	Introduction
		The =Uize.Comm.Iframe.Upload= class implements support for file upload by submitting form data to a server and targeting its response back to an IFRAME.

		*DEVELOPERS:* `Ben Ilegbodu`

		In order to implement support for upload through an IFRAME, this class overrides the implementation of the =performRequest= instance method inherited from the =Uize.Comm.Iframe= base class. There are no additional methods or properties provided by this class - all the interface is provided in the =Uize.Comm= superclass.
