Description
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a session holding method and apparatus.
Background
HTTP (Hypertext transfer protocol) is the most widely applied protocol on the internet, because of the stateless property of the protocol itself, in many application scenarios requiring continuous communication (e.g. electronic commerce, user management, etc.) and in an environment where load balancing devices are equipped on the internet, it is often necessary for an application delivery device to forward a series of associated requests to the same server for processing. For example, in a shopping cart of an e-commerce website, data interaction is performed between a client browser and a Web page (Web) server, and when a client adds a commodity to the shopping cart, the Web server must keep shopping cart information of the client, so that no problem occurs. Therefore, it is necessary to ensure that the HTTP request message of the client requiring session maintenance is distributed to the same server for processing by using the session maintenance technology, so as to ensure the integrity and security of communication.
In the session holding method adopted in the prior art, session holding is generally realized according to specific information, cookie information, an IP (Internet Protocol) address and the like in a client request. The method for realizing session maintenance by using the IP address needs a dynamic session maintenance table, for example, source IP session maintenance and destination session maintenance, and the method does not analyze the HTTP protocol and cannot support the client attribute carried by the HTTP protocol; in addition, the cookie information is adopted to realize the session maintenance, and although a session maintenance table is not needed, the original message needs to be modified and the information of the session maintenance is added. In some networks with higher security requirements, the method may be considered as an exception or mistakenly considered as a network attack, and the support of the method on HTTP is limited to cookies, and when the browser disables the cookies, the session holding method completely fails.
Therefore, what method is adopted is one of the problems to be solved urgently, which can improve the processing capability of the HTTP protocol and ensure the integrity and security of data.
