Client-server classes

The following table lists classes that let you send and receive data from external sources or communicate with application servers over FTP, HTTP, or HTTPS.

Note: In Flash Player 7, a SWF file can load data only from exactly the same domain from which it was served. For more information, see Flash Player security features and About allowing cross-domain data loading.

These classes are located in the Built-In Classes > Client/Server subfolder in the Actions panel.

LoadVars

The LoadVars class is an alternative to the loadVariables() action for transferring variables between a SWF file and a server in name-value pairs.
