Many platforms allow applications to register schemes, which can handle URLs. On the iPhone for example I try to use tasty://oauth as a callback. This would open the application Tasty, and I could evaluate the parameters.
It works really fine, with one exception: I get this website verification warning »Warning: This website has not been verified by Yahoo!. For your security, we recommend that you continue only if you trust this website«.
This is quite senseless, because I cannot register oauth as a valid domain. What is the recommend way to get rid of this warning here? The only reason I see here is to use http://tastymobile.com/oauth as a callback, and redirect that one to tasty://oauth. Still, this really would suck.
