Nowadays, a majority of people use proxy servers in order to create a secure and secured connection while browsing the Internet.

There are lots of proxy services available but how do an unexperienced user choose the best one? Is it HTTP proxy anonymous proxy or transparent?

Fortunately for you, all this information has been described in the post below, so that you are able to choose a proxy server based the requirements you have!

HTTP Proxy or HTTPS Proxy: What to choose?

The two major differences among the various types of proxy are HTTP and HTTP proxies. This is why it is essential for those who are not experts on the subject to get familiar with them before beginning.

HTML0 In the following paragraphs, we'll go over how these two types or proxy servers differentiate from each other so that you get a basic understanding of how a proxy works.

HTTP Proxy

So WHAT IS the HTTP proxy?

HTTP can be identified to be HyperText Transfer Protocol, and it acts as an intermediary between you, the client and the site you want to access.

HTML0This is the process that occurs when you try to access a particular site when it is accessed via an HTTP proxy server is on:

1. When the user makes the request to the website that would like to access (which usually happens by simply clicking on the link) and the web request doesn't connect directly to the server hosting the website. Instead, it is sent to an HTTP proxy first.

2. If the request gets accepted when it is received by the HTTP proxy, it's analyzed, and then the information obtained from it is used to create a new request, which is then sent to the web server. This process is carried out in order for you to mask your IP address so that the web server is not able to access your private information.

3. When the HTTP proxy server forwards your HTTP message to the web server, it will be processed by this server in the desired destination to ensure that the response to the user will be formed;

4. Then you'll just get the answer via the web server. This is either allowed to connect to the destination site, or denying you to access it.

When all the actions are documented, it might look like there's a lot that needs to be performed by the client and HTTP proxy servers to allow the requests to be sent. However, if a top-quality proxy service like ProxyWOW is used the entire process will take milliseconds or less to perform.

• Well, the HTTP protocol that's used to obtain an answer from the website isn't always the answer some times. That's why that the HTTPS proxy server was designed to fix its weaknesses.

• Requests for HTTP traffic delivered to the remote server of the site in the format of plain text, which means the security of the site isn't at its best because a great deal of sensitive information such as passwords and credit card numbers can be easily observed by anyone and we do not want that to be the case with a proxy.

• HTTPS proxy makes use of an enhanced HTTPS protocol that encodes the information using CONNECT to ensure that nobody other than servers that are remote to the HTTPS website will be able to read what information is contained in the request the client makes.

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

Web and HTTPS Proxies Pros and Cons

A.K.A. HTTP client, it may utilize an HTTP proxy provider to perform the following tasks:

• Collecting data;
