# Flash（常用插件）

FlashCookie是由FlashPlayer控制的客户端共享存储技术：

\
（1）类似HTTP Cookie，Flash Cookie利用 SharedObject类实现本地存储信息，SharedObject类用于在用户计算机上读取和存储有限的数据量，共享对象提供永久贮存在用户计算机上的对象之间的实时数据共享；

\
（2）本地共享对象是作为一些单独的文件来存储的，它们的文件扩展名为.SOL；

\
（3）本地共享对象并不是基于浏览器的，所以普通的用户不容易删除它们。如果要删掉它们的话，首先要知道这些文件所在的具体位置。这使得本地共享对象能够长时间的保留在本地系统上。
