Install Application Initialization on Azure Web Role by hosting multiple websites

Question

I have the azure role hosted as a cloud service, I am trying to set the initialization of the application, as suggested in the following link:

but how will all my sites in this single web browser warm up?

I followed the steps in the link above. But not sure how it will be with multiple websites in a single role.
