Guys, today I'm going to give you a popularization of the topic of http tunneling proxy. Do you know what is http tunnel proxy? It is a magical "secret channel" in the Internet world, so that we can enjoy the fun of the network world more securely and unimpeded.

First, what is the http tunneling proxy

I believe that a part of the partners of the http tunnel proxy is not quite understand, do not worry, I will give you a detailed explanation. Simply put, http tunnel proxy is a proxy service for data transmission through the http protocol. This proxy service can build a "channel" between the client and the server, so that data transmission through this channel. In this way, it can effectively break through the network restrictions, hide the real IP address, and protect the user's private information.

Second, the common type of http tunneling agent

1. Forward http tunneling proxy

Positive http tunnel proxy is a way to initiate a request from the intranet and forward it to the extranet through a proxy server. A common application scenario is intranet penetration, so that computers on the intranet can directly access the extranet to achieve resource sharing. For example, we use a variety of remote desktop tools (such as TeamViewer, RDM, etc.), they are the use of forward http tunneling proxy to achieve remote control, remote access.

2. Reverse http tunnel proxy

The reverse http tunnel proxy is a way to initiate requests from the outside world and forward them to the inside world through a proxy server. This type of proxy is usually used to protect the security of the intranet server and forward external requests to the intranet server. For example, in an enterprise, in order to strengthen the access control of the intranet server, you can use the reverse http tunnel proxy to realize the restriction of the access to the extranet and protect the intranet security.

Third, the realization of the http tunnel proxy commonly used tools

1. Ngrok

Ngrok is a fairly popular free http tunneling proxy tool, which has the advantage of being easy to use and powerful. With Ngrok you can quickly create a secure http tunnel that exposes an intranet server under the extranet and provides access to the outside.

2. Frp

Frp is an open source reverse http tunneling proxy tool for intranet penetration. It supports TCP, UDP, HTTP and other protocols forwarding , through the configuration of a simple INI file , you can realize the purpose of the extranet to access the intranet server .

Fourth, the use of http tunneling proxy considerations

1. Reasonable choice of proxy server

When choosing a http tunnel proxy, you must choose a reliable proxy server. Because the proxy server will take on the task of forwarding data, if you choose a proxy server that is unstable and slow, it will easily lead to data loss, connection timeout and other problems.

2. Pay attention to network security

When using http tunneling proxy, you must pay attention to network security issues. Especially when using the network in public places, avoid using the http tunneling proxy for the transmission of sensitive information, so as to avoid eavesdropping and attacks by lawless elements.

V. Summary

Through the explanation of this article, I believe we have a deeper understanding of http tunnel proxy. http tunnel proxy can provide us with a safe and smooth network environment, so that we can freely access the Internet, to achieve resource sharing. At the same time, the use of http tunneling proxy should also pay attention to security issues, choose the right proxy server to avoid network attacks. I hope that we can enjoy the fun of the network at the same time, but also always be vigilant to protect their own and those around them network security.

Finally, the world is so big, let's explore the wider web world with the http tunneling agent as our guide!
