In the present, a large number of users use proxy servers to create a safe and protected connection when surfing the Internet. For some, it is essential since many websites are available from private IP addresses. But for others, it is only a matter of choice to be a way to ensure that no personal information is passed an unauthorised third party.

There are numerous types of proxies that are available today, but how can a newbie to the sphere choose one? http proxy or HTTPS proxy anonyme proxies or transparent ones?

Luckily for you all of this information is made clear in the information below so that you can pick a proxy server based exclusively on your requirements!

HTTP proxy or HTTPS proxy: Which to Pick?

The two major distinctions between various types of proxy sites are HTTP as well as HTTP proxies. This is why it's vital for anyone new to the subject to get familiar with them first.

In the following paragraphs, we are going be describing to you how these two types of proxy server differ one of them, so that you are able to get an understanding of the basic principles behind the workings of any proxy server.

HTTP Proxy

What exactly is an proxy on HTTP?

HTTP can be deciphered to be HyperText Transfer Protocol, and it acts as an intermediary between you, the user and the site is accessible to you.

This is what happens when you request to connect to a specific site whenever your HTTP proxy server has been activated:

  1. After the user has sent the request to the web page they want to access (which usually happens simply by clicking the link) The web request doesn't go directly to the server for the website. Instead, it passes through an HTTP proxy first.

  2. Once the request has been accepted in the HTTP proxy, it's scrutinized, and data from it can be used to generate a second request, the one that is sent to the web server. This is done to make it easier to disguise your IP address, so the web server cannot access your private information;

  3. After the HTTP proxy server sends your HTTP message to the web server, it is processed by this server in the desired site so that a response to the user will be made;

  4. Then you'll just get the response via the web server which will either be providing access to the web page you are trying to access, or not allowing you to access it.

When these procedures are listed in a document it may appear as if there is a lot to be done by the client as well as the HTTP proxy servers for requests to be made. If a proxy server with high-quality, such as ProxyWOW is used each of these tasks take milliseconds or less to perform.

  • Traffic requests from HTTP are provided at the request of the remote server of the website in a form of plain text. This implies that security is not the best because a great deal of personal data such as passwords or credit card numbers could be easily seen by anyone, and we do not want that to be the case with a proxy.

  • HTTPS proxy employs an enhanced HTTPS protocol that encrypted the information using the CONNECT method so that nobody other than distant servers on HTTPS website is able to view anything in the message sent by the client.

  • It is possible to use two types of protocols that can be utilized in An HTTPS proxy to create what is known as a TCP connection between clients and servers in the network. Both are named Secure Sockets Layer (or SSL) and Transport Layer Security (TLS).
