Yesterday I did some maintenance of our server configuration and wondered what would be the correct way to handle unconfigured virtual hosts. E. g. what http-response should come if someone just enters the IP of our server or a domain that just isn't used for http.
At the moment, we're shipping a html-page explaining that it's an unconfigured domain, which is probably okay, but we ship it with HTTP code 200 (which means »OK«). I thought it should probably ship with some kind of error code so that search engines know there's no real webpage.
Now, reading RFC 2616 (HTTP 1.1) didn't answer the question to me. Most near is probably a 404, others we considered were 403, 503 or 204, but non of them seems to really match that situation. Maybe I should write some enhancement request to the IETF...
Comments appreciated, what would you think would be the correct status.
