88 Server-Side ActionScript Language Reference
The LoadVars class works much like the XML class; it uses the load(), send(), and
sendAndLoad() methods to communicate with a server. The main difference between the
LoadVars class and the XML class is that LoadVars transfers ActionScript name and value
pairs, rather than an XML Document Object Model (DOM) tree stored in the XML object.
The LoadVars class follows the same security restrictions as the XML class.
