Created by Allaire, Web Distributed Data Exchange is an XML -based technology that facilitates complex-data exchange between Web programming languages (ColdFusion, Perl, ASP, Java, JavaScript, PHP, etc.).

For example, a Web site based in ColdFusion can share data with a Web site based in ASP. Data in ColdFusion would be translated into XML, sent to an ASP server, translated out of XML and into VBScript.

WDDX assigns a specific module for each supported language. The module will translate (or serialize) the native data structures into an abstract form represented as XML, or deserialize the WDDX XML into a native data structure.

WDDX supports Boolean, number, date-time, and string data types, as well as, arrays, structures, and recordsets.

Browser support for WDDX includes version 3.0 and higher Web browsers (I.E. and Netscape) for Windows, Unix and Macintosh platforms.

WDDX can be used with HTTP, SMTP, POP, and FTP.
