How can I load external dynamic data with HTML5 Data Source. In need to import data (json) from another company.

I have a asp page that generate dynamic json data. I like to import this data into HTML5 Data Source.

type: Public Feeds
source: Custom
feed url: json.asp (link to page which generate remote data)

This doesn't work because I need to link to a static json file.
