Return a response that has no content (merely headers). The options argument is interpreted to be a hash of header names and values. This allows you to easily return a response that consists only of significant headers:
head :created, :location => person_path(@person)
It can also be used to return exceptional conditions:
return head(:method_not_allowed) unless request.post? return head(:bad_request) unless valid_request? render
