Sorry, I said it wrong.

What I wanted to say is:
if I request a resource with a mime-type of "text/html", I expect the
response to be "text/html", if the Accept header says "text/html" is
an acceptable format. In this case the value of "q" is not relevant
because we only have the resource in HTML format.

You can do a little test:

$ curl -o/dev/null -D- -H 'Accept: image/jpeg,image/png;q=0.1'
http://couchdb.apache.org/img/sketch.png
HTTP/1.1 200 OK
[...]
Content-Type: image/png

Since sketch.png is available only as "image/png", Apache responds
with "image/png" even if "image/jpeg" is preferred according to the
Accept header.

I ask to apply the same logic whatever the status code of the
response. If when the response is "200 OK" the content-type is
"text/html", then why not respond with the same content-type for a
"401 Unauthorized" response?

Obviously the content will be different (an html login form for the 401).
