Re: [OAUTH-WG] Rename callback => callback_uri

[Eran Hammer-Lahav <[e-mail]>]

We should use the right term, not just the less conflicting term.

The Web Callback flow uses a callback from the server to the client - this is not a redirection. The User-Agent flow uses a redirection which is fundamentally different from a callback.

If you don't want to use callback and want to use the same name for both, it needs to be something more generic like client_uri.

+1 for redirect_uri -- highest semantic value imho.
