What Are HTTP and HTTPS Proxies?

The name HTTP proxy refers to a proxy server that uses only the HTTP protocol and its further development known as HTTPS.

The HTTP proxy serves as an intermediary between the browser and the webserver. HTTP-proxies can be used by a browser as well as by some other programs that support the HTTP-protocol, e.g. Scrapebox, Zennoposter, etc.

Types of HTTP Proxies

1) HTTP proxies differ in the degree of anonymity. The following types of HTTP proxies can be distinguished:

HTTP proxies based on anonymity level:

  • Transparent proxies: With transparent proxies, the user usually does not notice that he is using a proxy connection. The proxy connection is only visible to the website operator or service provider. The main advantage of transparent proxies is that they increase the connection speed by caching data.
  • Anonymous proxies: With anonymous proxies your IP address is hidden. In this case, the target website can see that you are using a proxy, but not your actual IP address.
  • Distorting proxies: A proxy server of this type can be identified as a proxy by a target web site, but will communicate an incorrect IP address.
  • Elite Proxies: These are anonymous proxies that delete user data before the proxy attempts to connect to the target website. With these types of proxies, the target website cannot detect that a proxy is being used, nor can it identify the user’s IP address.

All reputable proxy providers that have HTTP proxies offer only elite proxies. The other types of proxies are found in free public proxies, which we explained in the article “What are free or public proxies?”.

2) HTTPS

With HTTPS the data transfer is carried out via an SSL connection – the transferred data is encrypted.

A proxy server whose settings allow connections to port 443 through the CONNECT method is called an HTTPS server.

If such connections are not allowed, you cannot connect to a website that uses the HTTPS protocol.

How secure is a connection through an HTTPS proxy?

When a user using an HTTPS proxy opens a web page with a “lock icon” to the left of the address bar, the entire connection between the user’s browser and the server of the target site is encrypted (SSL encryption):

Browser <- > HTTPS-Proxy <-> Target page

This means that all data entered by the user on the keyboard (logins and passwords, credit card numbers, etc.), images, and videos downloaded, uploaded, or streamed remain absolutely private. This means that they are known only to the user and the owner of the target website.

Can the proxy service “listen” to the traffic?

No, this is technically impossible. The proxy provider can only guess that the user is trying to hack passwords to accounts on any website. This is apparent from the frequency of access to the login page of the target site. This will occur if the user does this at a frequency of one million times per minute using a brute force program.

What ports do HTTP and HTTPS proxies work on?

  • Normal HTTP proxies work on 80, 8080, 3128, 3129 ports
  • HTTPS proxies work on port 443

What are HTTP proxies used for?

  • Cache uploaded files (images, pages) to increase the speed at which web pages are opened
  • restrict access to certain resources (e.g. social networks)
  • To filter data. For example, to display transparent images instead of display banners, which do not “disturb” the design of the website and significantly reduce loading time and traffic.
  • To reduce connection speed
  • To log and control the logins and traffic for each user
