Research And Application On The Optimization Of Web Based On The Cache

With rapid development of mobile internet,various mobile devices such as mobile phones,tablets and so on have became important devices for people to work and entertain.And Web applications as cross-platform applications are widely used by developers and consumers.As the Internet has evolved from the era of the text,picture and GIF era to short video today,Web applications have evolved from content providers with simple functions to application service systems with rich content and powerful functions,which causes more data information.So we not only need higher requirements for network transmission,but also need higher requirements for performance of Web applications.In this way,a reasonable design of caching scheme according to actual application scenario should be rasied,which can not only improve data utilization and retrieval rate of Web applications,also significantly improve response speed of server.Based on the research of client-side caching and proxy caching mechanism,this paper expounds the respective advantages and disadvantages of applicable scenarios with different caching mechanisms.In combination with user's travel scene and network needs for entertainment and work in itinerary,WiFi and local area network entertainment resources are provided in vehicle environment by building a Web server,a proxy server and a browser web application.For data updated frequently in the preset geographical area,this paper use location information to optimize the caching method and puts forward a web caching scheme based on the geography-based mechanism to optimize performance of the web project.In this scheme,the location-based mechanism is added before data cache and at the same time to synchronize data according to the network state detection,which improved the mode of data cache.Finally the optimization scheme is applied in a Web application to verify its effectiveness.The optimization solution can reduce repeated network requests and in addition,the number of logical processing of web server is reduced which also reduces the energy consumption of the server.
