A better way of sending recorded responses

[Kit Peters]

I'm developing Mojo::UserAgent::Mockable, a drop-in replacement for Mojo::UserAgent that is capable of recording and playing back HTTP interchanges. Currently, the way I'm handling playback is by rewriting the URL to point to an internal Mojolicious instance (https://github.com/PopeFelix/Mojo-UserAgent-Mockable/blob/master/lib/Mojo/UserAgent/Mockable.pm#L117) and setting $ua->server->app to the internal application (https://github.com/PopeFelix/Mojo-UserAgent-Mockable/blob/master/lib/Mojo/UserAgent/Mockable.pm#L197)

This seems to be working well so far. However, if I test it against a local Mojolicious app (e.g. as in https://github.com/PopeFelix/Mojo-UserAgent-Mockable/blob/master/t/010_playback_local.t#L34) it of course stops working, because I've set the internal server app to something else.  Is there a better way to serve recorded responses than what I'm doing currently?  I'd like this to be able to work with both local and remote apps.
