Pushlet框架改进及其应用整合

Pushlet framework improvements and application integration

Pushlet是一个轻量级的Comet开源框架,在实现服务器推送方面有其独特的优点。但Pushlet在数据传输方面有较大的局限性,只能传输和存储简单格式的数据。此外,Pushlet的客户端也只能连接一个Pushlet服务端。分析了其相关主要技术并对Pushlet进行改进,使其传输具有JSON格式的丰富信息的复杂数据的能力并能连接多个Pushlet服务器端。最后结合简单的Web投票系统的设计和实现,说明了改进后的Pushlet框架的整合应用。

Pushlet is a lightweight Comet open source framework which has its unique advantage in the realization of the server push. But Pushlet has big limitation that can transfer and storage simple format of data in data transmission. In addition Pushlet client connect only one Pushlet server. This paper analyzes the major technology, and improves the Pushlet, make its have transmission JSON format with of the rich information of complex data and the ability to connect mtdtiple Pushlet server. Finally combine a simple Web vote system of designing and realizing, indicates that the improved Pushlet applieatio integration.
