OK, the SSL record error is because Traffic Server responds with a clear text 500 error (though
something eats the HTTP response header). We do end up in HttpTransact::HandleBlindTunnel(),
but this bails once it turns out we are not doing inbound transparency. So it looks like these
APIs only work if you are doing transparent networking :-/
