Design the application architecture - Plan the application layers

You are designing an application in which a section of the main page will be populated by content from a third-party provider. You do not have control over the responsiveness of the client or how much information will be returned with each request. The call is to a RESTful service and will return the information formatted in Extensible Markup Language (XML). What is the best way to implement this application?

	Put a synchronous service call into the main page controller.
	Create a partial view containing only this display area and put a synchronous service call in the partial view controller.
	Design a model that handles the data call to populate the model. Create a partial view containing only this display area and put an asynchronous service call that returns this model in the partial view controller.
