Discussion: RP Yadis URL?

[Dick Hardt]

Hi Chris

Would you clarify these IdP initiated scenarios?

I envisioned that an IdP learned of an RP from the user have an  
initial interaction with the RP. The IdP would then save the RP URL  
for later use in case the user wanted to go back to the RP directly  
from the IdP.
