Still not quite following.

If you're doing a login, then you send the log, pwd, and the
redirect_to parameters. What you'll get back on success is a redirect
to your redirect_to page, not HTML.

If you need to intercept that on the back end to check for something
and/or return a different response, then you can use the
login_redirect filter, which gets the redirect_to value as the first
parameter, and the resulting $user object as the second parameter. To
check for a login failure at that point, you'd check for
is_wp_error($user) and if it's true, you can output your error stuff
and then exit() cleanly. No HTML response of any sort then, as far as
I can see.

BTW, since you asked, interim_login is used when a users session
cookies expire. This almost never happens.
