I was under the impression that check_http has a regex option, meaning
you can pass it a regex that ought to be able to handle this.

I've just tried this, using the standard check_http plugin you are
using. It appears not.
As soon as one string is not found it goes critical.
You could always write a custom plugin to test your websites, or much
more easily a shell wrapper plugin to call the first, if it fails, call
the second, and only if that fails go critical... not perfect though, a
better/custom plugin would serve you better.
