Updating URIs

Hi Annette,

I did some updates on the URIs used in the examples, but I was not sure of
how to update the following ones:

- URI from example 24 ( Use Web Standards as the foundation of APIs)
- URI from example 26 (Avoid Breaking Changes to Your API)

Could you please update these URIs?

Thanks!
Bernadette
