Older Integration Methods

In previous versions of Flash, Macromedia introduced ways to communicate with application servers over HTTP. These methods included getURL, loadVariables, LoadVars, and the XML object. Each method has its pros and cons and is still available in the Flash 7 player. Although we'll cover these older methods briefly, this chapter focuses primarily on new ways of accomplishing these tasks.

getURL

The getURL method was introduced in the Flash 2 player, but the GET and POST options are only available to the Flash 4 player and above. This has always been a good way to send data to the server, but it calls for the Flash movie to redirect the browser to another page. This usually consists of a Flash movie sending variables to a non-Flash page, which in turn processes the data. This is also a one-way path because you can only send data from Flash but not retrieve it.
