The problem is, that a HEAD request does not execute
"index_html".
Instead, the "HEAD" method from "webdav.Resource" is
called.
It uses a "content_type" and "get_size" attribute/method
to set the "Content-Type" and "Content-Length" HTTP header.
If there is no "content_type" attribute/method, the
content type is guessed (via "mimetypes.guess_type").
If there is no "get_size", the "Content-Length" is 0.
