Abstract

A transparent proxy method, device, client and terminal, comprising: a layered service provider layer (LSP) modifies the first application layer data sending address to a transit loop layer address, and sends the application layer data to the transit loop layer; the transit loop layer receives the first application layer data from the LSP layer, and modifies the first application layer data into the second application layer data according to the preset proxy protocol; the transit loop layer sends the second application layer data To the basic service providing layer (BSP); the basic service providing layer (BSP) pushes the second application layer data to the TCP / IP protocol stack according to the proxy protocol information contained in the second application layer data. Based on the technical solution provided by the embodiment of the present invention, the LSP layer and the application layer data modification function can be decoupled, reducing the complexity of the LSP layer, thereby avoiding LSP conflicts caused by modifying the application layer data, or due to missing models. The upper layer application cannot be executed.

Description

technical field [0001] The invention belongs to the technical field of computer communication networks, and in particular relates to a transparent proxy realization method, device, client and terminal. Background technique [0002] Winsock, as a Windows network socket tool for applications, can be extended by a mechanism called "Layered Service Provider (LSP, Layered Service Provider)". Winsock LSP can be used for a very wide range of practical purposes, including Internet parental control (parental control), Web content filtering, and so on. LSP is the interface of protocols such as TCP / IP. LSP can facilitate programmers to write sniffers for monitoring system network communication, and it can also be used for browser hijacking which is common nowadays. [0003] On Windows, removing an incorrect LSP (also known as a "buggy") can cause corruption of the Winsock directory in the registry, potentially resulting in loss of all network connections. In addition, the LSP refers ...
