Do I need to add easyXDM provider to my application that is embedded via an IFrame?

[andiw...@gmail.com]

I have Website A and Website B.

Website A (www.website-a.com) loads an application of Website B (www.website-b.com) in an IFrame.

Website B needs to make a post request to www.website-a.com/cartAdd with some post data.

Due to same origin policy this is not possible via a normal JavaScript XHR. So instead I want to use easyXDM to send a message from the application in the IFrame to Website A.

What is the way to implement the easyXDM provider?

Will the provider just be an extra page/script that sits on www.website-b.com/provider or do I have to add easyXDM to the application on Website B and load Website B via the easyXDM consumer and use the container property to actually show the application?

This is the general approach, although you could go deeper and have B  load a provider from A which then talks to its `parent.parent`. Similarly you can have A load a provider from B which then loads the real app from B in an iframe, and this talks to its parent to get things done.
