Problems solved by technology

[0007] The present invention is proposed for the existing problem that a large number of IP addresses are needed when data packets are forwarded by proxy, resulting in the waste of IP resources. For this reason, the main purpose of the present invention is to provide a HTTPS proxy forwarding method based on Transmission Control Protocol and device to solve the above problems

Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] figure 2 It is a flowchart of the first embodiment of the transmission control protocol-based HTTPS proxy forwarding method according to the present invention. like figure 2 As shown, the method includes the following steps:

[0030] In step S102, the HTTPS proxy server without a certificate establishes a transmission control protocol connection with the client.

[0031] The Transmission Control Protocol (TCP for short) is a connection-oriented (connection-oriented), reliable, byte stream-based transport layer (Transport layer) communication protocol. In the simplified OSI model of computer networks, it completes the functions specified by the fourth layer transport layer.

Abstract

The invention discloses an HTTPS proxy forwarding method and device based on a transmission control protocol. The method comprises the steps that transmission control protocol connection is set up between a certificateless HTTPS proxy server and a client side; the certificateless HTTPS proxy server receives a security socket layer connection request from the client side; the certificateless HTTPS proxy server obtains a source station domain name by analyzing the security socket layer connection request; the certificateless HTTPS proxy server obtains a source station network interconnection protocol address corresponding to the source station domain name by inquiring a computer domain name system server; transmission control protocol connection is set up between the certificateless HTTPS proxy server and a source station corresponding to the source station network interconnection protocol address, and the certificateless HTTPS proxy server forwards the security socket layer connection request to a source station corresponding to the source station network interconnection protocol address. Through the HTTPS proxy forwarding method and device based on the transmission control protocol, a general HTTPS proxy forwarding function is achieved, and meanwhile the effect of saving IP sources is achieved.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to an HTTPS proxy forwarding method and device based on transmission control protocol. Background technique [0002] Content Delivery Network (CDN for short), by adding a new layer of network architecture to the existing Internet, the content of the website is released to the "edge" of the network closest to the user, so that the user can get the desired information nearby. content, thereby improving the response speed of users visiting the website. [0003] A secure hypertext transfer protocol (Secure Hypertext Transfer Protocol, referred to as HTTPS) proxy server (hereinafter referred to as a proxy server) based on the Transmission Control Protocol (Transmission Control Protocol, referred to as TCP), can realize the data packet without a certificate. proxy forwarding. The so-called no certificate means that the source site does not put the HTTPS certificate and private k...
