Dynamic content has dominated the Web nowadays. Although much work has been carried out to adapt web pages for displaying on small-screen mobile devices, none of them has taken the prevalent dynamic web page into a special consideration. Dynamic pages have to be renewedly generated and transmitted over wireless networks even when a small portion changes. Since the adaptation also has to be performed on whole pages, this leads to considerable user-perceived delay. In this paper, we propose a unified framework based on fragment-based technologies which have been commonly applied in web caching. In our framework, a novel page adaptation method called constrai-ned page splitting is used to improve readability of dynamic pages, then split results rather than original contents are saved to cache in fragment granularity. Our approach can simultaneously improve readability and user-perceived delay when browsing dynamic web pages on mobile devices. In the evaluation, we use a representative Web benchmark to measure the performance of our framework. The experimental results point out that our approach is effective in improving the mobile browsing experience.
