Sorry, I still don´t understand. You seem to imply that any request to
a web server which, for whatever reason, doesn´t serve the request or
doesn´t serve for the domain given in the request --- I´m not sure which
is in question here: the domain or the request --- can be considered as
an attempt to obtain information the requester is not supposed to have.
So far, my understanding has been that the requester is supposed to
receive a 4xx or 5xx error message/code when the server does not want to
or can not serve the request.
For instances when the web server gives a wrong answer to a request it
does not serve --- like sending the index page used with requests for a
different domain instead of indicating an error --- someone has
misconfigured the server, or there is a bug in the server. Neither has
anything to do with the sender of the request, other than that they
receive a wrong answer. It´s not the fault of the sender of the request
when the web server sends the wrong answer.
