The popularity of mobile devices is pushing,the traditional Internet applications shift to mobile Internet.Because of the limitation of resources and network conditions in mobile device.It lack the ability to process data effectively,so reducing the redundant data is of great significance of mobile Web.But the traditional methods such as HTTP compression and HTTP cache used to reduce redundant data have limitations.According to the above problem,this paper first analysis the redundant data elimination methods in file system,data backup,etc.Considering the characteristics of the mobile web,we propose the mobile Web delta compression model.The test results show that MWDC can effectively reduce the mobile Web network file size,but the computation of delta file in mobile client will delay the request,thus affecting the rendering of the page.Aiming at this problem,this study and put forward DSPR the improvement method based on MWDC.DSPR moves the task of request for dynamic data and the template rendering to the service side,and parallelize the process.This reduces the size of the data transfer and the number of HTTP requests,speeding up the page load time,and improving general Web performance.According to the test results on the three different Web page data sets.The transmission data size of DSPR is 15% ~ 20% of Original method,50% ~ 60% of Gzip;In the page load time,compared with the Original and MWDC,DSPR increase 1.5 ~ 8 times,1.6 ~ 6 times under different network conditions respectively.
