A session management method to improve Web applications usability on mobile network

In the traditional web applications, the valid duration of session is set short enough to decrease risk of session hijacking and to release memory of unnecessary session objects as soon as possible. When the access time exceeds the valid duration and the session expires, the clients of the web applications must send requests and data all over again from the beginning. The resubmission decrease easy to use web applications. On the mobile network, we encounter such situation frequently. To solve this problem, we propose a new session management method that manages the valid duration of session and data respectively in separate objects instead of managing them in one object together. We compare the performance of proposed method with that of conventional method and show that the proposed method realizes the convenience on the mobile network.
