AMASS: Ajax MAssive Storage System
The AJAX MAssive Storage System (AMASS) uses a hidden flash applet to allow
javascript AJAX applications to store an arbitrary amount of sophisticated information
on the client side. This information is permanent and persistent; if a
user closes their browser or navigates away from the web site, the information
is still present and can be retrieved later by the web page. Information stored
by web pages is private and locked to a single domain, so other web sites
can not access this information
