Problems solved by technology

[0006] However, the current deployment method has a lot of shortcomings, mainly in the following two points: (1) the same service needs to be deployed in the DMZ area, including web servers, database servers, storage columns, etc., and the cost is relatively high; (2) For complex workflows to synchronize data through file exchange, the workload of software development is heavy

Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present invention more understandable, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] see figure 1 , the present invention can be aimed at the following network environment. Among them, the application system is deployed in the internal network, and users in the internal network can access the system directly; while users in the external network need to access the application system through the reverse proxy server in the DMZ area.

[0026] figure 2 For the process of creating a pre-connected socket. Different from the practice of conventional reverse proxy servers, in the present invention, the creation of socket connection is not that the reverse proxy server initiates a connection to the background Web server when the user request arrives, but that the background Web server first estab...

Abstract

The present invention provides a web reverse proxy method based on preconnect. A background web server actively initiates a request of establishing socket connection to a reverse proxy server, and after the reverse proxy server creates the socket connection, socket is stored into a socket resource pool. When a client browser initiates a web request to the reverse proxy server, the reverse proxy server obtains the socket from the socket resource pool and carries out request forwarding to the background web server by using the socket. The background web server receives the request and processes the request, a result is returned to the reverse proxy server, and finally the reverse proxy server returns the result to the client browser for displaying. The method has the advantages that the method is transparent to a background application system, network security requirements are satisfied in visiting an internal network, the cost of hardware and software is low, and the upgrade operation is simple.

Description

technical field [0001] The present invention is aimed at the network environment where there is firewall isolation between different network connections, and the specific isolation strategy is that a party with a high security level can access a party with a low level, and vice versa. The invention relates to a Web reverse proxy technology, in particular to a pre-connection-based Web reverse proxy method. Background technique [0002] In the power secondary system, according to the importance of different business systems, different safe working areas are divided, such as production area (area I, area II) and management area (area III, area IV). Different safe working areas specify different safety protection requirements, and propose different safety levels and protection levels. The forward / reverse isolation device deployed between different work areas improves the security of the power communication network, but at the same time it also brings inconvenience to the commun...
