How it works and types of proxy connections


Different methods of data exchange are used to connect the user to the network. One of these types is a proxy, in which subscribers are connected to server systems using remote intermediary computers. The functions of this link are to process and encrypt user requests and responses from addressees.

How proxies work

When accessing the Internet, subscribers receive certain IP addresses. This is a set of numbers compiled according to special algorithms, designed to identify users. They contain codes of states, regions, data of providers, personal computers from which the request was made. The same unique addresses are assigned to intermediary servers. The signal from the subscribers is sent to the remote platform, processed there, and as a result, the addressee receives a signal from a different IP. In this way, the user retains his anonymity, it is more difficult to track him on the network.

To use a proxy connection, you must set the appropriate settings in the browser you are using. All subsequent requests from a PC or local network will first be directed to the remote server. After processing, checking the correctness of the data, the subscriber connects to the required resource with a new IP address.

Reasons for using a proxy

The main purpose and function of a proxy is to ensure anonymity on the network. This method of connection is often used to bypass IP blocking of individual states, regions, and specific users. In addition, there are a number of other important reasons for using an intermediary link when accessing the Internet:

  1. Sending anonymous messages, emails.
  2. Ensuring confidentiality of information.
  3. Increased connection security, additional protection of local PC databases from hacking, hacker attacks.
  4. Many companies and providers use proxies to restrict user access to certain unsafe resources, sites with prohibited content.
  5. The ability to connect to the Internet with one IP local area networks from multiple computers.
  6. Saving traffic. After processing the data by the proxy server, the subscriber receives information from the resource in a compact volume.
  7. Reducing the load on the connection channel, the destination resource. Caching files with subsequent storage on proxy servers increases the efficiency of data access.

Many platforms, and in particular Proxy-Seller, provide free services for connecting a user to the network through a proxy. Paid servers provide more reliable, faster and more secure connections. You can also install special software that will allow you to test the speed, monitor traffic, apply various filters, for example, select a region code.

Proxy connection types

Proxies can be conventionally divided into groups of transparent and reverse communication schemes. In the first case, traffic is fully or partially redirected to the remote computer without any additional configuration. The reverse scheme uses connections through one powerful or multiple servers. In this case, both the subscriber’s requests and the recipient’s response signal are processed. This method provides more reliable protection, data anonymity.

There is also the following classification of proxies:

  1. The most common, universal connection protocol. Supported by almost all browsers, websites and software.
  2. Anonymizer, which can only be used through browsers, there is no special software for it.
  3. Differs in increased security of connection and data transmission, is often used by corporate networks to protect against external attacks.
  4. Requires the installation of special software on the computer and in the browser.

In general, a proxy is a reliable way to ensure anonymity on the network. All browsers support connection via remote servers; using this scheme increases the protection of databases from hacking.
