Today, many people use proxy servers to make sure they have a safe, secure connection while surfing the Internet. For some, it's required since there aren't all websites accessible via private IP addresses. However, some people find it simple to choose a method that could allow you to be sure that none of your private information can be passed out to third hands.

There are numerous types of proxies in the market today but how do a newbie to the sphere pick the right one? HTTP proxy or HTTPS proxy anonymous proxies or transparent ones?

Luckily for you the entire information you need is laid out in the guide below, so that you are able to select a server to use based on your needs only!

HTTP Proxy or HTTPS Proxy: Which Do You Choose?

The two most significant differences between the different kinds of proxies are HTTP and HTTP proxies, which is why it is essential for those who are not experts on the subject to understand the two types of proxies first.

In the next paragraphs, we'll provide you with an explanation of how these two types that are proxy servers vary from each others, to help you gain a an understanding of how each proxy server functions.

HTTP Proxy

So what is the proxy HTTP?

HTTP is interpreted for HyperText Transfer Protocol, and it acts as an intermediary between you, the user, and the website that you want to access.

Here is what happens to your requests to visit a specific web site during the time an HTTP proxy server is on:

  1. Once the user has sent the request to a website they want to visit (which is usually done by clicking on its link) however, the web request is not sent directly to servers of the website. Instead, it passes through the HTTP proxy first;

  2. After the request is received when it is received by the HTTP proxy, it is examined, and the information it gathered is then used to create another request. This one is then sent to the web server. It's done in order to hide your IP address to ensure that the web server isn't able access your private details;

  3. Once your HTTP proxy server sends your HTTP inquiry to the web server, it will be processed by an server from the intended destination, and the response to the client will be created;

  4. After that you will receive an answer of the web server which will either be allowed to connect to the target site or not allowing you access to the website at all.

When all of these processes are documented they could appear to suggest there's plenty to be done by both the client as well as the HTTP proxy servers for the requests to be sent. However, when a decent good proxy server, like ProxyWOW is used All of these actions take milliseconds or less to perform.


After you have a better understanding of the way HTTP proxy work, you might ask yourself why there be a need for another type of proxy server?

  • HTML0 Well it's true that the HTTP protocol that is used to get an answer from the destination site may not be enough often, and that's why it is why the HTTPS proxy server was created for the purpose of repairing its shortcomings.

  • request for HTTP traffic is sent directly to a remote server of the website in the format of plain text, which implies that security is not the best and a lot of sensitive information such as your passwords and credit card number could be easily observed by anyone, and we certainly do not want that to be the case with an intermediary.

  • HTTPS proxy is an upgraded HTTPS protocol that encrypts information using CONNECT to ensure that no one except for distant servers on HTTPS site can access anything in the message that the client submits.

  • Two types of protocols that could be used for the HTTPS proxy to establish what is known as a TCP connection between the servers and the clients on the network. These protocols are called Secure Sockets Layer (or SSL) and Transport Layer Security (TLS).

URL and HTTPS Proxies Benefits as well as Cons

  • Collecting data;

A client for HTTPS this list of actions you could perform through HTTPS connections:

  • Everything that was already identified above;

  • It is possible to purchase any product online by filling out your banking information;

  • The process of logging into your social media accounts that are requiring authorization.

The cons of being an HTTP client As you might know, are related the fact that security may not be the best as you can't submit any personal details when applying the HTTP proxy. As for the downsides of creating an HTTPS request, our personal experience tells us that the only downside is the fact that it might be more costly to purchase web proxy. web proxy to make HTTPS requests.
