP and anonymously increase the price of the Internet.

This method of self-defense often smells of paranoia or unkind plans, but still... Still, I would like to know about this because local networks are most often organized through them (offices, offices, homes, etc.), and they sparked little what, whenever and wherever you can benefit.

Well, well, it’s a bit awkward, since you’ve been banned by IP here and you need to quickly get to the site.. That’s it:)

As always, for food, thoughts, additions and so on, we kindly ask you to comment before this article.
