A client-end state maintenance method, system, client-end and application server

Abstract

The invention discloses a method, a system, a client and an application server to maintain a client state, which maintains the state of the client according to a client signature information through receiving a heartbeat packet which is provided with the client signature information and sent by the client with a fixed time interval. The method, system, client and application server leads the state information of the client to be updated with a very short fixed time interval, thus further realizing the real-time maintenance of the client state.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a client state maintenance method, system, client and application server. Background technique [0002] Currently, web browsers are used as communication clients in many application fields, such as some instant messaging systems and forums based on web pages. Similar to a general communication system, in a webpage-based communication system, the background server and each client in the system need to know the status of the web browser as a communication client in real time and accurately, so as to realize corresponding functions. [0003] However, because the webpage adopts a stateless connection mode, in the prior art, the relevant information of the client is generally recorded and saved by the session (Session) and the cookie, and the relevant information of the record is sent to the background server again at the client. When making a business request, confirm the sta...

Problems solved by technology

However, in the prior art, the current state of the client can only be known by the background server when the client makes a business request. If the web browser as the client is closed, the background server will not be able to know the state of the client in time. change, the client is still considered online, at this time, some business applications provided by the background server will not be able to complete normally

[0004] From the above description, it can be seen that in the prior art, the knowledge of the client status is uncertain, so real-time maintenance of the client status cannot be performed, resulting in the possibility that business applications cannot be completed normally.
