AJAX MAssive Storage System (AMASS)
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.
